Instagram access token request returns 400 Bad Request

[Rixot]

Hi,

I'm using this library for a number of services including Instagram, but I'm having trouble with Instagram and requestAccessToken():

file_get_contents(https://api.instagram.com/oauth/access_token): failed to open stream: HTTP request failed! HTTP/1.1 400 BAD REQUEST on line 73 in [...]/vendor/lusitanian/oauth/src/OAuth/Common/Http/Client/StreamClient.php

As far as I can tell, the request body is correct:

'code' => string 'f47258f0ad064abda528c127af1a47ed' (length=32)
'client_id' => string '(( client id ))' (length=32)
'client_secret' => string '(( client secret ))' (length=32)
'redirect_uri' => string '(( redirect uri ))' (length=151)
'grant_type' => string 'authorization_code' (length=18)

The client ID, client secret and redirect URI are all correct and match the application credentials. I know the HTTP client in this library also defaults to making POST requests, so as far as I can tell, I'm doing everything correctly and the workflow matches the one outlined in the Instagram docs.

Note that I have a working implementation of Twitter auth using the same library in the same project. Both are handled by the same class method, which I based on the examples:

if (!empty($_GET['oauth_token'])) {
    // OAuth 1 assumed; an extra step is required to obtain the access token
    $token = $this->storage->retrieveAccessToken($service);
    $service->requestAccessToken(
        $_GET['oauth_token'],
        $_GET['oauth_verifier'],
        $token->getRequestTokenSecret()
    );
} elseif (!empty($_GET['code'])) {
    // OAuth 2 assumed; obtain the access token
    $state = isset($_GET['state']) ? $_GET['state'] : null;
    $service->requestAccessToken($_GET['code'], $state);
}

Any ideas?

Which version of this library are you using?

Late reply, but maybe it will help others. The cause is probably invalid settings of credentials (if you based on example)

$credentials = new Credentials(
    $servicesCredentials['instagram']['key'],
    $servicesCredentials['instagram']['secret'],
    '<ABSOLUTE_URI>' // $currentUri->getAbsoluteUri() add GET params and that is causing this problem
);

so replace $currentUri->getAbsoluteUri() with EXACT uri as you configured in your application and it should work.

I am actually having this problem as well on Instagram only, and tried using the absolute URI. Getting the same error as the OP.

$credentials = new Credentials(
        getenv('INSTAGRAM_APP_KEY'),
        getenv('INSTAGRAM_APP_SECRET'),
        getenv('INSTAGRAM_ABSOLUTE_URI')
    );

Edit This was mostly likely to a bug on instagram for the past 24 hours. Seems fixed.
