Response Status and Error Codes
When using our API, you may encounter certain status and error codes. Whilst a message is being processed it has a state code and possibly also an error code. The state code indicates what is/has happened to the message. This page contains a list of all Response Status and Error Codes with descriptions
HTTP Status Codes
All HTTP response status codes are separated into five classes or categories. The first digit of the status code defines the class of response, while the last two digits do not have any classifying or categorization role. There are five classes defined by the standard:
1xx informational response – the request was received, continuing process
2xx successful – the request was successfully received, understood, and accepted
3xx redirection – further action needs to be taken in order to complete the request
4xx client error – the request contains bad syntax or cannot be fulfilled
5xx server error – the server failed to fulfil an apparently valid request
