Error Responses

HTTP Status Codes

API responses will yield to appropriate status codes in most circumstances (see Order Related Errors below). In this case, if you receive a 400 response, you can check the body of the response and find an error message that will help decipher the error.

In the event of a 401 response, this is related to authentication and entitlement. Make sure that you’re using the correct credentials and endpoint for your access.

500 errors typically mean that something isn't working properly with the API. Please let us know by emailing techsupport@tradier.com.

Presently, the API sends back a 200 response for any error that is thrown by downstream systems (risk management systems, market centers, etc). This 200 response body will include an errors property with details about the error. This is most likely to occur on complex order placement, order modification, and order cancellation.

In the event you receive this errors payload, it will typically include a description of the problem. In the event you receive an error code, here is a mapping table for errors you can expect:
