WebhookCallbackRequest

The webhook callback payload that will be sent to the client's webhook endpoint when a classification is completed. Only clients who have specifically opted to receive webhook callbacks need to implement this endpoint. This is an optional feature for "Item Classification Without Storage" customers.

Authentication: The webhook callback supports two authentication methods:

  • Basic Authentication: Requires an API key configured in the Avalara system
  • OAuth: Requires an OAuth token endpoint to be configured in the Avalara system

Conditional Fields:

  • The hsCode field is included for HS classification activities such as hs6, hsFull, and export HS flows
  • The eccnCode and countryOfExport fields are included for ECCN classification activities when available
  • The countryOfOrigin field is included for COO classification activities when available
  • The possibleHsCodes field is only included when the broker parameter is set to "true" and there are alternative HS codes available

Retry Behavior: If the webhook call fails due to server connectivity issues, the system will automatically retry the call.

This model is used in the following APIs:
