Revoke a grant request

Esta página aún no está disponible en tu idioma.

If an authorized client no longer needs access to protected resources, the client can revoke the corresponding grant request.

These code snippets enable a client to revoke (cancel) a grant that it was previously issued. When a grant request is revoked, the request is placed into a finalized state and no further updates to the grant are allowed.

Before you begin

We recommend creating a wallet account on the test wallet. Creating an account allows you to test your client against the Open Payments APIs by using an ILP-enabled wallet funded with play money.

Revoke a grant request

Initial configuration

If you’re using JavaScript, only do the first step.

Add "type": "module" to package.json.

Add the following to tsconfig.json

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "ES2022"
  }
}

// Import dependencies
import { createAuthenticatedClient } from '@interledger/open-payments'

// Initialize client
const client = await createAuthenticatedClient({
  walletAddressUrl: WALLET_ADDRESS,
  privateKey: PRIVATE_KEY_PATH,
  keyId: KEY_ID
})

// Revoke grant
await client.grant.cancel({
  accessToken: CONTINUE_ACCESS_TOKEN,
  url: CONTINUE_URI
})
