Service 404 Error on DELETE Request to Conversation Service API (/conversation-participants)

Date de publication: Dec 18, 2025
Description

When making a DELETE request to the Conversation Service API endpoint /conversation-participants, a 404 (Not Found) error may occur in Salesforce. This can happen for the following primary reasons:

  • Conversational Service API is disabled: If the API is not enabled at the organization level, the endpoint will not be found, resulting in a 404 error.
  • Incorrect endpoint URL: If the request path or version is incorrect, the resource will not be located, and a 404 error will be returned.
  • Invalid Access Token (JWT — JSON Web Token): If there is an issue with the authentication credentials, the API may deny access
