Error Handling

 

Error Handling

Our APIs use a standardized approach to error handling.

When an error is thrown, the API provider typically expresses the error in two parts:  

  • HTTP Status Code and Reason

  • Error Payload

In general, a 4xx code indicates a client error while a 5xx code indicates a server error. The payload provides more insight into the cause of the error and solution.

HTTP Error Codes

The following section lists the most common HTTP Error Codes and their meanings:

Authorization

Authorization Overview Guide

SEI uses OAuth 2.0, the authorization and authentication mechanism preferred in the industry. OAuth 2.0 ensures security by granting deliberate and verified permissions through API Keys. This document provides a general overview of the process using the authorization code grant type and the API calls used to interact with our service.
