OAUTH2.0 GMAIL

[Paul Mulroney]

Hi Martin,

We did this recently for one of our clients.  They use gmail for their primary setup.

In the past, you could use the SMTP settings to send using Gmail's smtp server.  However, they started restricting how that was accessed in a bid to increase security. They then introduced "application specific passwords", which allowed you to create a password for your particular application that allowed you to send using Gmail's smtp server.  I'm not sure if that's an option any longer, I think that was discontinued in the recent past.  The only option to send email via Gmail is using the OAuth method.

To do that, you need to setup some stuff at Google's end to permit OAuth - what you're actually doing is accessing Google's Gmail APIs to send/receive email.  Here's the link to Google's documentation to do this: https://developers.google.com/identity/protocols/oauth2

It's a difficult thing to setup, but here are the basic steps:
- You need a google developer account.  It's been a while since we did this, but think if you have a google account you can just go to console.cloud.google.com <http://console.cloud.google.com/> and it should allow you do setup what you need
- Create a new google project
- Enable the "Gmail API"
- Create credentials - use the OAuth client ID option
-> this will give you a client ID and a client secret

Once you have these, the OAuth example in Omnis will work - you use the client ID and secret, it will ask you to sign into your google account and authorise, then redirect you back to your app.

We had a few false starts and did things out of sequence which required us to start over - 

If this all sounds too hard (and it is!) then you should consider using a mail service like SMTP2Go, or Twillio SendGrid - they allow you to send email via their service.  Again, there will be some setup required, but probably a lot less effort than google!

Regards,
Paul.

Where can I get such a sample library? Or instead, it's just best to store emails in the database and mark them as either sent or pending?
