SSG Entre (GraphQL)
SSG Solutions·AE_HSc_SSGEntreRestConnectorGuide
Overview
The SSG Entre connector integrates AlertEnterprise Guardian with SSG Entre — SSG Solutions' cloud-native access control + visitor management platform. SSG is a smaller specialty PACS vendor with strong adoption in flexible-workspace, corporate-tenant, and shared-building scenarios.
The connector is unusual: despite the "Rest" naming on the AE side, SSG Entre's underlying API is GraphQL. The AE-side connector adapts AE's REST connector framework to consume SSG's GraphQL APIs. This is worth flagging to operators expecting standard REST endpoint URLs — the request bodies are GraphQL queries / mutations, not REST resources.
Architecture: AE → ACF (REST Connector Framework) → SSG Entre Rest Connector → SSG Entre GraphQL APIs → SSG Entre System. OAuth 2.0 client credentials grant; example API host https://api.ssgsolutions.com.
Architecture
Composed from this connector's actors + edges. Trust zones are color-coded; trust crossings render as thicker lines.
Authentication
1 method supported
The SSG Entre GraphQL API authenticates callers via OAuth 2.0 client credentials grant. The connector exchanges its client_id + client_secret for an access token at the SSG token endpoint and includes the token on subsequent GraphQL calls.
Prerequisites
Everything that must be in place for this connector to work, with the owner who's responsible.
SSG Entre 8.4+ with GraphQL API access
customerAn operational SSG Entre deployment (8.4+) with GraphQL API access. The connector targets https://api.ssgsolutions.com (or the customer's tenant URL).
OAuth 2.0 client credentials
customerSSG admin must provision OAuth client credentials (client_id + client_secret) and provide the Token URL.
Known limitations
Documented constraints to set customer expectations before deployment.
"Rest" in the name; GraphQL on the wire
informationalDespite the connector package name ending in "Rest", the underlying SSG Entre API is GraphQL. Operators debugging the connector should expect GraphQL query and mutation request bodies, not REST resource endpoints. This naming reflects AE's REST connector framework hosting the connector rather than the wire protocol used downstream.
PACS specifics
