Response Codes

The LoanPro API provides standard HTTP response codes, and most requests will result in codes within the 2xx range and the 4xx range. Here is a summary of the response codes provided by our API:

Response Code	Description	Common Reason
`200 OK`	Nice! Your request was successful.	You're great at reading documentation and an all-around awesome individual.
`401 Authentication Error`	An authentication error occurred.	A `401` response typically means there's an error with your headers. We couldn't validate your API key, tenant ID, or both.
`404 Not Found`	The information in the request could not be found.	This response is rare. Our API will typically give you a `409` response instead if a resource is missing. However, you may receive this response if an invalid endpoint is used.
`409 Conflict`	A conflict occurred which resulted in a failure.	A `409` response typically means there's an error with the request's payload, endpoint, or both. Here are a few common failure causes: - Missing required payload fields - Typos within the endpoint - Missing or invalid entity IDs such as customer IDs and loan IDs - Sending mismatching payload and endpoint information—like sending customer information to the `Loans` endpoint.
`500 Internal Server Error`	There was an error on our end.	This response is also rare. Typically, it means we had an issue handling your request due to an error with one of our services. You will also receive this error code if your request results in a timeout.
