The Authified API itself is capable to post back some of the data to a webhook on different events for client's profile only if a valid webhook URL is already setup on merchant account.
Authified API will add data to a queue immediately after the event fired and will try to post back data to provided webhook URL. The data will remain in queue until received a successful (200 OK) response from webhook server. After first time receiving un-successful response from webhook server, the system will try to post back data 4 times after every 30 minutes. After 5 times of try in total, the system dequeue the data and job will be deleted. See webhook events or testing
