Sorry, that page is following a different trail.

[reeder32]

I am using the web api oauth2.0 to verify user login, and then using a token to make api calls to get activity data in my ios app. I haven't made any changes in over a year, but I started getting some negative reviews from users who were unable to login/sync fitbit. Even when I use the fitbit api debug tool, I get the same page, which is essentially a 404, that is telling user "Sorry that page is following a different trail"

Here is the example of my url string 

NSString *urlString = [NSString stringWithFormat:@"https://www.fitbit.com/oauth2/authorize?response_type=token&client_id=%@&redirect_uri=%@&scope=activity&expires_in=31536000", fitBitClientId, redirectUri];

I am using a safari view controller to open the log in page. I have verified the redicrectUri works.

Any ideas/fixes will be greatly appreciated. Thanks.

Would you mind posting your redirect_uri value?

WalkAgainstHumanity://

I think your problem is the redirect/callback URL is not absolute

In the OAuth 2.0 Authorization Framework spec, section 3.1.2 states  The redirection endpoint URI MUST be an absolute URI as defined by

[RFC3986] Section 4.3.  The endpoint URI MAY include an

"application/x-www-form-urlencoded" formatted (per Appendix B) query

component ([RFC3986] Section 3.4), which MUST be retained when adding

additional query parameters.  The endpoint URI MUST NOT include a

fragment component.

RFC3986 Section 4.3 defines the absolute URI to be

        absolute-URI  = scheme ":" hier-part [ "?" query ]

I've seen various errors displayed because the redirect URL being used is not absolute.   Try changing your redirect URL from WalkAgainstHumanity:// to a specific entry point in your application (i.e. WalkAgainstHumanity://callback)

Okay. I’ll try this and let you know how it goes. I’m the meantime, was this a change in the sdk? It has worked for over a year, but just last month or so is when I started getting feedback from users that it wasn’t working.

Hi @subscription 

At what point in the authorization process do you receive the error "Sorry, that page is following a different trail"?

Why am I getting this on my screen when I type in Fitbit.com/setup

It seems that some country-specific versions of that page may have issues (see here).
