Most API requests are completed successfully, but sometimes things go wrong and an error message is returned instead of the expected response.
Our API provides a variety of descriptive error messages intended to provide the reason for the error and provide suggestions for the appropriate solution.
API error messages can be divided into several different groups (depending upon the type of error, the underlying cause, and the optimal solution), but the format of the API error messages is consistent, and is as follows:
"Severity Level""Error Category":"Error Message"
The "Severity Level" can be either E for an error or W for a warning. The "Error Category" can be one of General, API, Query, Order, Trade, Funding or Service. The "Error Message" can be any text string that describes the reason for the error (such as Invalid arguments).
For example, an error indicating that an invalid currency pair had been used in a ticker query would be as follows:
EQuery:Unknown asset pair
Note that some third party software (mobile apps, trading bots, etc.) choose to hide the original API error and present a customized error instead, hence an alternative error format or content is possible depending upon the software being used.
