Gmail - Error 400: redirect_uri_mismatch

[Kris2066]

I followed the directions - enabled API, etc. and got secret keys. Enter them in Fluent SMTP screen and when I go to authenticate with google and get token, Google is saying "Error 400: redirect_uri_mismatch".

The redirect URI prefills on my Fluent screen as ""https://fluentsmtp.com/gapi/"

I have authorized Google accounts for other programs, am quite sure I have everything set correctly .

Can someone assist?

Same thing happening to me. Did you ever find a solution?

I was finally able to figure it out. Don't know if this will fix your issue but I had selected Desktop (per the instructions i the tutorial video) but in the documents, it says select Web app and this worked. Hope this helps
