Getting a 403 Error on Fitbit Subscriber Endpoint – May 22, 2025

[QuangBui]

Hi Fitbit Support team,

I’m encountering a 403 Forbidden error when Fitbit attempts to call the Subscriber endpoint URL, as observed on May 22, 2025. This endpoint is triggered when I sync data from my Fitbit Watch using the Fitbit App.

Could you please confirm if there have been any recent changes on Fitbit’s side that might be causing this issue? Alternatively, do you have any insights into what might be leading to this error?

I’ve attached the relevant request details for your reference.

Thank you for your support.

Best regards,

Quang Bui

Hi @QuangBui 

My apologies for the delay.   Are you still receiving the 403 error when the webhooks are being delivered to your subscriber?   If so, I'll investigation the issue on our end.
