I’m currently proxying all requests to Amplitude via an API gateway. This prevents me from using the Amplitude Event Explorer.
To work around this problem, I’m copying the extension, inserting my custom end point into the extension source code, and then manually loading the extension so it detects my events. This is a chore. If I wanted to share this with my co-workers, I’d have to publish my own copy of the extension which might not line up with the terms of use.
If the extension were open source, I might be tempted to fix this myself. :-)
