Using Master Token with _uid in api/v2 vs api/v3

[shamkim]

Not sure if this was documented anywhere (couldn't find it in search) but thought I'd bring it up just in case. I've been trying to use the api to post topics using a _uid and master token in the api/v3 route and I kept getting forbidden errors. decided to try api/v2 and it works just fine now. I'm on the latest version of nodebb

Can you share a lot more detail? Request and response body and headers, endpoints, etc. If you can, share code.
