End-to-end verification

Follow this sequence to verify your integration:
1

Generate a key pair

Use the instructions in Key Generation.
2

Register the merchant

Provide your public key to Blink (Merchant Registration).
3

Configure your signer

Set the private key and merchant ID on your signer endpoint.
4

Launch the deposit flow

Call requestDeposit() from your app.
5

Complete a test payment

Walk through the hosted flow iframe to complete a payment.
6

Verify the result

The DepositResult should contain a transfer.id and transfer.status.

​
Staging environment

For staging and shared environments:
  • Deploy your signer as a server endpoint or serverless function (e.g., AWS Lambda).
  • Store the private key in a secrets manager (e.g., AWS Secrets Manager).
  • Point the Deposit SDK’s signer config at your deployed signer URL.
  • Set webviewBaseUrl to the Blink staging URL: https://pay-staging.tryblink.xyz.
const deposit = new Deposit({
  signer: 'https://your-staging-api.example.com/api/sign-payment',
  webviewBaseUrl: 'https://pay-staging.tryblink.xyz',
});

​
Debug mode

Enable debug logging to trace the full SDK lifecycle during development: 
const deposit = new Deposit({
  signer: '/api/sign-payment',
  debug: true,
});
This logs signer calls, iframe state transitions, postMessage events, and errors to console.debug with the [BlinkDeposit] prefix.
