# Generate PDF Certificate
Online learning platforms and corporate training departments use this recipe to generate a completion certificate on demand. Define the recipient name, course title, completion date, and a QR code linking to a verification page — producing a landscape PDF ready for formal download or print.
## APIs Used
Document Generation (1 credits/request)
## Prerequisites
