Morning @mohammedabdelgwad

Thanks for reaching out, Welcome to our community.

Please note that sandbox has it’s own static certificate and it’s only to clarify the onboarding steps, the error you are receiving is to mismatch between the certificate you signed the XML with and the one in the web based validator, However, our recommendation is to start the onboarding process in the Simulation environment using the attached APIs_sim.png URLs for simulation environment.

Additionally, please refer to Educational library and ensure to review all the documentations that will help you during the onboarding process.

If you faced any blocker during the onboarding process, please do not hesitate to reach out your RM to reaching out our support team via below mail:
