SMBcrm Developer Center
Build directly on your own SMBcrm account with a REST API, an MCP server for AI agents, and webhooks for real-time events.
Build on your SMBcrm account
Section titled “Build on your SMBcrm account”This portal covers building directly on your own SMBcrm account: automating work, syncing data, and extending what your account can do. Authenticate with an OAuth access token or a Private Integration Token, then use the same REST API and MCP server that SMBcrm runs on. Every endpoint here works against a single account/location: the one your token belongs to.
