Overview

Webhooks are HTTP callbacks that deliver notification messages for events. Peach Payments uses webhooks to inform merchant systems when certain events occur. This way, your servers are always up to date with transaction information.

After configuring and verifying a webhook, Peach Payments delivers POST notifications to the specified URL for the following events:

Webhook event	Description
`initiated`	Triggered when you create the payment link.
`opened`	Triggered when a customer opens the payment link.
`processing`	Triggered when a customer attempts to pay.
`completed`	Triggered when a customer completes the payment.
`cancelled`	Triggered when a customer cancels the payment.
`expired`	Triggered when the payment link expires.

For bulk payment links, Peach Payments sends webhooks for the underlying payment links and for the following batch events:

Webhook event	Description
`initiated`	Triggered when you create the batch.
`processing`	Triggered when processing starts on the bulk file.
`completed`	Triggered when Payment Links completes processing of the bulk file.
`error`	Triggered if Payment Links cannot process the bulk file.
`expired`	Triggered if you do not upload a file in three hours.

Flow

Merchants can configure webhooks in one of two ways:

Enter a webhook URL in the notificationUrl parameter of the options object of the generate link request or in the notificationUrl parameter of the generate bulk link request.
Register a webhook URL in the Peach Payments Dashboard.

Predefined events, as described above, trigger the webhook.

The merchant receives a webhook with a result code indicating the updated checkout status.
The merchant returns a 200 status code response acknowledging the webhook.

The merchant can then trigger a query to pull transaction or batch details and statuses.

Webhook retry mechanism

Peach Payments expects a 200 HTTP for successful webhook delivery and a non-200 HTTP status code for failures.

For an unsuccessful response, Peach Payments retries the webhook for 30 days or until a successful acknowledgement (200 HTTP) occurs.

Exponential backoff retry

Below is the exponential backoff logic.

The interval between retries is:

2 minutes
4 minutes
8 minutes
15 minutes
30 minutes
1 hour, every day until 30 days have passed since the first attempt
