403 error API method

Hi! I’m trying to use has_membership_access method with Postman.

This is my configuration:

• Url: https://mysite.com/wp-json/pmpro/v1/has_membership_access
  • Params:
    • post_id (found it in the url of the login page on WordPress)
    • email: email of the registered account
  • Authorization
    • Username: email of the registered account
    • Password: password of the registered account

With this configuration, I have 403 error. What I’m doing wrong?
Other question: where can I find post_id and email? Is my process right?

Thank you!
