  version: 0.1.0
  description: "The Nooks Sequencing API provides programmatic access to manage sequences, tasks, templates, and prospect engagement workflows created using the Nooks SEP.\n\n## Authentication\n\nSend a bearer token in the `Authorization` header:\n```\nAuthorization: Bearer <token>\n```\n\nTwo token types are accepted on the same header — the API detects which\nformat you sent and validates accordingly. If you already have a token,\npaste it into the Authentication panel and skip the flow setup.\n\n### API keys\n\nLong-lived, workspace-scoped. Best for backend integrations and\nserver-to-server automation. Generate one from **Developer Settings →\nAPI Keys** in your Nooks workspace. API keys are prefixed `nooks-api-`\nand have full read/write access within the owning workspace.\n\n### OAuth 2.0 access tokens\n\nShort-lived (1 hour), user-scoped, scope-limited JWTs issued by\n`https://oauth.nooks.in` via the standard authorization-code + PKCE flow.\nBest for third-party apps acting on behalf of a specific user — the token\ncarries that user's identity and a subset of scopes the user consented\nto. Refresh tokens rotate every 90 days and are invalidated on first\nre-use (refresh-token reuse detection).\n\n**Endpoints:**\n\n- Authorize: `https://oauth.nooks.in/oauth/authorize`\n- Token: `https://oauth.nooks.in/oauth/token`\n- JWKS: `https://oauth.nooks.in/.well-known/jwks.json`\n- Server metadata (RFC 8414): `https://oauth.nooks.in/.well-known/oauth-authorization-server`\n\n**Available scopes:**\n\n| Scope | Grants |\n| --- | --- |\n| `prospects:read` | View your prospects |\n| `prospects:write` | Create and update prospects |\n| `sequences:read` | View your sequences |\n| `sequences:write` | Create and update sequences |\n| `sequence-steps:read` | View sequence steps |\n| `sequence-states:read` | View sequence enrollments |\n| `sequence-states:write` | Enroll prospects and manage enrollments |\n| `tasks:read` | View your tasks |\n| `tasks:write` | Create, update, complete, skip, and delete tasks |\n| `calls:read` | View your calls |\n| `calls:write` | Create and update calls |\n| `call-dispositions:read` | View call dispositions |\n| `emails:read` | View your emails |\n| `emails:write` | Create and update emails |\n| `mailboxes:read` | View connected mailboxes |\n| `users:read` | View users in your workspace |\n| `accounts:read` | View accounts (companies) in your workspace |\n| `notes:write` | Create notes on CRM-backed prospects and accounts |\n| `opportunities:read` | View opportunities (deals) in your workspace |\n| `search:read` | Search across your prospects, accounts, and other records |\n\n## Rate Limiting\nAPI requests are rate limited per workspace and per endpoint in a fixed\none-minute window. Separate endpoint buckets do not share quota, except\nroutes without an explicit limit use the shared default bucket.\n\nEvery response includes these headers:\n- `X-RateLimit-Limit` -- maximum requests allowed in the current per-minute window\n- `X-RateLimit-Remaining` -- requests remaining in the current window\n- `X-RateLimit-Reset` -- seconds until the current window resets\n\nWhen the limit is exceeded the API returns `429 Too Many Requests` with a\n`Retry-After` header indicating how many seconds to wait before retrying.\n\n**Current limits:**\n\n| Endpoint class | Methods | Limit |\n| --- | --- | --- |\n| List reads: `/sequences`, `/emails`, `/users`, `/sequenceStates`, `/prospects`, `/mailboxes`, `/calls`, `/sequenceSteps`, `/callDispositions`, `/tasks`, `/accounts` | `GET` | 300 requests/minute per endpoint |\n| Read by ID: `/sequences/{id}`, `/emails/{id}`, `/users/{id}`, `/sequenceStates/{id}`, `/prospects/{id}`, `/mailboxes/{id}`, `/calls/{id}`, `/sequenceSteps/{id}`, `/callDispositions/{id}`, `/tasks/{id}`, `/accounts/{id}`, `/emailTemplate/{id}` | `GET` | 600 requests/minute per endpoint |\n| Sequence writes: `/sequences`, `/sequences/{id}` | `POST`, `PATCH` | 120 requests/minute per endpoint |\n| Sequence state writes: `/sequenceStates`, `/sequenceStates/{id}`, `/sequenceStates/{id}/actions/finish` | `POST`, `DELETE` | 120 requests/minute per endpoint |\n| Task writes: `/tasks`, `/tasks/{id}`, `/tasks/{id}/complete`, `/tasks/{id}/skip` | `POST`, `PATCH`, `DELETE` | 120 requests/minute per endpoint |\n| CRM note writes: `/prospects/{id}/notes`, `/accounts/{id}/notes` | `POST` | 30 requests/minute per endpoint |\n| `/integrations/prospects/sync` | `POST` | 10 requests/minute |\n| Any other endpoint | Any | 30 requests/minute, shared default bucket |\n\n## Pagination\nList endpoints support cursor-based pagination using the `page[size]` and `page[after]`/`page[before]` query parameters.\n- Maximum page size: 100\n- Default page size: 50\n\n## Include (Inline Expansion)\nMost GET endpoints support an `include` query parameter that expands related `ReferenceObject` fields inline,\neliminating the need for follow-up API calls.\n\n**Format:** `?include=field1,field2` (comma-separated field names)\n\n**Without include:**\n```json\nGET /v1/prospects/123\n\n{\n  \"id\": \"123\",\n  \"sequenceStates\": [\n    { \"id\": \"ss-1\", \"_href\": \"/v1/sequenceStates/ss-1\" }\n  ]\n}\n```\n\n**With `include=sequenceStates`:**\n```json\nGET /v1/prospects/123?include=sequenceStates\n\n{\n  \"id\": \"123\",\n  \"sequenceStates\": [\n    {\n      \"id\": \"ss-1\",\n      \"_href\": \"/v1/sequenceStates/ss-1\",\n      \"state\": \"active\",\n      \"sequence\": { \"id\": \"seq-1\", \"_href\": \"/v1/sequences/seq-1\" },\n      \"prospect\": { \"id\": \"123\", \"_href\": \"/v1/prospects/123\" },\n      \"creator\": { \"id\": \"u-1\", \"_href\": \"/v1/users/u-1\" },\n      \"sequenceStep\": null,\n      \"createdAt\": \"2024-01-01T00:00:00Z\",\n      \"updatedAt\": \"2024-01-01T00:00:00Z\"\n    }\n  ]\n}\n```\n\nThe expanded object is a superset of `ReferenceObject` — it keeps `id` and `_href` and adds all DTO fields.\nThe response shape is unchanged; the field just contains richer data.\n\n**Hard constraints (enforced with 400 errors):**\n- **Max 3 includes per request.** Requesting more than 3 comma-separated values returns `400: \"include accepts at most 3 values\"`.\n- **GET endpoints only.** POST, PATCH, and DELETE endpoints do not accept `include`.\n- **No nested includes.** Only top-level field names are valid (e.g., `sequenceStates`). Dot-notation like `sequenceStates.prospect` returns 400.\n- **`account` on Prospect is not includable.** Requesting `include=account` returns 400.\n\nEach endpoint's `include` parameter lists the valid field names for that resource.\n"

      description: "Returns a paginated list of calls made on the Nooks SEP. Supports filtering by ID and updatedAt range.\n\nThere is no fixed API-enforced historical lookback window for this\nendpoint. You can page through all retained Nooks SEP call records\navailable in the workspace. Historical availability depends on when\nthe workspace started using Nooks SEP and the workspace's retained call\ndata.
