my sandbox app has sandbox-ProductInformation V4 enabled and Key Status Approved.
Token requests (client_credentials) succeed, but all calls to /products/v4/search/… on sandbox-api.digikey.com return 403 “The supplied client credentials are not authorized to perform this request”. I recreated the app once and the behavior is identical.
Could you check the authorization on your side ?
