Changing the desired access rights of an application does NOT change the access rights of the access tokens that were already created. After changing the desired access rights of an application, please log into the user's account, click on settings / applications and click on Disable Access of the corresponding application.

Besides missing access rights, 401 Access Denied errors usually stem from invalid signature strings. Please send us the Base Signature String (the string you have one step before encrypting and hashing it with the application secret and access secret) you are generating so that we can compare and quickly locate the issue. Also provide the URL you are sending the request to.
