Including Skyflow-React
Requirements
- The minimum supported version of React is v16.8.0. If you use an older version, upgrade React to use this library
Installation
Using npm
npm install --save skyflow-react-js
Initializing Skyflow-React
React components are wrapped in Skyflow provider which takes in config object and SDK internally initializes a Skyflow client.
import {SkyflowElements, LogLevel, Env} from 'skyflow-react-js';
const root = ReactDOM.createRoot(
document.getElementById('root') as HTMLElement
);
const config = {
vaultID: 'string',
vaultURL: 'string',
getBearerToken: helperFunc,
options: {
logLevel: LogLevel.DEBUG,
env: Env.DEV,
},
};
root.render(
<SkyflowElements config={config}>
<App />
</SkyflowElements>
);
For the getBearerToken
parameter, pass in a helper function that retrieves a Skyflow bearer token from your backend. This function will be invoked when the SDK needs to insert or retrieve data from the vault. A sample implementation is shown below:
For example, if the response of the consumer tokenAPI is in the below format
{
'accessToken': string,
'tokenType': string
}
then, your getBearerToken Implementation should be as below
const getBearerToken = () => {
return new Promise((resolve, reject) => {
const Http = new XMLHttpRequest()
Http.onreadystatechange = () => {
if (Http.readyState === 4) {
if (Http.status === 200) {
const response = JSON.parse(Http.responseText)
resolve(response.accessToken)
} else {
reject('Error occured')
}
}
}
Http.onerror = (error) => {
reject('Error occured')
}
const url = 'https://api.acmecorp.com/skyflowToken'
Http.open('GET', url)
Http.send()
})
}
For logLevel
parameter, there are 4 accepted values in LogLevel
-
DEBUG
When LogLevel.DEBUG
is passed, all level of logs will be printed(DEBUG, INFO, WARN, ERROR).
-
INFO
When LogLevel.INFO
is passed, INFO logs for every event that has occurred during the SDK flow execution will be printed along with WARN and ERROR logs.
-
WARN
When LogLevel.WARN
is passed, WARN and ERROR logs will be printed.
-
ERROR
When LogLevel.ERROR
is passed, only ERROR logs will be printed.
Note
:
- The ranking of logging levels is as follows : DEBUG < INFO < WARN < ERROR
- Since
logLevel
is optional, by default the logLevel will be ERROR
.
For env
parameter, there are 2 accepted values in Env
Note
:
- Since
env
is optional, by default the env will be PROD
. - Use
env
option with caution, make sure the env is set to PROD
when using skyflow-react-js
in production.
Securely collecting data client-side
Using Skyflow Elements to collect data
Skyflow Elements provide developers with pre-built form elements to securely collect sensitive data client-side. These elements are hosted by Skyflow and injected into your web page as iFrames. This reduces your PCI compliance scope by not exposing your front-end application to sensitive data. Follow the steps below to securely collect data with Skyflow Elements.
Step 1: Create a container
First create a container for the form elements using the useCollectContainer
hook as show below:
const container = useCollectContainer()
Step 2: Create a collect Element
import { CardNumberElement} from 'skyflow-react-js';
<CardNumberElement
table='<TABLE_NAME>'
container='<CONTAINER>'
column='<COLUMN_NAME>'
… props
/>
The following props
can be passed to Skyflow collect Element:
{
container: 'CollectContainer'
table: 'string',
column: 'string',
id: string,
classes: {},
label: 'string',
placeholder: 'string',
validations: [],
options: {},
onChange: Function,
onFocus: Function,
onBlur: Function,
onReady: Function,
}
The table
and column
fields indicate which table and column in the vault the Element corresponds to.
Note:
- Use dot delimited strings to specify columns nested inside JSON fields (e.g.
address.street.line1
)
All elements can be styled using JSS syntax.
