Call Options

Call parameters are divided into two types:

  • Path parameters (token)
  • Query parameters (transaction data)

The token is generated in the internal account of the merchant at the first stage of adding the web-site.

The request parameters are generated by the merchant and sent to the server using the POST method in the application / x-www-form-urlencoded or application / json format.

Below you can find the example of processing payment information with LOVAT.
