Hi everyone.
Thanks for all your comments about this inconvenience with your friend requests. Please confirm that the Fitbit app on your phone is running the latest app version: Fitbit app 3.69. If you're using a Pixel Watch, uninstall and reinstall the Fitbit app on your phone.
After updating the Fitbit app, I'd recommend trying to send a friend request with these instructions:
Please check with your friend to determine if he received your friend request. Ask your friend to also check Spam folder just in case.
If you're still receiving 'Error 403' when sending a friend request:
See you around.

Best AnswerWhen I try to add friends from Facebook and searching via user name, I get the error message "Failed to Send Friend Request [ERROR 403] [URL https://android-cdn-api.fitbit.com/1.1/user/-/friends/invitations]
How do I get this resolved?

Hi @GlennHad,
Welcome to the forums!
It looks like we don't support adding Facebook friends through the Web API. Using the POST Invite Friend endpoint, you can only send invites to friends using their UserId or UserEmail.
I hope this helps. Let me know if you have any additional questions.

@Elwould Can you provide me with the full URL you are calling so that I can check if it is being formatted correctly? I've tested the Invite Friend endpoint on my end and I received a 201 response code, which indicates a successful query.
Hope to hear from you soon!
This is the error I get everytime I send one out whether it be by contact, email, username, or Facebook
Failed to Send Friend Request
[ERROR 403] [URL https://android-cdn-api.fitbit.com/1.1/user/-/friends/invitations]
Same thing happening to me as well, it doesn't matter how I try to invite I still get error code
I'm getting the same message. I'm trying to connect with their iCloud email account ☹

Welcome to the forums!
Can one (or both) of you provide me with a screenshot of the error you are seeing? This is beginning to sound like an issue with the application itself, not the actual API for inviting friends. If this is the case, I may need to move this thread to the appropriate forum.
Thanks!

I am having the same issue as many others - I've not seen a solution yet.
I get a 403 error when I try to add a friend. It occurs no matter whether I try to add them from contact list, from facebook friend list, or by email. I have already tried logging out, deleted the app and reinstalled it. I still get the same message when trying to add a friend. Is there a fix?