An example of styling an element with makeSkyflowStyles
hook :
import { useMakeSkyflowStyles } from 'skyflow-react-js'
const useSkyflowStyles = useMakeSkyflowStyles({
inputStyles: {
base: {
color: '#013370',
},
complete: {
color: '#4caf50',
},
empty: {},
focus: {},
invalid: {},
cardIcon: {
position: 'absolute',
left: '8px',
bottom: 'calc(50% - 12px)',
},
copyIcon: {
position: 'absolute',
right: '8px',
},
},
labelStyles: {
base: {
color: '#0D4370',
},
},
errorTextStyles: {
base: {
color: '#f44336',
},
},
})
The inputStyles
field accepts a style object which consists of CSS properties that should be applied to the form element in the following states:
base
: all other variants inherit from these styles.complete
: applied when the Element has valid input.empty
: applied when the Element has no input.focus
: applied when the Element has focus.invalid
: applied when the Element has invalid input.cardIcon
: applied to the card type icon in CARD_NUMBER
Element.copyIcon
: applied to copy icon in Elements when enableCopy
option is true.
The states that are available for labelStyles
are base
and focus
.
An example of a labelStyles object:
labelStyles: {
base: {
fontSize: '12px',
fontWeight: 'bold'
},
focus: {
color: '#1d1d1d'
}
}
The state that is available for errorTextStyles
is only the base
state, it shows up when there is some error in the collect element.
An example of a errorTextStyles object:
errorTextStyles: {
base: {
color: '#f44336',
}
}
We support the following collect elements in the react SDK:
CardHolderNameElement
CardNumberElement
ExpirationDateElement
CVVElement
PinElement
ExpirationDateElement
ExpirationMonthElement
ExpirationYearElement
InputFieldElement
The InputFieldElement type is a custom UI element without any built-in validations. See the section on validations for more information on validations.
Along with Collect Element we can define other options which takes a object of optional parameters as described below:
const options = {
required: false,
enableCardIcon: true,
format: String,
enableCopy: false,
}
required
parameter indicates whether the field is marked as required or not. If not provided, it defaults to false
enableCardIcon
parameter indicates whether the icon is visible for the CARD_NUMBER element, defaults to true
format
parameter takes string value and indicates the format pattern applicable to the element type, It's currently only applicable to EXPIRATION_DATE
and EXPIRATION_YEAR
element types.
enableCopy
parameter indicates whether the copy icon is visible in collect and reveal elements.
The values that are accepted for EXPIRATION_DATE
are
MM/YY
(default)MM/YYYY
YY/MM
YYYY/MM
The values that are accepted for EXPIRATION_YEAR
are
NOTE
: If not specified or invalid value is passed to the format
then it takes default value.
Step 3: Collect data from Elements
When the form is ready to be submitted, call the collect(options?)
method on the container object. The options
parameter takes a object of optional parameters as shown below:
tokens
: indicates whether tokens for the collected data should be returned or not. Defaults to 'true'additionalFields
: Non-PCI elements data to be inserted into the vault which should be in the records
object format.upsert
: To support upsert operations while collecting data from Skyflow elements, pass the table and column marked as unique in the table.
const options = {
tokens: true,
additionalFields: {
records: [
{
table: 'string',
fields: {
column1: 'value',
},
},
],
},
upsert: [
{
table: 'string',
column: 'value',
},
],
}
container.collect(options)
End to end example of collecting data with Skyflow Elements
import React from 'react'
import { CardNumberElement, useCollectContainer, useMakeSkyflowStyles } from 'skyflow-react-js'
const App = () => {
const container = useCollectContainer()
const useStyles = useMakeSkyflowStyles({

"cvv": "l4907186-e7e2-466f-91e5-985e12c2bcbc1"
}
}
]
}
Validations:
Skyflow-React which internally uses Skyflow-JS SDK provides two types of validations on Collect Elements
1. Default Validations:
Every Collect Element except of type InputFieldElement
has a set of default validations listed below:
CARD_NUMBER
: Card number validation with checkSum algorithm(Luhn algorithm).
