App Authentication

Hi,

I have a question regarding authentication types. I tried to use App Authentication, but it seems that this method does not work with the v2 API.

According to the documentation (https://www.dropbox.com/developers/reference/auth-types), /1/metadata/link acts as the endpoint for App Authentication, which is a v1 endpoint. The API v2 version of this endpoint is /2/sharing/get_shared_link_metadata, but it is stated in the forum that this does not support App Authentication (https://www.dropboxforum.com/t5/API-Support-Feedback/Invalid-request-No-auth-function-available-for-given-request/td-p/208360).

Am I correct in concluding that App Authentication is not possible with the v2 API?

Thanks in advance

While the API v2 infrastructure itself does implement app authentication as one of the authentication types, it is supported (or not) on an endpoint-by-endpoint basis.

Currently the API v2 /2/sharing/get_shared_link_metadata endpoint unfortunately does not support app authentication. (You can check which authentication type(s) an endpoint currently supports in the "AUTHENTICATION" section of the documentation for that endpoint. For example, /2/sharing/get_shared_link_metadata currently only supports "User Authentication". For comparison, the only API v2 endpoint that currently supports app authentication is /2/auth/token/from_oauth1.)

I'll pass this along as a feature request for app authentication support for /2/sharing/get_shared_link_metadata. I can't promise if or when that might be implemented though.
