openapi: 3.1.0 info: title: Customer.io App Activities Snippets API description: The Customer.io App API enables developers to manage workspace resources and send messages programmatically. It provides endpoints for sending transactional messages, triggering broadcasts, managing customers and segments, retrieving campaign and newsletter data, and exporting customer information. The API uses bearer token authentication with an App API key and is designed for operations that go beyond data ingestion, such as retrieving metrics, managing message templates, and automating outbound communications from Customer.io. version: 1.0.0 contact: name: Customer.io Support url: https://customer.io/contact termsOfService: https://customer.io/legal/terms-of-service servers: - url: https://api.customer.io/v1 description: US Production Server - url: https://api-eu.customer.io/v1 description: EU Production Server security: - bearerAuth: [] tags: - name: Snippets description: Manage reusable content snippets for use in messages. paths: /snippets: get: operationId: listSnippets summary: List snippets description: Returns a list of reusable content snippets in your workspace. tags: - Snippets responses: '200': description: A list of snippets. content: application/json: schema: type: object properties: snippets: type: array items: $ref: '#/components/schemas/Snippet' '401': description: Unauthorized.