Available card lengths for defined card types are [12, 13, 14, 15, 16, 17, 18, 19].
A valid 16 digit card number will be in the format - XXXX XXXX XXXX XXXX
CARD_HOLDER_NAME
: Name should be 2 or more symbols, valid characters should match pattern - ^([a-zA-Z\\ \\,\\.\\-\\']{2,})$
CVV
: Card CVV can have 3-4 digitsEXPIRATION_DATE
: Any date starting from current month. By default valid expiration date should be in short year format - MM/YY
PIN
: Can have 4-12 digits
2. Custom Validations:
Custom validations can be added to any element which will be checked after the default validations have passed. The following Custom validation rules are currently supported:
REGEX_MATCH_RULE
: You can use this rule to specify any Regular Expression to be matched with the input field value
const regexMatchRule = {
type: REGEX_MATCH_RULE,
params: {
regex: RegExp,
error: string,
},
}
LENGTH_MATCH_RULE
: You can use this rule to set the minimum and maximum permissible length of the input field value
const lengthMatchRule = {
type: LENGTH_MATCH_RULE,
params: {
min: number,
max: number,
error: string,
},
}
The Sample for using custom validations:
import {CardNumberElement, REGEX_MATCH_RULE, LENGTH_MATCH_RULE} from 'skyflow-react-js';
const alphabetsOnlyRegexRule = {
type: REGEX_MATCH_RULE,
params: {
regex: /^[A-Za-z]+$/,
error: 'Only alphabets are allowed'
}
};
const lengthRule = {
type: LENGTH_MATCH_RULE,
params: {
min: 4,
max: 6,
error: 'Must be between 4 and 6 alphabets'
}
};
const Form = (props) => {
return (
<CardNumberElement
container='COLLECT CONTAINER'
table='<TABLE_NAME>'
column='<COLUMN_NAME>'
validations={[alphabetsOnlyRegexRule, lengthRule]}
...props
/>
);
};
Event Listener on Collect Elements
Helps to communicate with Skyflow elements / iframes by listening to an event. Event listeners can be triggered by passing the handler methods as props to the Element components.
There are 4 events which SDK supports:
-
CHANGE
Change event is triggered when the Element's value changes.
-
READY
Ready event is triggered when the Element is fully rendered
-
FOCUS
Focus event is triggered when the Element gains focus
-
BLUR
Blur event is triggered when the Element loses focus.
The handler function(state) => void
is a callback function you provide, that will be called when the event is fired with the state object as shown below.
state: {
elementType: Skyflow.ElementType
isEmpty: boolean
isFocused: boolean
isValid: boolean
value: string
}
Note:
Values of SkyflowElements will be returned in element state object only when env
is DEV
, else it is empty string i.e, '', but in case of CARD_NUMBER type element when the env
is PROD
for all the card types except AMEX, it will return first eight digits, for AMEX it will return first six digits and rest all digits in masked format.
Example Usage of Event Listener on Collect Elements
import React from 'react'
import { CardNumberElement, CardHolderNameElement, useCollectContainer } from 'skyflow-react-js'
const App = () => {
const container = useCollectContainer()
const handleCollect = () => {
const response = container.collect()
response
.then((res: unknown) => {
console.log(JSON.stringify(res))
})
.catch((e: unknown) => {
console.log(e)
})
}
const handleOnChange = (changeState: unknown) => {
console.log('Change', changeState)
}
const handleOnBlur = (changeState: unknown) => {
console.log('Blur', changeState)
}
return (
<div className='App'>
<header className='App-header'>
<CardNumberElement
container={container}
table={'table1'}
column={'card_number'}
label={'Collect Card Number'}
onChange={handleOnChange}
onBlur={handleOnBlur}
/>
<CardHolderNameElement
container={container}
table={'table1'}
column={'first_name'}
label={'Collect Card Holder Name'}
onChange={handleOnChange}
onBlur={handleOnBlur}
/>
<button onClick={handleCollect}>Collect</button>
</header>
</div>
)
}
export default App
Sample Element state object when env
is DEV
{
elementType: 'CARDHOLDER_NAME',
isEmpty: false,
isFocused: true,
isValid: true,
value: 'John',
};
{
elementType: 'CARD_NUMBER',
isEmpty: false,
isFocused: true,
isValid: true,
value: '4111111111111111',
};
Sample Element state object when env
is PROD
{
elementType: 'CARDHOLDER_NAME',
isEmpty: false,
isFocused: true,
isValid: true,
value: '',
};
{
elementType: 'CARD_NUMBER',
isEmpty: false,
isFocused: true,
isValid: true,
value: '41111111XXXXXXXX',
};
Securely collecting data client-side using Composable Elements
Composable Elements combine multiple Skyflow Elements in a single iframe, letting you create multiple Skyflow Elements in a single row. The following steps create a composable element and securely collect data through it.
