REST API

Read and write contacts, read every other list, with scoped keys.

Built inPart of the product. There is nothing to install, only to configure.

Under /api/v1: create, read, update and archive contacts; read companies, deals, tasks, quotes, invoices, products and your own records. Each key carries read or write scope, 120 requests a minute, and a 429 with Retry-After beyond that. 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.
