Gr4vy Typescript SDK (Beta)

SDK Installation

NPM

yarn add @gr4vy/sdk

Yarn

yarn add @gr4vy/sdk

Requirements

For supported JavaScript runtimes, please consult RUNTIMES.md.

SDK Example Usage

Example

import fs from "fs";
import { Gr4vy, withToken } from "@gr4vy/sdk";

async function run() {
    const gr4vy = new Gr4vy({
        server: "sandbox",
        id: "example",
        bearerAuth: withToken({
          privateKey: fs.readFileSync("private_key.pem", "utf8"),
        }),
    });

    const result = await gr4vy.transactions.list({});

    // Handle the result
    console.log(result);
}

run();

Bearer token generation

Alternatively, you can create a token for use with the SDK or with your own client library.

import { getToken } from "@gr4vy/sdk";

async function run() {
    const token = await getToken({
          privateKey: fs.readFileSync("private_key.pem", "utf8"),
    });
    console.log(token);
}

run();

Note: This will only create a token once. Use withToken to dynamically generate a token for every request.

Embed token generation

Alternatively, you can create a token for use with Embed as follows.

import { Gr4vy, getEmbedToken } from "@gr4vy/sdk";

async function run() {
    const privateKey = fs.readFileSync("private_key.pem", "utf8")

    const gr4vy = new Gr4vy({
        server: "sandbox",
        id: "example",
        bearerAuth: withToken({ privateKey }),
    });

    const checkoutSession = await gr4vy.checkoutSessions.create()

    const token = await getEmbedToken({ 
      privateKey,
      checkoutSessionId: checkoutSession.id,
      embedParams: {
        amount: 1299,
        currency: 'USD',
        buyerExternalIdentifier: 'user-1234',
      }
    });

    console.log(token);
}

run();

Note: This will only create a token once. Use withToken to dynamically generate a token for every request.

Merchant account ID selection

Depending on the key used, you might need to explicitly define a merchant account ID to use. In our API, this uses the X-GR4VY-MERCHANT-ACCOUNT-ID header. When using the SDK, you can set the merchantAccountId on every request.

const result = await gr4vy.transactions.list({
    merchantAccountId: 'merchant-12345'
})

Alternatively, the merchant account ID can also be set when initializing the SDK.

const gr4vy = new Gr4vy({
    server: "sandbox",
    id: "example",
    merchantAccountId: 'merchant-12345',
    bearerAuth: withToken({ privateKey }),
});

Webhooks verification

The SDK provides a verifyWebhook method to validate incoming webhook requests from Gr4vy. This ensures that the webhook payload is authentic and has not been tampered with.

import { verifyWebhook } from "@gr4vy/sdk";

const payload = 'your-webhook-payload'
const secret = 'your-webhook-secret'
const signatureHeader = 'signatures-from-header'
const timestampHeader = 'timestamp-from-header'
const timestampTolerance = 300 // optional, in seconds (default: 0)

try {
  verifyWebhook(
    payload,
    secret,
    signatureHeader,
    timestampHeader,
    timestampTolerance
  )
  console.log('Webhook verified successfully!')
} catch (error) {
  console.error('Webhook verification failed:', error.message)
}

Parameters

• payload: The raw payload string received in the webhook request.
• secret: The secret used to sign the webhook. This is provided in your Gr4vy dashboard.
• signatureHeader: The X-Gr4vy-Signature header from the webhook request.
• timestampHeader: The X-Gr4vy-Timestamp header from the webhook request.
• timestampTolerance: (Optional) The maximum allowed difference (in seconds) between the current time and the timestamp in the webhook. Defaults to 0 (no tolerance).

Error Handling

Some methods specify known errors which can be thrown. All the known errors are enumerated in the models/errors/errors.ts module. The known errors for a method are documented under the Errors tables in SDK docs. For example, the create method may throw the following errors:

Error Type	Status Code	Content Type
errors.Error400	400	application/json
errors.Error401	401	application/json
errors.Error403	403	application/json
errors.Error403Forbidden	403	application/json
errors.Error403Active	403	application/json
errors.Error404	404	application/json
errors.Error405	405	application/json
errors.Error409	409	application/json
errors.HTTPValidationError	422	application/json
errors.Error425	425	application/json
errors.Error429	429	application/json
errors.Error500	500	application/json
errors.Error502	502	application/json
errors.Error504	504	application/json
errors.SDKError	4XX, 5XX	*/*

If the method throws an error and it is not captured by the known errors, it will default to throwing a SDKError.

        // Other errors such as network errors, see HTTPClientErrors for more details
        throw err;
      }
    }
  }
}

run();

Validation errors can also occur when either method arguments or data returned from the server do not match the expected format. The SDKValidationError that is thrown as a result will capture the raw value that failed validation in an attribute called rawValue. Additionally, a pretty() method is available on this error that can be used to log a nicely formatted multi-line string since validation errors can list many issues and the plain error string may be difficult read when debugging.

