Problem Statement :
Course Creator should be able to attach more than one certificate template to a course so that users receive different certificates based on the defined filter criteria for each template. The creator should also be able to delete one or more certificate templates from the course.
Solution Approach :
1. Add Certificate Template
API Specification : API should take the course details , certificate name and the metadata of the certificate template which has to be attached for that particular course. Course creator can add new certificate template to the course by specifying the filter criteria for issuing the certificate, in the filters field of the API as well as add weight to each certificate template.Weight field will ensure that only one certificate is issued to a particular user. The filters and weight field will be added as a new entry in the metadata of the certificate.
2. Delete Certificate Template
API Specification : API should take the course details and name of the certificate which the course creator wants to delete.
API Design :
Add Certificate Template API
