Errors

WalletKit uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, invalid address, etc.). Codes in the 5xx range indicate an error with Stripe’s servers (these are rare).

Some 4xx errors that could be handled programmatically (e.g., transfer amount exceeds balance) include an error code that briefly explains the error reported.

Error Response Format

Besides HTTP status code, error response include supplementary JSON fields that provide a more detailed, programmatic description of errors for enhanced error handling.

• code: For some errors that could be handled programmatically, a short string indicating the error code reported.
• error: A human-readable message providing more details about the error.
