RESt API attachment timeout over 300s

[Marcel Caceres]

I have a big file in sys_attachments that I am trying to retrieve with a REST API call to the Attachment API. The file is 279MB

I increased the API Attachment Request timeout from the default 60 seconds to 360s just to allow this file going out.

However, the transaction is timing out at 300s (and 254MB)

Is there a known reason why the 360s timeout I set is not being respected? Is there another timeout with higher priority set at 300s?

Not sure if this is the same issue, but we had something similar happen and found the REST and JSON Catch All Transaction Quota Rule that needed to be increased.

You can check that by going to System Definition => Transaction Quota Rules  and looking for the above rule.

This is the correct answer. Thanks!
