URL couldn’t be validated

Hi, and thank you for this plugin.

I’ve just installed it and I’m setting it up a facebook app.

I’ve entered the callback url as: https://www.MYDOMAIN.com/mbot-callback-webhook/

and then added a string to the ‘verify token’ field as: my_voice_is_my_password_verify_me

(I’m guessing this string can be anything?

When I hit ‘verify and save’, I get a red ‘x’ and a note that reads, “URL couldn’t be validated’.

I searched the FAQs and followed the step to re-save permalinks in my WP settings.

In the Woocommerce settings under ‘Messenger Bot’ > ‘API SETTINGS’, I’ve left Page ID, Messenger app ID, and Page Token blank but entered the same string as above for the ‘verify token’ field.

Not sure what I’m doing wrong.

I appreciate your help!
