For developers
REST API
Contacts, companies, deals, tasks, invoices and more: read and write with scoped keys.
Under /api/v1: contacts, companies, deals (with stage moves), tasks, quotes, invoices (issue, payments), products (stock movements), your own records, tickets, purchase orders and shop orders; enrolling in automations, REST hooks and an event feed. Scopes: read, write, quotes:write, invoices:write, forms:submit, analytics:write; 120 requests a minute, and a 429 with Retry-After beyond that. The whole description is public as an OpenAPI document. The raw key is shown once; only its SHA-256 is stored. A key belongs to the organisation rather than a person, so per-user record scope does not apply: narrow an integration with the key's scopes.
