API Error Codes

Funnel Leasing uses conventional HTTP response codes to indicate the success or failure of an API request. Here is a general overview:

• Codes in the 2xx range indicate success.
• Codes in the 4xx range indicate an error due to the provided information.
• Codes in the 5xx range indicate a server error on Funnel Leasing’s end.

Some 4xx errors include an error code that explains the issue with a human-friendly message.

Attributes

• code: integer - Represents the specific error code returned by the API.
• message: nullable string - A human-readable message describing the error.
• param: nullable string - The parameter that caused the error (if applicable).