Step 1: Create a composable container
Create a container for the composable element using the useComposableContainer hook of the Skyflow client:
const container = useComposableContainer(containerOptions)
The container requires an options object that contains the following keys:
-
layout
: An array that indicates the number of rows in the container and the number of elements in each row. The index value of the array defines the number of rows, and each value in the array represents the number of elements in that row, in order.
For example: [2,1]
means the container has two rows, with two elements in the first row and one element in the second row.
Note
: The sum of values in the layout array should be equal to the number of elements created
-
styles
: CSS styles to apply to the composable container.
-
errorTextStyles
: CSS styles to apply if an error is encountered.
const options = {
layout: [2, 1],
styles: {
base: {
border: '1px solid #DFE3EB',
padding: '8px',
borderRadius: '4px',
margin: '12px 2px',
},
},
errorTextStyles: {
base: {
color: 'red',
},
},
};
Step 2: Create Composable Elements
Composable Elements use the following format. Create other elements within the Composable Element.
import {
ComposableContainer,
CardHolderNameElement,
CardNumberElement,
} from "skyflow-react-js";
<ComposableContainer id="<ID>" container="<CONTAINER>">
<CardHolderNameElement
id="<ID>"
table="<TABLE_NAME>"
container="<CONTAINER>"
column="<COLUMN_NAME>"
... props
/>
<CardNumberElement
id="<ID>"
table="<TABLE_NAME>"
container="<CONTAINER>"
column="<COLUMN_NAME>"
... props
/>
</ComposableContainer>
The following props
can be passed to Skyflow Composable Element:
{
container: 'ComposableContainer'
table: 'string',
column: 'string',
id: string,
classes: {},
label: 'string',
placeholder: 'string',
validations: [],
options: {},
onChange: Function,
onFocus: Function,
onBlur: Function,
onReady: Function,
}
The table
and column
fields indicate which table and column in the vault the Element correspond to.
Note: Use dot-delimited strings to specify columns nested inside JSON fields (for example, address.street.line1
).
All elements can be styled with JSS syntax.
An example of styling an element with makeSkyflowStyles
hook:
const useSkyflowStyles = makeSkyflowStyles({
inputStyles: {
base: {
color: "#013370",
},
complete: {
color: "#4caf50",
},
empty: {},
focus: {},
invalid: {},
cardIcon: {
position: "absolute",
left: "8px",
bottom: "calc(50% - 12px)"
},
copyIcon: {
position: "absolute",
right: "8px",
}
},
labelStyles: {
base: {
color: "#0D4370",
}
},
errorTextStyles: {
base: {
color: "#f44336",
}
}
})
The inputStyles
field accepts an object of CSS properties to apply to the form element in the following states:
base
: all variants inherit from these stylescomplete
: applied when the Element has valid inputempty
: applied when the Element has no inputfocus
: applied when the Element has focusinvalid
: applied when the Element has invalid inputcardIcon
: applied to the card type icon in CARD_NUMBER ElementcopyIcon
: applied to copy icon in Elements when enableCopy option is true
An example of an inputStyles
object:
inputStyles: {
base: {
border: '1px solid #eae8ee',
padding: '10px 16px',
borderRadius: '4px',
color: '#1d1d1d',
},
complete: {
color: '#4caf50',
},
empty: {},
focus: {},
invalid: {
color: '#f44336',
},
cardIcon: {
position: 'absolute',
left: '8px',
bottom: 'calc(50% - 12px)',
},
copyIcon: {
position: 'absolute',
right: '8px',
},
}
The labelStyles
field supports the base
and focus
states.
