If you want your users to earn a certificate at a certain point in the pathway, you can create certificates and then assign them to a Certificate Activity. Note: You will not be able to insert this activity into your pathway if there are no existing certificates to assign.
Select one of your existing / available certificates.
Add text and links.
Certificate activities are pre-set as "required" and can not be skipped, i.e. all users who reach this activity will earn a certificate.
When the user reaches this activity it will be fulfilled.
