BlindPay Node.js SDK

The official Node.js SDK for BlindPay - Stablecoin API for global payments.

Installation

npm install @blindpay/node
# or
yarn add @blindpay/node
# or
pnpm add @blindpay/node
# or
bun add @blindpay/node

Authentication

To get started, you will need both your API key and your instance id, you can obtain your API key and instance id from the BlindPay dashboard https://app.blindpay.com/instances/{instanceId}/api-keys

import { BlindPay } from '@blindpay/node';

const blindpay = new BlindPay({
    apiKey: 'your-api-key-here',
    instanceId: 'your-instance-id-here'
  })

[!NOTE]
All api calls are going to use the provided api key and instance id

Quick Start

Check for available rails

async function getAvailableRails() {
    const blindpay = new BlindPay({
      apiKey: 'your-api-key-here',
      instanceId: 'your-instance-id-here'
    });

    const { data, error } = await blindpay.available.getRails();
    
    if (error) {
        throw new Error(error.message)
    }
    
    console.log('Rails: ', data)
 }

 getAvailableRails()

Response format

All API methods return a consistent response format

Success response

{
  data: /* your data */ ,
  error: null
}

Error response

{
  data: null,
  error: {
    message: "Error message"
  }
}

Error handling

This SDK uses a consistent error handling pattern. Always check for errors:

const { data, error } = await blindpay.payins.list();

if (error) {
  // error.code is a stable code (e.g. PAYOUTS_INSUFFICIENT_BALANCE); error.description is
  // safe to show to end users; include error.trace_id when contacting support.
  console.error('API Error:', error.code ?? error.message);
  return;
}

console.log('Success:', data); // fully typed

Safe retries (idempotency)

Every method that creates, updates or deletes something takes an optional last argument. Pass an idempotencyKey and a retry with the same key and the same input replays the original response instead of acting twice, for example when a timeout leaves you unsure whether a payout was created. Keys are kept for 24 hours.

import { randomUUID } from 'node:crypto';

const idempotencyKey = randomUUID(); // reuse it only to retry this same call

const { data, error } = await blindpay.payouts.createEvm(
  { quote_id: 'qu_000000000000', sender_wallet_address: '0x...' },
  { idempotencyKey }
);

Webhooks

constructWebhookEvent verifies the Svix signature and returns the payload typed by its webhook_event. It throws a BlindPayError when verification fails. Pass the raw request body, not a re-serialized object.

const event = blindpay.constructWebhookEvent({
  secret: process.env.BLINDPAY_WEBHOOK_SECRET as string,
  headers: {
    id: req.headers['svix-id'] as string,
    timestamp: req.headers['svix-timestamp'] as string,
    signature: req.headers['svix-signature'] as string,
  },
  payload: rawBody,
});

switch (event.webhook_event) {
  case 'tos.accept':
    console.log('ToS accepted:', event.tos_id);
    break;
  case 'customer.update':
    console.log('KYC status:', event.kyc_status);
    break;
}

verifyWebhookSignature is still available when you only need a boolean.