In some rare cases, the SDK can fail to get a response from the server or even make the request due to unexpected circumstances such as network conditions. These types of errors are captured in the models/errors/httpclienterrors.ts module:

HTTP Client Error	Description
RequestAbortedError	HTTP request was aborted by the client
RequestTimeoutError	HTTP request timed out due to an AbortSignal signal
ConnectionError	HTTP client was unable to make a request to a server
InvalidRequestError	Any input used to create a request is invalid
UnexpectedClientError	Unrecognised or unexpected error

Server Selection

Select Server by Name

You can override the default server globally by passing a server name to the server: keyof typeof ServerList optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the names associated with the available servers:

Name	Server	Variables	Description
production	https://api.{id}.gr4vy.app	id
sandbox	https://api.sandbox.{id}.gr4vy.app	id

If the selected server has variables, you may override its default values through the additional parameters made available in the SDK constructor:

Variable	Parameter	Default	Description
id	id: string	"example"	The subdomain for your Gr4vy instance.

Example

import { Gr4vy } from "@gr4vy/sdk";

const gr4vy = new Gr4vy({
  server: "sandbox",
  id: "<id>",
  server: "sandbox",
  id: "example",
  bearerAuth: withToken({
    privateKey: fs.readFileSync("private_key.pem", "utf8"),
  }),
});

async function run() {
  const result = await gr4vy.accountUpdater.jobs.create(
    {
      paymentMethodIds: [
        "ef9496d8-53a5-4aad-8ca2-00eb68334389",
        "f29e886e-93cc-4714-b4a3-12b7a718e595",
      ],
    },
    1,
    "default",
  );

  // Handle the result
  console.log(result);
}

run();

Override Server URL Per-Client

The default server can also be overridden globally by passing a URL to the serverURL: string optional parameter when initializing the SDK client instance. For example:

import { Gr4vy } from "@gr4vy/sdk";

const gr4vy = new Gr4vy({
  serverURL: "https://api.example.gr4vy.app",
  server: "sandbox",
  id: "example",
  bearerAuth: withToken({
    privateKey: fs.readFileSync("private_key.pem", "utf8"),
  }),
});

async function run() {
  const result = await gr4vy.accountUpdater.jobs.create(
    {
      paymentMethodIds: [
        "ef9496d8-53a5-4aad-8ca2-00eb68334389",
        "f29e886e-93cc-4714-b4a3-12b7a718e595",
      ],
    },
    1,
    "default",
  );

  // Handle the result
  console.log(result);
}

run();

Custom HTTP Client

The TypeScript SDK makes API calls using an HTTPClient that wraps the native Fetch API. This client is a thin wrapper around fetch and provides the ability to attach hooks around the request lifecycle that can be used to modify the request or handle errors and response.

The HTTPClient constructor takes an optional fetcher argument that can be used to integrate a third-party HTTP client or when writing tests to mock out the HTTP client and feed in fixtures.

The following example shows how to use the "beforeRequest" hook to to add a custom header and a timeout to requests and how to use the "requestError" hook to log errors:

import { Gr4vy } from "@gr4vy/sdk";
import { HTTPClient } from "@gr4vy/sdk/lib/http";

const httpClient = new HTTPClient({
  // fetcher takes a function that has the same signature as native `fetch`.
  fetcher: (request) => {
    return fetch(request);
  }
});

httpClient.addHook("beforeRequest", (request) => {
  const nextRequest = new Request(request, {
    signal: request.signal || AbortSignal.timeout(5000)
  });

  nextRequest.headers.set("x-custom-header", "custom value");

  return nextRequest;
});

httpClient.addHook("requestError", (error, request) => {
  console.group("Request Error");
  console.log("Reason:", `${error}`);
  console.log("Endpoint:", `${request.method} ${request.url}`);
  console.groupEnd();
});

const sdk = new Gr4vy({ httpClient });

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme	Environment Variable
bearerAuth	http	HTTP Bearer	GR4VY_BEARER_AUTH

To authenticate with the API the bearerAuth parameter must be set when initializing the SDK client instance. For example:

import { Gr4vy } from "@gr4vy/sdk";

const gr4vy = new Gr4vy({
  server: "sandbox",
  id: "example",
  bearerAuth: withToken({
    privateKey: fs.readFileSync("private_key.pem", "utf8"),
  }),
});

async function run() {
  const result = await gr4vy.accountUpdater.jobs.create(
    {
      paymentMethodIds: [
        "ef9496d8-53a5-4aad-8ca2-00eb68334389",
        "f29e886e-93cc-4714-b4a3-12b7a718e595",
      ],
    },
    1,
    "default",
  );

  // Handle the result
  console.log(result);
}

run();

SDK Installation

The SDK can be installed with either npm, pnpm, bun or yarn package managers.

NPM

npm add @gr4vy/sdk

PNPM

pnpm add @gr4vy/sdk

Bun

bun add @gr4vy/sdk

Yarn

yarn add @gr4vy/sdk zod

# Note that Yarn does not install peer dependencies automatically. You will need
# to install zod as shown above.

Model Context Protocol (MCP) Server

This SDK is also an installable MCP server where the various SDK methods are exposed as tools that can be invoked by AI applications.

Node.js v20 or greater is required to run the MCP server from npm.

