Webhook Notifications

Set up webhooks to get real-time updates on events within the API.

Acquired.com uses webhooks to notify your application when events occur, such as, the final status of the payment is known. We deliver webhook notifications to the URI endpoint configured in the Hub. A webhook is an automatic notification that we can send directly to your system after an event takes place against your account. Webhooks are server to server notifications unaffected by potential issues with the front end system and user error.



If your firewall blocks incoming requests, you might need to add our IP addresses to allow you to receive webhooks.

Webhook structure

Each webhook may contain the following headers:

Content-TypestringThe media type of the resource: application/json
Company-IdstringThe Company ID associated with the event.
MidstringThe Mid ID associated with the event. (not required for customer_new and card_new)
Webhook-VersionstringThe version of the webhook body schema.
HashstringThe calculated hash value.

The webhook body may contain the following parameters:

Webhook retry policy

We consider a webhook as having been successfully delivered when we receive a HTTP status code 200 from your webhook URI.

If we do not receive a 200 success status response code then we will start retrying. Our retry logic will resend the notification every 5 minutes until a 200 status code is returned. If we do not receive a 200 status code after 25 minutes, we will discard the webhook.

Configuring webhooks

Webhooks can be configured from within the Hub, you select the webhook events that are required and define the URL(s) that are to be targeted.

  1. Firstly, go to Settings menu and from the Company tab select Webhooks.
  2. Enter the URL to be targeted when sending webhook notifications.
  3. From the drop-down list select the events that you want to trigger the notifications. (You can select multiple at a time). If you select status_update the statuses returned are displayed here.



For Hosted Checkout and Pay by Bank set up, please refer to the relevant guides.
