I followed this link OAuth 2.0 In .NET With Instagram API, and it helped me fix my issue with getting my access token.
My code is this:
NameValueCollection parameters = new NameValueCollection
{
{"client_id", ClientId},
{"client_secret", ClientSecretId},
{"object", "user"},
{"aspect", "media"},
{"verify_token", "thisIsANormalSubscription"},
{"callback_url", CallbackURI}
};
WebClient client = new WebClient();
var result = client.UploadValues(SubscriptionURI, parameters);
SubscriptionURI = "https://api.instagram.com/v1/subscriptions".
I'm following the guide from instagram(http://instagram.com/developer/realtime/) including all the parameters for the POST request. But I only get the 400 error when it does the client.UploadValues.
PS:This is my first post, so might not be as appealing for the eye as I would wish
