Syniverse SDC Application Access Token Management API
Regenerates the access token associated with an SDC application via GET /saop-rest-data/v1/apptoken-refresh. This is the token-lifecycle piece of the Syniverse Developer Community bearer-token auth model. Confirmed live on 2026-07-25: both /saop-rest-data/v1/apptoken-refresh and the shorter /apptoken-refresh used by Syniverse's own example code answer on https://api.syniverse.com with {"errorCode":1,"moreInfo":"consumerkey parameter required","userMsg":"consumerkey"}.
