HTTP response codes
If our API is able to process your requests properly the response status code is always 200 OK. But in case if there are any kind of technical issue, a failure or maintanence, your request can receive an error response or for a malformed request you can receive a client error response. We recommend you to check the status code for every response and if it is not 200 OK then wait few seconds and repeat the request. You can also log your request data and the response for debugging purposes, this info can be useful when contacting our support team.
