openapi: 3.0.3 info: title: Service Fusion Open Calendar Tasks Techs and Users API description: 'The Service Fusion Open API is a REST/JSON interface to Service Fusion field service management (FSM) software for home-service contractors. It exposes the core operational records - customers and their contacts, jobs (work orders), estimates, invoices, payments, the product/service catalog, technicians, and calendar tasks - over HTTPS. Requests are authenticated with OAuth 2.0; obtain an access token from the token endpoint at https://api.servicefusion.com/oauth/access_token using an authorization_code or client_credentials grant, then send it as a Bearer token. API access is available on the Service Fusion Pro plan and is rate limited to roughly 60 requests per minute. Grounding note - customers, jobs, estimates, invoices, and techs are documented resources on the Service Fusion API. Contacts, products, services, payments, and calendar tasks are modeled here from the Service Fusion FSM data model and the platform''s read-and-create API conventions; verify exact paths, fields, and available methods against the live reference at https://docs.servicefusion.com/ before production use. In practice the public API is read-and-create heavy - list (GET), retrieve (GET), and create (POST) are the reliably available operations; update (PUT) and delete (DELETE) are not consistently exposed across resources.' version: '1.0' contact: name: Service Fusion url: https://www.servicefusion.com servers: - url: https://api.servicefusion.com/v1 description: Service Fusion Open API v1 security: - oauth2: [] - bearerAuth: [] tags: - name: Techs and Users description: Technicians and users the work is assigned to. paths: /techs: get: operationId: listTechs tags: - Techs and Users summary: List techs and users description: Lists the technicians and users in the account. parameters: - $ref: '#/components/parameters/Filters' - $ref: '#/components/parameters/Sort' - $ref: '#/components/parameters/Page' - $ref: '#/components/parameters/PerPage' responses: '200': description: A paginated list of techs and users. content: application/json: schema: $ref: '#/components/schemas/TechList' '401': $ref: '#/components/responses/Unauthorized' /techs/{id}: parameters: - $ref: '#/components/parameters/Id' get: operationId: getTech tags: - Techs and Users summary: Retrieve a tech description: Retrieves a single technician or user by ID. responses: '200': description: The requested tech or user. content: application/json: schema: $ref: '#/components/schemas/Tech' '401': $ref: '#/components/responses/Unauthorized' '404': $ref: '#/components/responses/NotFound' components: parameters: Page: name: page in: query required: false description: 1-based page number for pagination. schema: type: integer minimum: 1 default: 1 Id: name: id in: path required: true description: The unique identifier of the resource. schema: type: string PerPage: name: per-page in: query required: false description: Number of records per page. schema: type: integer minimum: 1 maximum: 100 default: 25 Sort: name: sort in: query required: false description: Sort field, optionally prefixed with - for descending order (for example sort=-start_date).
