URI's

Hello,

I’m a little confused about what I should be entering for the URL and the Redirect URI(s). Can you please provide clarification on this? I’ve tried almost every variation I can think of with no luck.

Error:

OAuth Error: redirect_uri did not match any configured URIs.

Passed URI : http://ourwordpressinstallation/wp-admin/options-general.php?page=slack-for-wordpress

Allowed URI : https://ourwordpressinstallation

Thanks,
Rich
