Quickstart: First API Call

This guide walks you through authenticating, provisioning credentials in the developer sandbox, and issuing your first request to the Core Banking API.

Step 1: Sign In and Open Developer Console

Navigate to the Developer Console and authenticate via Rook SSO. Select your target Program Tenant (e.g., Universal Banking Sandbox) from the program selector.

Step 2: Create a Developer Application

1. In the console, click New Developer App.
2. Provide an application name (e.g., core-banking-quickstart).
3. Select the Core Banking & Ledger API and Payments & Settlement API products.
4. Click Create App & Generate Keys.

Step 3: Execute an Authenticated Request

Pass your generated Consumer Key in the X-Rook-Api-Key HTTP header:

curl -X GET https://api.sandbox.rookpayments.com/v1/accounts \
  -H "X-Rook-Api-Key: YOUR_CONSUMER_KEY" \
  -H "Accept: application/json"
