New Feature: Balance Webhooks

You can now receive automatic notifications when funds are credited to your IIMMPACT balance, without repeatedly checking the Balance API.

Balance Webhooks send a signed balance.added event for eligible credits, including:

• Bank transfers

• JomPAY balance deposits

Each event includes the amount credited, your balance after the credit, the ledger description, and a unique event ID.

What Can You Do With It?

• Receive an automatic notification when your balance top-up is credited

• View the credited amount and updated balance in your system

• Notify your operations team when funds are received

• Reduce repeated Balance API polling

Secure and Reliable Delivery

Every webhook is signed using HMAC-SHA256. Failed deliveries are retried automatically, and you can inspect delivery logs or replay failed events from the Dashboard.

Because delivery is at least once, use the event id to identify and safely ignore duplicate deliveries.

Get Started

1. Log in to the IIMMPACT Dashboard (https://dashboard.iimmpact.com/).

2. Go to Developer › Webhooks › Balance Webhook.

3. Enter an HTTPS endpoint that accepts POST requests.

4. Register the webhook and securely store the signing secret shown.

Balance Webhooks are optional and available now. They do not trigger for refunds, commissions, balance transfers, or transaction-linked credits.

Read the Balance Webhooks guide for setup instructions, payload details, signature verification, and retry behavior.
