Authentication

To ensure the security of your interaction with the VIA payment system API, you must use the following authentication parameters:

  • client-id: A unique partner identifier provided by the service. The client-id must be sent in the header of each request.
  • client-secret: Authentication key provided by the service. The client-secret key must be sent in the header of each request to confirm your authorization and ensure data security.

Please note that both parameters must be passed in the header of each request. Please ensure that you have correctly configured your application or service to send these parameters in the header.

If you have problems with authentication or retrieving the client-id and client-secret parameters, please contact VIA Payment System Support and we will assist you in resolving any authentication problems.
