(VB.NET) CardConnect Validate Merchant-Level CredentialsTo test and validate merchant-level credentials, you can make a PUT request, including the merchant ID in the body of the request, to the base URL. The Gateway verifies that the MID matches the credentials provided in the header.
' This example assumes the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim http As New Chilkat.Http http.BasicAuth = True http.Login = "API_USERNAME" http.Password = "API_PASSWORD" Dim json As New Chilkat.JsonObject Dim success As Boolean = json.UpdateString("merchid","MERCHANT_ID") Dim url As String = "https://<site>.cardconnect.com:<port>/cardconnect/rest/" Dim responseStr As String = http.PutText(url,json.Emit(),"utf-8","application/json",False,False) If (http.LastMethodSuccess = False) Then Debug.WriteLine(http.LastErrorText) Exit Sub End If ' If we get a 200 response status and an HTML response saying "CardConnect REST Servlet", then our credentials are correct. Debug.WriteLine("response status code = " & http.LastStatus) Debug.WriteLine("response string:") Debug.WriteLine(responseStr) ' Sample output: ' response status code = 200 ' response string: ' <html lang="en"><body><h1>CardConnect REST Servlet</h1></body></html |
