Either the client request is malformed or some specific processing error
happened that may be the fault of the client as detailed in the JSON body
of the response.
+ This includes the case where the payment is insufficient (sum is below
+ the required total amount, for example because the wallet calculated the
+ fees wrong).
:http:statuscode:`402 Payment required`:
There used to be a sufficient payment, but due to refunds the amount effectively
paid is no longer sufficient. (If the amount is generally insufficient, we
- return "406 Not Acceptable", only if this is because of refunds we return 402.)
+ return "400 Bad Request", only if this is because of refunds we return 402.)
:http:statuscode:`403 Forbidden`:
One of the coin signatures was not valid.
:http:statuscode:`404 Not found`:
The merchant backend could not find the order or the instance and thus cannot process the payment.
- :http:statuscode:`406 Not acceptable`:
- The payment is insufficient (sum is below the required total amount).
- TODO: Should probably change to a different status code in the future as 406 is technically wrong.
:http:statuscode:`408 Request timeout`:
The backend took too long to process the request. Likely the merchant's connection
to the exchange timed out. Try again.
