Medium Problem

Sorry, but what is page=mypagemedium ? Your callback URL must be a SNAP settings page.

https://www.nextscripts.com/instructions/medium-auto-poster-setup-installation/

What is the cannonical construction of the callback URL?

You document it in an image which is hard to copy & paste and the picture suggests that the ‘s’ in NextScripts may not be the last character in the string. I can find no other reference to it.

I am using

https://www.nextscripts.com/wp-admin/options-general.php?page=NextScripts

Can you help?

If you have the default WP installation it should be

https://www.yourdomain.com/wp-admin/options-general.php?page=NextScripts_SNAP.php

That’s fab; the settings are now complete, just need to test a forwarding transaction.

Thank you.
