Usage

Importing in your project file

var BlockBee = require('@blockbee/api')

Generating a new Address

const bb = new BlockBee(coin, myAddress, callbackUrl, params, blockbeeParams, apiKey)

const address = await bb.getAddress()

Where:

• coin is the coin you wish to use, from BlockBee's supported currencies (e.g 'btc', 'eth', 'erc20_usdt', ...).
• myAddress is your own crypto address, where your funds will be sent to. It's optional, you can leave it empty (e.g '') if you are setting it up in BlockBee's dashboard.
• callbackUrl is the URL that will be called upon payment.
• params is any parameter you wish to send to identify the payment, such as {orderId: 1234}.
• blockbeeParams parameters that will be passed to BlockBee _(check which extra parameters are available here: https://docs.blockbee.io/#operation/create).
• apiKey is the API Key provided by BlockBee's dashboard.
• address is the newly generated address, that you will show your users in order to receive payments.

Getting notified when the user pays

Once your customer makes a payment, BlockBee will send a callback to your callbackUrl. This callback information is by default in GET but you can se it to POST by setting post: 1 in blockbeeParams. The parameters sent by BlockBee in this callback can be consulted here: https://docs.blockbee.io/#operation/confirmedcallbackget

Checking the logs of a request

const bb = new BlockBee(coin, myAddress, callbackUrl, params, blockbeeParams, apiKey)

const data = await bb.checkLogs()

Same parameters as before, the data returned can b e checked here: https://docs.blockbee.io/#operation/logs

Generating a QR code

const bb = new BlockBee(coin, myAddress, callbackUrl, params, blockbeeParams, apiKey)
    
const address = await bb.getAddress()

// ...

const qrCode = await bb.getQrcode(value, size)

For object creation, same parameters as before. You must first call ``getAddress` as this method requires the payment address to have been created.

For QR Code generation:

• value is the value requested to the user in the coin to which the request was done. Optional, can be empty if you don't wish to add the value to the QR Code.
• size Size of the QR Code image in pixels. Optional, leave empty to use the default size of 512.
• apiKey is the API Key provided by BlockBee's dashboard.

Response is an object with qr_code (base64 encoded image data) and payment_uri (the value encoded in the QR), see https://docs.blockbee.io/#operation/qrcode for more information.

Estimating transaction fees

const fees = await BlockBee.getEstimate(coin, apiKey, addresses, priority)

Where:

• coin is the coin you wish to check, from BlockBee's supported currencies (e.g 'btc', 'eth', 'erc20_usdt', ...)
• apiKey is the API Key provided by BlockBee's dashboard.
• addresses The number of addresses to forward the funds to. Optional, defaults to 1.
• priority Confirmation priority, (check this article to learn more about it). Optional, defaults to default.

Response is an object with estimated_cost and estimated_cost_usd, see https://docs.blockbee.io/#operation/estimate for more information.

Converting between coins and fiat

const conversion = await BlockBee.getConvert(coin, value, from, apiKey)

Where:

• coin the target currency to convert to, from BlockBee's supported currencies (e.g 'btc', 'eth', 'erc20_usdt', ...)
• value value to convert in from.
• from currency to convert from, FIAT or crypto.
• apiKey is the API Key provided by BlockBee's dashboard.

Response is an object with value_coin and exchange_rate, see https://docs.blockbee.io/#operation/convert for more information.

Getting supported coins

const supportedCoins = await BlockBee.getSupportedCoins(apiKey)

Where:

• apiKey is the API Key provided by BlockBee's dashboard.

Response is an array with all support coins.
