Errors & Troubleshooting

The API v1 emits two types of errors: proxied VAN errors, and API Proxy errors. Errors from MIG code follow the proposed problem details standard, with an additional “source” property to help identify the component.

VAN errors follow the scheme outlined in the VAN API error documentation. DDx API performs light validation on request properties to ensure we only send requests that can succeed. If the Proxy is unable to deliver a request to the VAN API you will receive an error message. You can find examples of DDx API error messages below.