An example labelStyles
object:
labelStyles: {
base: {
fontSize: '12px',
fontWeight: 'bold'
},
focus: {
color: '#1d1d1d'
}
}
The errorTextStyles
field only supports the base
state, which appears when there is an error in the composable element.
An example errorTextStyles
object:
errorTextStyles: {
base: {
color: '#f44336'
}
}
The React SDK supports the following composable elements:
CardHolderNameElement
CardNumberElement
ExpirationDateElement
CVVElement
PinElement
ExpirationDateElement
ExpirationMonthElement
ExpirationYearElement
InputFieldElement
Note
: Only when the entered value in the below composable elements is valid, the focus shifts automatically. The element types are:
CardNumberElement
ExpirationDateElement
ExpirationMonthElement
ExpirationYearElement
The InputFieldElement
type is a custom UI element without any built-in validations. For information on validations, see validations.
Along with the Composable Element definition, you can define additional options for the element:
const options = {
required: false,
enableCardIcon: true,
format: String,
enableCopy: false
}
required
: Whether or not the field is marked as required. Defaults to false
.enableCardIcon
: Whether or not the icon is visible for the CARD_NUMBER element. Defaults to true
.format
: Format pattern for the element. Only applicable to EXPIRATION_DATE and EXPIRATION_YEAR element types.enableCopy
: Whether or not the copy icon is visible in collect and reveal elements. Defaults to false
.
The accepted EXPIRATION_DATE
values are
MM/YY
(default)MM/YYYY
YY/MM
YYYY/MM
The accepted EXPIRATION_YEAR
values are
Step 3: Collect data from Elements
When the form is ready to be submitted, call the collect(options?)
method on the container object. The options parameter takes an object of optional parameters as follows:
tokens
: Whether or not tokens for the collected data are returned. Defaults to 'true'additionalFields
: Non-PCI elements data to insert into the vault, specified in the records object format.upsert
: To support upsert operations, the table containing the data and a column marked as unique in that table.
const options = {
tokens: true,
additionalFields: {
records: [
{
table: 'string',
fields: {
column1: 'value',
},
},
],
},
upsert: [
{
table: 'string',
column: 'value',
},
],
};

Set an event listener on Composable Elements:
You can communicate with Skyflow Elements by listening to element events:
The SDK supports four events:
CHANGE
: Triggered when the Element's value changes.READY
: Triggered when the Element is fully rendered.FOCUS
: Triggered when the Element gains focus.BLUR
: Triggered when the Element loses focus.
The handler function(state) => void
is a callback function you provide that's called when the event is fired with a state object that uses the following schema:
state : {
elementType: Skyflow.ElementType
isEmpty: boolean
isFocused: boolean
isValid: boolean
value: string
}
Note
: Events only include element values when in the state object when env is DEV
. By default, value is an empty string.

Set an event listener on a composable container
Currently, the SDK supports one event:
SUBMIT
: Triggered when the Enter
key is pressed in any container element.
The handler function(void) => void
is a callback function you provide that's called when the `SUBMIT' event fires.
