A 403 "Developer Inactive" error is received when trying to post to the access_token endpoint in the UnderArmour Connected Fitness api. The client_id being used is active. The url used in the call is: https://api.ua.com/v7.1/oauth2/access_token/
This is a snippet of the call using python, after having obtained the authorization code:
import requests
access_token_url = 'https://api.ua.com/v7.1/oauth2/access_token/'
access_token_data = {'grant_type': 'authorization_code',
'client_id': CLIENT_ID,
'client_secret': CLIENT_SECRET,
'code': authorize_code}
response = requests.post(url=access_token_url, data=access_token_data)
In [24]: response
Out[24]: <Response [403]>
In [25]: response.content
Out[25]: '<h1>Developer Inactive</h1>'
where CLIENT_ID and CLIENT_SECRET are my registered values on the developer's portal.
