New API: Pricing Plans Backend Functions and Events

Hi I´ve started a new project tha is and online school
i´ll have a bunch of diferent courses = differents plan prices

but i´m having a problem
i need that the member who bought a course ( plan ) see only the course that he has bought.

i´ve tried different codes for it but i´m not having sucess

i´ve got diferrents Database for each course, because it´s linked with dynamic pages with all the course content
And have 1 Data for the member

but i-m having trouble to show for that expecific member only the course or courses that he bought

FOR EXAMPLE
i´ve bought a free course and a 100 U$ course

in my member page nedd to be showed only these 2 courses not all the courses that i-ve got

it´s that possible ?

Thanks a lot
