Once the course test has been complete, are you required to upgrade and pay that fee before giving you your certificate?
Hi @Mike_Harris
Welcome to the Open edX® Community! Glad to see you here.
Is your question in reference to a course on edX.org? If so, which course? (can you send a link please?). Yes, usually you need to pay to upgrade to the certificate track for edX.org courses.
This community is for questions related to Open edX®, the open source software that powers thousands of online courses around the world, including edX.org and its courses.
