openapi: 3.0.1 info: title: Extend Batch Workflows API description: The Extend API turns documents into high quality structured data. It exposes file management, synchronous and asynchronous document processors (parse, extract, classify, split), reusable processor definitions (extractors, classifiers, splitters), durable multi-step workflows and workflow runs, evaluation sets, and batch processing. All requests are authenticated with a Bearer API token and should pin an API version via the x-extend-api-version header. termsOfService: https://www.extend.ai contact: name: Extend Support url: https://docs.extend.ai version: '2026-02-09' servers: - url: https://api.extend.ai description: Extend production API security: - BearerAuth: [] tags: - name: Workflows paths: /workflows: get: operationId: listWorkflows tags: - Workflows summary: List workflows parameters: - $ref: '#/components/parameters/ApiVersion' - $ref: '#/components/parameters/NextPageToken' - $ref: '#/components/parameters/MaxPageSize' responses: '200': description: A page of workflows. content: application/json: schema: type: object properties: workflows: type: array items: $ref: '#/components/schemas/Workflow' nextPageToken: type: string default: $ref: '#/components/responses/ApiError' post: operationId: createWorkflow tags: - Workflows summary: Create a workflow parameters: - $ref: '#/components/parameters/ApiVersion' requestBody: required: true content: application/json: schema: type: object required: - name properties: name: type: string description: type: string responses: '200': description: The created workflow. content: application/json: schema: $ref: '#/components/schemas/Workflow' default: $ref: '#/components/responses/ApiError' /workflows/{id}: get: operationId: getWorkflow tags: - Workflows summary: Get a workflow parameters: - $ref: '#/components/parameters/ApiVersion' - $ref: '#/components/parameters/PathId' responses: '200': description: The requested workflow. content: application/json: schema: $ref: '#/components/schemas/Workflow' default: $ref: '#/components/responses/ApiError' components: schemas: Workflow: type: object properties: object: type: string example: workflow id: type: string name: type: string description: type: string version: type: string createdAt: type: string format: date-time updatedAt: type: string format: date-time ApiError: type: object properties: code: type: string message: type: string retryable: type: boolean requestId: type: string parameters: PathId: name: id in: path required: true schema: type: string MaxPageSize: name: maxPageSize in: query required: false schema: type: integer NextPageToken: name: nextPageToken in: query required: false schema: type: string ApiVersion: name: x-extend-api-version in: header required: false description: API version to pin the request to, for example 2026-02-09. schema: type: string example: '2026-02-09' responses: ApiError: description: Error response. content: application/json: schema: $ref: '#/components/schemas/ApiError' securitySchemes: BearerAuth: type: http scheme: bearer description: Provide your Extend API token as a Bearer token in the Authorization header.
