Webhooks are requests from our servers to an HTTPS endpoint of your choice sent when certain events have occurred on your account.
These requests POST an event object containing a data payload for the triggering action to an endpoint URL of your choosing.
Webhooks allow for you to be asynchronously notified when important events have occurred (e.g. the completion of a charge).
You can use different URLs for test or live mode. You can add or update your test mode endpoint by visiting https://dashboard.omise.co/test/webhooks.
All event data can be found in the dashboard under Events
or via the Events API.
Serialization
The event object in the POST request (or returned via the Events API) will always be serialized according to the default API Version as of the event regardless of the value of the Omise-Version header sent in the triggering event.
So, for an account set at 2017-11-02, a charge created using curl passing -H "Omise-Version: 2019-05-29", will generate an event (charge.create) with an embedded charge object serialized according to version 2017-11-02 of the Charge API not version 2019-05-29.
Later, after updating to version 2019-05-29, the embedded charge object for this particular event will still be serialized according to version 2017-11-02.
Requirements & best practices
The URL must be HTTPS and must use a valid SSL certificate, not a self-signed certificate.
You can visit letsencrypt.org for a free SSL certificate for your endpoint and verify it using SSL test.
We recommend that merchants verify the event on webhook receipt to ensure that the status update is authentic.
For instance, if you received a charge.complete webhook event, use the Charge ID to make a GET request for that particular charge (e.g. /charges/chrg_test_no1t4tnemucod0e51mo) to independently verify its status.

Dynamic Webhooks
All Opn Payments accounts feature a single configurable static webhook. By default, notifications for all events are sent to this single webhook endpoint.
With the dynamic webhooks feature, you can now pass the webhook_endpoints parameter while creating a charge. Events related to this charge will be sent to the given webhook_endpoints .
When you pass the webhook_endpoints parameter, notifications for all events for the specified charge are sent to webhook_endpoints and not to the static webhook.
If you do not specify the webhook_endpoints parameter when creating the charge, the event notifications are sent to the account’s static webhook.
