openapi: 3.0.3 info: title: Attio REST Attributes Webhooks API description: 'The Attio REST API exposes the Attio CRM''s object/attribute/record data model over HTTPS. Attio is an AI-native CRM built on flexible objects (people, companies, deals, users, workspaces, and custom objects), typed attributes, records, and lists. This specification covers the core data-model, activity, collaboration, and platform endpoints: objects, records, attributes, lists, list entries, notes, tasks, comments, threads, webhooks, workspace members, and token identification. All requests are authenticated with a Bearer access token (API key or OAuth) and scoped by granular permissions. Endpoints marked modeled in the repository review were derived from Attio''s published endpoint reference and follow Attio''s documented /v2 path conventions.' version: '2.0' contact: name: Attio url: https://attio.com license: name: Proprietary url: https://attio.com/legal servers: - url: https://api.attio.com/v2 description: Attio REST API v2 security: - bearerAuth: [] tags: - name: Webhooks description: Webhook subscriptions delivering signed HTTP callbacks on changes. paths: /webhooks: get: operationId: listWebhooks tags: - Webhooks summary: List webhooks description: Gets all of the webhooks in your workspace. responses: '200': description: A list of webhooks. post: operationId: createWebhook tags: - Webhooks summary: Create a webhook description: Creates a webhook and its associated event subscriptions. requestBody: required: true content: application/json: schema: type: object responses: '200': description: The created webhook. /webhooks/{webhook_id}: parameters: - name: webhook_id in: path required: true schema: type: string get: operationId: getWebhook tags: - Webhooks summary: Get a webhook description: Gets a single webhook by its webhook_id. responses: '200': description: The requested webhook. patch: operationId: updateWebhook tags: - Webhooks summary: Update a webhook description: Updates a webhook and its associated subscriptions. requestBody: required: true content: application/json: schema: type: object responses: '200': description: The updated webhook. delete: operationId: deleteWebhook tags: - Webhooks summary: Delete a webhook description: Deletes a webhook by its webhook_id. responses: '200': description: The webhook was deleted. components: securitySchemes: bearerAuth: type: http scheme: bearer description: Attio access token (API key or OAuth 2.0 bearer token) with the required scopes.
