Authentication in shinyapps.io

[Eflores89]

Hi, I am building an application hosted on shinyapps.io that sends an email. When running locally it works using use_secret_file however, this authentication does not seem to work on server in shinyapps.io (I upload the json file as well).

The error log indicates the following:
Please point your browser to the following url: https://accounts.google.com/o/oauth2/auth?scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fgmail.readonly%20https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fgmail.modify%20https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fgmail.compose%20https%3A%2F%2Fmail.google.com%2F&redirect_uri=http%3A%2F%2Flocalhost%3A1410%2F&response_type=code&state=BMX5xxbBjG

So it seems to not be using the file. Is there something I am missing in the way it is called inside the shiny session? Or any thoughts on how I can achieve this authentication? It seems to work fine with googlesheets (using gs_auth )

The json file contains just the client id and secret, I believe, not an actual token. So you still need to make provision for an actual token on shinyapps.io. Presumably this is being stored in a .httr-oauth file locally and that needs to go with your app as well. Note that there are some security concerns with this. All will probably be fine, but I doubt shinyapps.io was built to be super protective of your source files.

Ok I see, sorry to hassle but I can't seem to get it to work.

I have tried leaving the httr-oauth file in the directory, reading it in and using the "service option",

googleAuthR::gar_auth_service(json_file = "www/consulting-send-app-b4d8ece8370a.json", 
                              scope = "https://www.googleapis.com/auth/gmail.send")

But nothing seems to be working.

I am doing another authentication in the same shiny app for googlesheets using gs_auth, might that have an effect? Any ideas?

I'm afraid I'm not up to speed on googleAuthR. It sounds like you're trying to use googlesheets, gmailR, and maybe some other google service, all in one app? I suspect gmailR requires or strongly suggests having its token in .httr-oauth. googlesheets has a way to store/retrieve token from an arbitrary .rds file (explained in vignette: https://cran.r-project.org/web/packages/googlesheets/vignettes/managing-auth-tokens.html). So gmailr and googlesheets shouldn't get in each other's way. Not sure where googleAuthR fits in.
