Bank Transfer Payments Guide (ID)
Customer Profile API
Learn how to use the Payment API to enable Indonesia bank transfer deposits from your user.
Overview
Each connected user on your platform will be assigned a unique virtual account number for bank transfer payments. We check the sender's name against the user's name to ensure the payment is being made to the correct virtual account. This creates a secure and seamless experience for your users and makes it easy for your team to reconcile these transactions.

- To provide payee details for your user, initiate a request to create a virtual bank account to display bank transfer instructions.
- This enables your user to add a payee in their bank app using the fields: bank name, recipient name and bank account number.
Step 2 — Add callback URL
On a successful completion of a deposit transaction, StraitsX will send a callback notification to you via a callback URL indicated on the StraitsX Business Dashboard.

Adding a callback URL in sandbox mode
Add the callback URL on the dashboard to receive callbacks when the transaction has been completed.
Step 3a — Make a mock bank transfer (Sandbox)
curl --location --request PUT 'https://sandbox.xfers.io/api/v3/sandbox/customer_profile/customer_profile_08d5ffe5-8a02-4dc2-aabb-9057b8ab3c65/bank_accounts/?verification_status=verified' \
--header 'X-XFERS-APP-API-KEY: KVBZxX2YVOxlSjbxH0j6Wpc408FJKv88zXHU2aewdyO'
- In the sandbox environment, you can make a mock bank transfer by initiating a mock bank transfer payment.
Step 3b — Make a bank transfer (Production)
To make a bank transfer payment, your users can deposit funds via their bank app.
Step 4 — Confirm deposit has been received
Securing your callback
When the payment is received, we will send a callback to the URL indicated on the StraitsX Business Dashboard. The callback can be decoded using the HMAC-SHA256
algorithm to display the Request Body.
