To configure webhooks: Make an API call: PUT https://api.sandbox.cleeng.com/3.1/webhook_subscriptions/{topic}
Replace {topic} with the topic you want to subscribe to (i.e. the event you want to be notified about), e.g. subscriptionReadyForPaymentAuthorisation. A topic identifies what event has occurred in the Cleeng system.
Provide a list of endpoints to which notifications should be delivered.
No matter what connector you choose, you should apply the webhook filtering logic - filtering by paymentMethodId. This allows you to differentiate transactions coming from the respective connectors.
IMPORTANT: You have to repeat the configuration steps for each required topic.
WARNING: Be careful not to override the webhooks you have already subscribed to as the PUT method creates a new resource or replaces a representation of the target resource with the request message payload.
