This is additional info concerning my Yahoo error message problem. Below is the info that was generated when I ran a diagnostic test (in the diagnostic info below, I changed my real username to ADMIN_USERNAME for safety reason, since this post will become public):

make sure when creating the Yahoo client ID that you select to use the Mail API.

Thanks so much for your speedy response. Actually, I used the Mail API option.

I just tried a test myself and it works fine (sometimes Yahoo goes down).

1. I logged in to Yahoo with the same account I configured in Postman.
2. I used my site’s test domain (wp.mydomain.com) as the callback – a real name, not an IP address.
3. I enabled Mail API – Read/Write
4. I copied the generated Client ID/Client Secret into Postman
5. I performed the Grant. Bam, done.
6. I sent a Postman test email

Maybe delete your Yahoo Developer App and start over?

Jason, I am happy to report success. Here’s what I just did: I put in the two hyphens at the end of the Client-ID just like it was displayed to me when I set it up and grant-permission-to-yahoo worked. But what baffles me is that it had failed with and without the hyphen yesterday. I have sent myself a test email which arrived.

on a personal level, let me thank you very much for your time and selfless help. I really truly appreciate that. Will try and connect with you via your website codingmonkey.

You’re very welcome.
