If you are using automatic scaling <https://cloud.google.com/appengine/docs/go/modules/#automatic_scaling_1> (the default) on App Engine, requests <https://cloud.google.com/appengine/docs/go/requests> are limited to a maximum of 60 seconds. This is because these instances are optimized for short lived user requests.
If you need a longer timeout you can 1) use a task queue as a. Kong suggested which can run for up to 10 minutes or 2) switch to manual scaling <https://cloud.google.com/appengine/docs/go/modules/#manual_scaling_1> which can run any kind of request for up to 24 hours. Probably in your case you want to use a task queue, since you can just kick off the task and return success to the user immediately without waiting for processing to finish first.
