Supply applicationSlug to disambiguate when the same trigger slug exists under more than one application. A trigger type that exists but whose connector cannot currently be subscribed to answers 404 with a message distinguishing it from an unknown slug. ## OpenAPI ````yaml /developers/api-reference/openapi.json get /v1/triggers/types/{triggerSlug} openapi: 3.0.0 info: title: Engini API version: v1 description: The Engini public API. servers: - url: https://api.engini.io security: - Bearer: [] - ApiKey: [] tags: - name: Auth description: Identify the caller a Developer API request is authenticated as. - name: On-prem agents description: >- Provision and manage agents that run Engini tasks inside a customer's network. - name: Applications description: >- Discover the applications (toolkits) available in Engini and their connection requirements. - name: Tools description: Browse and execute the tools exposed by Engini applications. - name: Toolsets description: Manage toolsets - named groupings of connections and tools. - name: McpServers description: >- Inspect and maintain MCP servers - the account-wide endpoints that expose Engini tools and workflows over the Model Context Protocol.
