Best CRM & RevOps APIs
Your CRM is the system of record. For AI-native sales stacks, the CRM that wins is the one with a clean API, webhooks, and an MCP server so agents can read and write records natively.
Prioritize CRMs with comprehensive REST APIs, native webhooks for real-time updates, and SDKs in your language. MCP-ready CRMs let your agent search contacts, log activities, and update pipelines conversationally. Capability coverage — from pipeline analysis to meeting transcript capture — determines how much of your workflow you can hand to an agent.
