Self Published C2C integration not showing up on Android Mobile App


I have created a simple C2C Integration using the webhook Connector.
I have self published on

Currently my API only implements the Ping because I am trying to inspect the other messages my server receives.
Thus far I only receive the Ping Message.

When I go to the Mobile app and try to add my device I can’t see it.

The Instructions on this Github say:

On the Devices page of the SmartThings mobile app tap ADD DEVICES, tap ADD DEVICE MANUALLY and then select your device from My Testing Devices at the bottom of the page


Have you reached out to the developer support via ?

I haven’t but I’ll give it a try.
