Response Handling

When responding to successful processing of our messages, the consumer should return an OK HTTP response: HTTP/1.1 200 OK

Any other response will be interpreted as a failure in handling the message on the consumer side and will be queued up to try again later.

EPS enforces a timeout defaulted to 5 seconds. It is possible that the message is delivered but exceeds this timeout on EPS side. This message will be queued up to try again later. You can use the hash value as a key identifier for duplicate checking.
