Guidance for UNAUTHORIZED_ACCESS issues



Recently, there have been several forum topics around UNAUTHORIZED_ACCESS. Some examples include:

As this post states:

If you receive a 401 UNAUTHORIZED_ACCESS, the likely cause is that your authentication credentials were missing or incorrect.

We strongly recommend using twurl:

Twurl is like curl, but tailored specifically for the Twitter API. It knows how to grant an access token to a client application for a specified user and then sign all requests with that access token.

Once you are able to successfully make the request using twurl, you can be fairly certain that there was an issue with your authentication credentials and not with access to the Ads API. If you need further assistance, please visit the OAuth category.

ADS API "UNAUTHORIZED_CLIENT_APPLICATION The client application making this request does not have access to this API"
Still can't access Ads API
Unable to use start and end time while querying the API
UNAUTHORIZED_ACCESS - This request is not properly authenticated



If you’re seeing UNAUTHORIZED_ACCESS issues with the stats endpoints (e.g., GET stats/accounts/:account_id), please see this post.
