Return a 200 status code quickly
Zoko webhook expects a response from your callback endpoint as an acknowledgement of the message. Expected Response : HTTP 200 OKResponse within : 5 seconds Please note if either of them doesn’t happen, it’s treated as a message delivery failure and retry logic will be executed
What if my processing takes more that 5 seconds?
Because properly acknowledging receipt of the webhook notification is so
important, your endpoint should return a 200 HTTP status code prior to any
complex logic that could cause a timeout.
