Error Handling

Error Handling Process

This section includes the process of error handling to assist developers in taking appropriate actions when encountering errors. It explains how to parse error responses, handle different types of errors, and provide appropriate user feedback, etc.

HTTP Error Handling Process

  1. Please check if the HTTP response status code is 200. If the status code is not 200, it indicates that the responses may be originating from CoinEx's server gateway service, which was previously functioning. In this case, it's not appropriate to parse the response according to the JSON format outlined in our documentation. Instead, it is recommended to directly capture and record the returned response body.
  2. Parse the response body according to the specified error response format (see the next section Error Response Format) to determine whether an error has occurred. If the request is successful, the corresponding error code will return the number '0'. If it's not '0', proceed with the next step.
  3. Refer to the error code table below to determine how to handle the error.
  4. If there is no handling method for this error code in the documentation, please save the request parameters and error response, and contact us for help.

WS Error Handling Process

  1. Parse the response body according to the specified error response format (see the next section Error Response Format) to determine whether an error has occurred. If the request is successful, the corresponding error code will return the number '0'. If it's not '0', proceed with the next step.
  2. Refer to the error code table below to determine how to handle the error.
  3. If there is no handling method for this error code in the documentation, please save the request parameters and error response, and contact us for help.

Error Response Format

When the request fails, the server will return an error response following a specific format. This error response includes an error code and an error message.

The agreed error response formats are as follows:

HTTP Error Response

{
"code": 3008,
"data": {},
"message": "service too busy"
}

WS Error Response

{
"id": 4,
"message": "invalid parameters",
"code": 20001
}
