Get a webhook by ID
AI agents call getWebhook to retrieve information from Follow Up Boss MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves webhook configuration data by ID. It performs a read-only operation that does not create, modify, delete, or execute any actions. The blast radius is minimal as it only returns existing webhook information.
From the tool's definition Tool name 'getWebhook' and description 'Get a webhook by ID' both indicate a retrieval operation with no modification or side effects.
