Hi all,

I tried to set up OAUTH in FMS 19.3.1 today but was unable to get it to work.

Here is what I did:

1. **FMS** Went under Administration, clicked "External Authentication", then "Amazon" and "change".

Entered the two credential strings you see when creating a new security profile in your Amazon developer area.

At the bottom of his page, under "Database Sign In", I enabled "External Server Accounts" and "Amazon".

1. **In Amazon Developer website** , under Web Settings, I entered the "Allowed Return URLs" to:

https://_FQDN_/oauth/redirect

(The FQDN matches the private SSL certificate for the site.)

1. **In FileMaker 19.3.1** , I created a new user:

Type: External Server  
Group Name: email address for the amazon account  
Access: Full Access

* * *

Then, when trying to start the FileMaker application to access Amazon, I get a "bad request".

The FileMaker application does come up with an "Amazon" button, but clicking it gives the 400 HTTP error.

The URL https:///oauth/redirect is shown, but I have no idea how that could be the problem.

Any ideas what is wrong?

Thanks very much.

Oliver

Hope someone can help!

Thanks Cecile.  
I got it working by re-creating the security profile. Not sure what was wrong since I just re-created what I had, but it's working now.  
Thanks for the humor. 🙂
