5:06 Shouldn't you need to check the "Auto-refresh the token before it expires." option ?

[@ShivShankar000]

a small advice to friends. at 4.50 it was not working as shown in video. so i added a new redirect uri same uri but remove last / sign. And Thanks Sir. It helped

Dear Melvin, thank you for this great video. May i ask you a question? This setup seems to work only for developing. Since i have published the app as you suggested, i get this epic "invalid grant" error from production backend, whereas in development everything works fine. Do you have any idea, what to do? I would appreciate it very much. Cheers, Marc

[@cdexzswzaqME]

did you figure out how to solve this issue

[@Marc1920x1080p]

@@cdexzswzaqME no. Finally i have switched to Mandrill (Mailchimp) Service, which is very reliable for production and works like a charm. Cost about 40$ per month

[@raba650]

If the oath will be used for a contact form to send emails, wouldn’t a service account be more fit in this use case scenario?

[@clepzzz]

Hi RhymBil, I did same steps and achieved to send emails on January 4. However I encountered with "invalid_grant, bad request" error. I achieved to send emails again after generate a new refresh token. Why did this happen? Do I need to generate a new refresh token after some time manually by clicking 'exchange authorization code for tokens' button and then replace new generated refresh token with old?

[@MelvinAdekanye]

Hmm. This is a good question. I also encountered the same issue. But once I got a new token (similar to your situation). I didn't seem to have the issue again. As far as I've experienced, it's only happened once, but definitely a question I'm going to have to look into. Thanks for the great question.

[@NITHINPB]

@@MelvinAdekanye Hey, did you get time to look into this ? i am implementing this and it works fine now. But i am exprecting this error soon, since refresh_token has an expiry

First of all thank you very much dude! You are awesome. It works almost perfectly for me. Somehow it sends two emails. One with the expected message and subject etc, and another one with nothing in it? Anyone else is having this issue?

[@MelvinAdekanye]

You're most welcome! That's interesting. Do you have your code in a loop? Or duplicated? If no, add console.log() where you have your send function, to see if it logs twice.

Did you publish/make public your Google API? If you leave it in test mode, you'll have to update the tokens every now and then.

Yes! While the testing mode is great. It's simply just that, a means to test (with time limitations). Switching to "production mode" will take away those testing time constraints. And you're right. It should work.
