Registration
To gain access to the VIA payment system API and obtain the client-id and client-secret parameters, you will need to contact your VIA system integrator.
The system integrator will be responsible for register your applications or services to the VIA payment system and will provide you with a client-id and client-secret for authentication when using the API.
If you have any questions or problems registering and gaining access to the VIA API, please contact our support team and we will be happy to help you resolve any issues.
