[fit_rewards]

I'm having issue verifying an endpoint "https://fit-uat.muangthai.co.th/api/v1/fitbit-service/fitbit/activities"

there is no requests from Fitbit when i click "Verify"

the endpoint is accessible from internet and working fine on web browsers

client id : 23Q388

Hi @fit_rewards 

Thanks for reaching out! To help us understand the issue better, could you please try the verification steps in the OAuth tutorial ?
If you encounter any errors during this test, please let us know at which specific step the error occurs. Additionally, providing error codes and a screenshot of the error message would be greatly appreciated. This information will allow us to diagnose the problem more effectively.

Hi @fit_rewards 

We see you have 2 subscribers with the same URL.   I'd recommend changing one of them to a different URL, such as ".../fitbit/revoke/".  Also, I see in our logs that when we try to send you the verification codes we are getting a 403 in response from your endpoint.   Would you please double-check your code and security?
