FAQ
What is the difference between affiliate and API?
With affiliate we sell to the end customer; you earn a commission (20% standard, up to 30%). With the API you sell; we deliver the certificate to you and you set the end price.
How high is the affiliate commission?
Standard is 20% of the list price of the referred certificate. With higher monthly volume, 25% or up to 30% is possible — details in the partner agreement.
Why can the API earn more than affiliate?
Because you set the end-customer price and keep everything above your cost. Even without a prepaid package this can beat affiliate commission when you sell above our list price.
Does the API cost anything?
API usage is free for partners. Issued certificates are billed. We align onboarding and sandbox in a call; the test environment is free to use.
