Nimble REST API is one of 13 APIs that [Nimble](https://apis.io/providers/nimble/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include CRM, Contacts, Deals, Activities, and Task. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, authentication docs, a getting-started guide, and a support channel.

The Nimble CRM REST API — 89 operations across contacts, contact custom fields, contact and deal pipelines, deals, leads, activities, tasks, messages and users. Nimble publishes a full OpenAPI 3.0.0 contract (58 paths, 180 component schemas) embedded in its developer reference. Authentication accepts an account API key as an X-Nimble-Token header or an Authorization: Bearer token, or OAuth 2.0 authorization_code with the coarse basic / contacts / deals scopes. Versioning is per resource family: /api/v1 for contacts, /api/v2 for deals.
