Authorization request - The redirect_uri does NOT have state upon return.

[Guest]

 Hi there,

Would you know why the return URL after authenticating will be missing a 'state' query string "http://localhost:4200/callback-loader?code=GB%2F8afd163f-884e-47bb-b59d-f0a08794ff41&country=GB" 

I am definitely sending the state on my callback URL and it looks like this, of course I changed the Client ID:

"https://www.sageone.com/oauth2/auth/central?filter=apiv3.1&client_id=myclientId9&response_type=code&redirect_uri=http%3a%2f%2flocalhost%3a4200%2fcallback-loader%3fscope%3dfull_access%26state%3d%7b%22Username%22%3a%22siphomaribo%40myscooter.co.za%22%2c%22AccountingSystemTypeId%22%3a%22550e8400-e29b-41d4-a716-446655440000%22%7d"

There surely is something wrong that I am doing?

Hi Sipho,

I'm not sure I understand your issue and what it is you are expecting in the response? Are you following the auth guide https://developer.sage.com/accounting/guides/authenticating/authentication/. Could you reference in the guide what you are expecting?

The flow is - You send the auth request with the scope and then the redirect takes the user to the sign in. There they will be asked to grant access to the connecting application. If the scope was passed they would see read_only or full_access when they grant the connecting application access.

Once they have granted access the auth_code will be returned to your callback URL and then you exchange the auth_code for a set of tokens. On successful exchange tokens will be retuned for the access an refresh tokens. I've included an access token response below which includes the scope.
 

{
    "access_token": "eyJhbKXQF-nHPIualmhB9QeRhqChs9jMOPtQv3md40eB1KY_SjfwhPCoWkwxZla9DVAgUf2aVKhw_cw3Rr6e1AjT8DrLlz-59IsC_QkibG0QsVkiolKAXljvogCIZacMSpKM4U2H5nDJzkNnHKXZhXQQJEwX5oh8dY4AN-jaucmRIL8XUi5NII1PbFHH-qMPCfQujs0stH3NUfTtSjk7-A4RAI3EwUvOxM2O_G8dz3nSa2yzLumwzDa7gFQeg3sZRbES3wnS_wW122S4DP6OHCkwcUy9MCs6XZlTjZ4sO1dyHHzeFRlxZbLwUE4yPJiIqJEF-Bs7veyL0RoNPYZXMdAVB6kvnfrprEJRL8ogJvPiocApQIM9eO-FDd6LADM",

    "scope": "full_access",
    "requested_by_id": "2b486e58-632a-a6cd-6ea8-eb5183931ad3"
}

Hi @Steel, Mark thank you for reaching out. 

Yes, I am following the documentation and on the documentation, there is a query param called "state", according to the documentation, when the callback happens, it should contain THREE query params code, country and the state, but it only contains the code and the country not the state. I use state for validation and if it's null, my code falls over.

Finally figured this out. I was attending the 'state' value in my redirect url instead the Sage url.

Thanks Sipho,

I'd been looking into why this wasn't being returned but could not replicate.

Thanks
