What causes a 404 error on the v4 indexing endpoint (Search and Match API), and how can it be resolved?

A 404 error on the v4 indexing endpoint typically indicates that the request is targeting an incorrect endpoint or path—for example, using a v4 path that does not exist for the specific operation, or it is case sensitive.

Recommended Steps:

1. Verify that the exact URL being called matches the integration documentation for the operation.
2. If further assistance is required, send a sanitized request and endpoint to RChilli Support for review.
