List of common errors and their fixes

While doing some tests or even while the site is live, errors seldom occur. This guide could be handy to find the fix for it, we listed the common errors and their fixes in here:

Invalid or missing parameter 200.300.404
– This error often occurs while the system fetches the payment’s status that has an invalid or a missing parameter.

Error Code
{"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 https://test.oppwa.com/v1/checkouts/xxx5E5B054.sbg-vm-tx02/payment
• 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).
