Notifications

Webhook Notification

Introduction

This section covers how webhooks are used to notify about events that happen in SmartPay. Some events, like transaction status change, are not the result of a direct API request. Webhooks solve these problem by letting you provide a URL to which we will send a notification anytime such an event happens. The "Notification Target URL" will receive a JSON payload depending on the notification type. Based on your integration requirements the notification service has to be turned on. Please contact Customer Support to check your setup configuration.

Authentication Options

Based on the security requirements of the merchant website, the following authentication options are available:

Authentication TypeBehavior
No AuthenticationThe webhook request is sent without any authentication information.
Basic AuthenticationThe webhook request includes a username and password encoded in the HTTP headers. Please provide your username and password to us.
OAuthThe webhook request uses OAuth tokens for authentication. Please provide the OAuth provider URL, ClientID, and ClientSecret to us.

Notification Format

The "Notification Target URL" will receive a JSON payload respecting the below form

List of the available notifications

objectTypeoriginDescription
payment"automated"Created every time when SmartPay payment transaction status gets changed. Useful for tracking the statuses of asynchronously processed payments or payment modifications initiated not through the SmartPay API, e.g from Merchant Panel. For security reasons only transaction id is provided into the notification body. To get the actual payment status Get Payment Status API should be used. As a 'transactionId' value required by Get Payment Status API use 'id' value received in notification.

Example payment notification:

{
"id": "c200b3fd-4960-4cd8-918c-5919013ce769",
"createdAt": "2021-10-01T08:42:28.637Z",
"origin": "automated",
"eventType": "status.updated",
"objectId": "c200b3fd-4960-4cd8-918c-5919013ce769",
"objectType": "payment"
}
objectTypeoriginDescription
refund"automated"Created every time when SmartPay refund status gets changed. Useful for tracking the statuses of asynchronously processed refunds or refunds initiated not through the SmartPay API, e.g from Merchant Panel. For security reasons actual refund status is not provided in the notification data, only refund and transaction identifiers are provided in 'objectId' 'id' fields respectively. To get the actual refund status use Get Payment Status API to retrieve transaction status and all modifications made to it by passing 'id' value provided as 'transactionId'. To determine the refund which has triggered the notification get first modification element with 'modificationData'/'type' equal to 'REFUND' and 'modificationData'/'refundId' equal to 'objectId' value received in notification. Read 'status' value from the found modification element for actual refund status.

Example: Refund notification:

{
"id": "c200b3fd-4960-4cd8-918c-5919013ce769",
"createdAt": "2021-10-01T08:42:28.637Z",
"origin": "automated",

"objectId": "4f6e528d-1438-43ee-9835-a17c05c34429",
