  title: Nooks Sequencing Sequence States API
  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"
