Ignition Gateway REST API
The Ignition Gateway REST API (available in Ignition 8.3+) provides an OpenAPI- compliant HTTP interface to Gateway configuration resources including tags, projects, modules, device connections, and historian data. The API spec is dynamically generated and includes all routes exposed by installed modules. Authentication uses API keys with time-limited tokens. Mutative requests are audit-logged. Supports Kubernetes and Helm-based cloud-native deployments.