Example usage of event listener on composable container
import React from 'react';
import {
CardNumberElement,
CVVElement,
useMakeSkyflowStyles,
useComposableContainer,
ComposableContainer,
CardHolderNameElement,
} from 'skyflow-react-js';
const ComposableElements = () => {
const useStyles = useMakeSkyflowStyles({
inputStyles: {
base: {
color: '#1d1d1d',
},
},
labelStyles: {},
errorTextStyles: {
base: {
display: 'none'
},
},
});
const classes = useStyles();
const handleOnSubmit = () => {
console.log('Submit Event Listener is being Triggered.');
};
const containerOptions = {
layout: [1, 2],
styles: {
base: {
border: '1px solid #DFE3EB',
padding: '8px',
borderRadius: '4px',
margin: '12px 2px',
}
}
}
const container = useComposableContainer(containerOptions);
const handleCollect = () => {
const response = container?.collect();
response
?.then((res: any) => {
console.log(JSON.stringify(res));
})
.catch((e: any) => {
console.log(e);
});
};
return (
<div className='CollectElements' >
<ComposableContainer
id='composecontainer'
container={container}
onSubmit={handleOnSubmit} // Pass onSubmit handler.
>
<CardHolderNameElement
id='collectCardHolderName'
container={container}
table='pii_fields'
classes={classes}
placeholder='Cardholder Name'
column='first_name'
/>
<CardNumberElement
id='collectCardNumber'
container={container}
table='pii_fields'
classes={classes}
placeholder='XXXX XXXX XXXX XXXX'
column='card_number'
/>
<CVVElement
id='cvv'
container={container}
table='pii_fields'
classes={classes}
placeholder='CVC'
column='cvv'
/>
</ComposableContainer >
<button onClick={handleCollect}>Collect</button>
</div>

Securely revealing data client-side
Using Skyflow Elements to reveal data
Skyflow Elements can be used to securely reveal data in a browser without exposing your front end to the sensitive data. This is great for use cases like card issuance where you may want to reveal the card number to a user without increasing your PCI compliance scope.
Step 1: Create a container
To start, create a container using the useRevealContainer()
method of the Skyflow client as shown below.
const revealContainer = useRevealContainer()
Step 2: Create a reveal element
import {RevealElement} from 'skyflow-react-js';
import Skyflow from 'skyflow-js';
<RevealElement
token='<DATA_TOKEN>'
container='<CONTAINER>'
...props
/>
The following props
can be passed to Skyflow reveal element:
{
container: 'RevealContainer',
token:'string',
id: string,
classes: {},
label: 'string',
redaction: Skyflow.RedactionType
}
Note
:
- The
inputStyles
, labelStyles
and errorTextStyles
parameters accepts a styles object as described in the previous section for collecting data. But for reveal element, inputStyles
accepts only base
variant and copyIcon
style object. redaction
defaults to RedactionType.PLAIN_TEXT
.
Redaction Types
There are four accepted values for RedactionType:
- PLAIN_TEXT
- MASKED
- REDACTED
- DEFAULT
End to end example using Reveal Element
import React from 'react'
import { RevealElement, useRevealContainer, useMakeSkyflowStyles } from 'skyflow-react-js'
import Skyflow from 'skyflow-js';
const App = () => {
const revealContainer = useRevealContainer()
const useStyles = useMakeSkyflowStyles({
inputStyles: {
base: {
border: '1px solid black',
borderRadius: '4px',
color: '#1d1d1d',
padding: '10px 16px',
},
copyIcon: {
position: 'absolute',
right: '8px',
top: 'calc(50% - 10px)',
},
},
labelStyles: {
base: {
fontSize: '16px',
fontWeight: 'bold',
},
},
errorTextStyles: {
base: {
color: 'red',
},
},
})
const handleReveal = () => {
revealContainer
.reveal()
.then((res) => {
console.log(res)
})
.catch((err) => {
console.log(err)
})
}
const classes = useStyles()
return (
<div className='App'>
<header className='App-header'>
<RevealElement
container={revealContainer}
token={'1404-8379-9069-7378'}
label={'Reveal Card Number'}

/>
<button onClick={handleReveal}>Reveal</button>
</header>
</div>
