Getting started

[lcolladotor]

Hello,

I am probably missing something obvious, but I am having trouble getting started with using gmailr.

• Went to https://cloud.google.com/console#/project
• I created a project, called it "Access-gmailr"
• Opened the project. Then under "APIs & Auth" and in the sub-menu "API" I enabled the Gmail API. That automatically enabled a couple other APIs as shown below.
  
• Then under "APIs & Auth" and in the sub-menu "Credentials" I downloaded the "Compute Engine App Engine" json. Tried using it and got a 400 error.
  
• Also under "APIs & Auth" and in the sub-menu "Credentials" created a new client ID and selected the "service account" option. This didn't work either and lead to another 400 error.
  

So, hm... what am I missing?

I did check that under the "Permissions" menu all the service accounts have the permission to edit. The Gmail API auth page didn't help me either.

Thanks!

Hi there @lcolladotor, apologies for the incomplete answer. I believe part of your issue is when you select the kind of authorization you want from Google. You have to select "installed applications", then Google will give you a json to download.

Before you make your query, though, make sure you authorize the 'Consent screen' under APIs & auth. Without that you'll run into an 401 error.

I hope it helps ...

Hi,

Thank you for the input @luiscape, I got farther this time.

So, under "APIs & Auth", sub-menu "Credentials" I created a new client ID of the "installed applications" type (selecting "other"). Downloaded the new json file and... then got another error.

Steps followed

I made sure to clear the directory before proceeding as shown below.

$ rm .Rapp.history
$ rm .httr-oauth
$ rm .gitignore
$ R

Everything seemed to go fine, as I did get to authorize the app and got the message on the browser saying it was fine.

> library(gmailr)
> gmail_auth("new-installed-applications.json")
Use a local file to cache OAuth access credentials between R sessions?
1: Yes
2: No

Selection: 2
Waiting for authentication in browser...
Press Esc/Ctrl + C to abort

But within 1 second of authorizing the app in the browser, an error popped up in the R console.

Authentication complete.
Error in gmail_auth("new-installed-applications.json") :
  cannot change value of locked binding for 'google_token'
> traceback()
1: gmail_auth("new-installed-applications.json")

Got any tips on what to do now? Seems like it could be related to Binding and Environment Locking.

I can reproduce this, the problem and fix is detailed at http://adv-r.had.co.nz/Environments.html#explicit-envs

The reason that I did not notice this issue when I was developing the package is I was using devtools load_all function, which loads all the objects in the user namespace rather than package namespace. Thank you for reporting the bug.
