Common errors with the Copy and Pay integration


This page describes the most common errors that can come up when doing a Copy and Pay integration.

Invalid or missing parameter 200.300.404

You try to GET the payment status in step 3, but you get an error message invalid or missing parameter.

{"result":{"code":"200.300.404","description":"invalid or missing parameter - (opp) No payment session found for the requested id - are you mixing test/live servers or have you paid more than 30min ago?"},"buildNumber":"82d393aad4390f43d567cfe15346f9e89bda7fae@2018-05-25 08:09:59 +0000","timestamp":"2018-05-28 07:36:55+0000","ndc":"5a17f05d53944ae1b2fe3d22f03e0881"}

Possible fixes

  • You are mixing up live end test endpoints
  • You have waited more than 30 minutes with step 3 and therefore the checkout id has expired
  • You are requesting the status with the checkout ID AND the parameters (username, password, entityId). If this is the case, remove the parameters form the request and use the checkout id only. For example
  • You are requesting the payment status for the second time. You can only request the status once with the checkoutID (after one time the checkoutID expires). To request the payment status a second time, please see this page