Claude installation steps

Add the following server definition to your claude_desktop_config.json file:

{
  "mcpServers": {
    "Gr4vy": {
      "command": "npx",
      "args": [
        "-y", "--package", "@gr4vy/sdk",
        "--",
        "mcp", "start",
        "--bearer-auth", "...",
        "--merchant-account-id", "..."
      ]
    }
  }
}

Cursor installation steps

Create a .cursor/mcp.json file in your project root with the following content:

{
  "mcpServers": {
    "Gr4vy": {
      "command": "npx",
      "args": [
        "-y", "--package", "@gr4vy/sdk",
        "--",
        "mcp", "start",
        "--bearer-auth", "...",
        "--merchant-account-id", "..."
      ]
    }
  }
}

You can also run MCP servers as a standalone binary with no additional dependencies. You must pull these binaries from available Github releases:

curl -L -o mcp-server \
    https://github.com/{org}/{repo}/releases/download/{tag}/mcp-server-bun-darwin-arm64 && \
chmod +x mcp-server

If the repo is a private repo you must add your Github PAT to download a release -H "Authorization: Bearer {GITHUB_PAT}".

{
  "mcpServers": {
    "Todos": {
      "command": "./DOWNLOAD/PATH/mcp-server",
      "args": [
        "start"
      ]
    }
  }
}

For a full list of server arguments, run:

npx -y --package @gr4vy/sdk -- mcp start --help

SDK Example Usage

Example

import { Gr4vy } from "@gr4vy/sdk";

const gr4vy = new Gr4vy({
  server: "sandbox",
  id: "example",
  bearerAuth: withToken({
    privateKey: fs.readFileSync("private_key.pem", "utf8"),
  }),
});

async function run() {
  const result = await gr4vy.accountUpdater.jobs.create(
    {
      paymentMethodIds: [
        "ef9496d8-53a5-4aad-8ca2-00eb68334389",
        "f29e886e-93cc-4714-b4a3-12b7a718e595",
      ],
    },
    1,
    "default",
  );

  // Handle the result
  console.log(result);
}

run();

Pagination

Some of the endpoints in this SDK support pagination. To use pagination, you make your SDK calls as usual, but the returned response object will also be an async iterable that can be consumed using the for await...of syntax.

Here's an example of one such pagination call:

import { Gr4vy } from "@gr4vy/sdk";

const gr4vy = new Gr4vy({
  server: "sandbox",
  id: "example",
  bearerAuth: withToken({
    privateKey: fs.readFileSync("private_key.pem", "utf8"),
  }),
});

async function run() {
  const result = await gr4vy.buyers.list({
    cursor: "ZXhhbXBsZTE",
    search: "John",
    externalIdentifier: "buyer-12345",
  });

  for await (const page of result) {
    // Handle the page
    console.log(page);
  }
}

run();

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:

import { Gr4vy } from "@gr4vy/sdk";

const gr4vy = new Gr4vy({
  server: "sandbox",
  id: "example",
  bearerAuth: withToken({
    privateKey: fs.readFileSync("private_key.pem", "utf8"),
  }),
});

async function run() {
  const result = await gr4vy.accountUpdater.jobs.create(
    {
      paymentMethodIds: [
        "ef9496d8-53a5-4aad-8ca2-00eb68334389",
        "f29e886e-93cc-4714-b4a3-12b7a718e595",
      ],
    },
    1,
    "default",
    {
      retries: {
        strategy: "backoff",
        backoff: {
          initialInterval: 1,
          maxInterval: 50,
          exponent: 1.1,
          maxElapsedTime: 100,
        },
        retryConnectionErrors: false,
      },
    },
  );

  // Handle the result
  console.log(result);
}

run();

If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:

import { Gr4vy } from "@gr4vy/sdk";

const gr4vy = new Gr4vy({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
  server: "sandbox",
  id: "example",
  bearerAuth: withToken({
    privateKey: fs.readFileSync("private_key.pem", "utf8"),
  }),
});

async function run() {
  const result = await gr4vy.accountUpdater.jobs.create(
    {
      paymentMethodIds: [
        "ef9496d8-53a5-4aad-8ca2-00eb68334389",
        "f29e886e-93cc-4714-b4a3-12b7a718e595",
      ],
    },
    1,
    "default",
  );

  // Handle the result
  console.log(result);
}

run();

Standalone functions

All the methods listed above are available as standalone functions. These functions are ideal for use in applications running in the browser, serverless runtimes or other environments where application bundle size is a primary concern. When using a bundler to build your application, all unused functionality will be either excluded from the final bundle or tree-shaken away.

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass a logger that matches console's interface as an SDK option.

[!WARNING] Beware that debug logging will reveal secrets, like API tokens in headers, in log messages printed to a console or files. It's recommended to use this feature only during local development and not in production.

import { Gr4vy } from "@gr4vy/sdk";

const sdk = new Gr4vy({ debugLogger: console });

You can also enable a default debug logger by setting an environment variable GR4VY_DEBUG to true.

Development

Testing

To run the tests, install NPM and run the following.

npm install
npx vitest

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Feel free to open a PR or a Github issue as a proof of concept and we'll do our best to include it in a future release!
