openapi: 3.0.3 info: title: Classy API (GoFundMe Pro) Authentication Designations API description: 'The Classy API is a resource-oriented REST API for the Classy online fundraising platform (rebranding to GoFundMe Pro). It exposes Organizations, Campaigns, Fundraising Pages, Fundraising Teams, Transactions, Recurring Donation Plans, Members, Supporters, and Designations, among other resources, under a versioned base path (https://api.classy.org/2.0). Authentication uses OAuth2 client credentials: POST client_id/client_secret/grant_type as a JSON body to /oauth2/auth to receive a Bearer access_token. List endpoints return a Laravel-style pagination envelope (current_page, data, per_page, total, next_page_url, etc.) and support a `with` query parameter to eager-load related sub-resources (for example ?with=items or ?with=source_tracking_codes). This document models the endpoints confirmed against the official classy-org/classy-node resource map and the official classy-org/postman-collections examples; the full resource surface is broader (52+ resource types) and is documented in full only behind Classy/GoFundMe Pro developer credentials. Endpoint coverage: endpointsConfirmed - a curated set of the most-used endpoints across Organizations, Campaigns, Fundraising Pages, Fundraising Teams, Transactions, Recurring Donation Plans, Members, Supporters, and Designations, grounded in classy-org/classy-node''s src/resources.json and classy-org/postman-collections examples. endpointsModeled - request/response shapes for those endpoints, inferred from the Postman collection example bodies (field names, types, and the pagination envelope) since Classy does not publish a machine-readable OpenAPI/Swagger document.' version: '2.0' contact: name: Classy (GoFundMe Pro) url: https://www.classy.org servers: - url: https://api.classy.org/2.0 description: Classy / GoFundMe Pro production API security: - bearerAuth: [] tags: - name: Designations description: Funds or programs donors can direct gifts toward. paths: /designations/{id}: parameters: - $ref: '#/components/parameters/Id' get: operationId: getDesignation tags: - Designations summary: Retrieve a designation responses: '200': description: The requested designation. content: application/json: schema: $ref: '#/components/schemas/Designation' '401': $ref: '#/components/responses/Unauthorized' '404': $ref: '#/components/responses/NotFound' put: operationId: updateDesignation tags: - Designations summary: Update a designation requestBody: required: true content: application/json: schema: $ref: '#/components/schemas/DesignationInput' responses: '200': description: The updated designation. content: application/json: schema: $ref: '#/components/schemas/Designation' '401': $ref: '#/components/responses/Unauthorized' '404': $ref: '#/components/responses/NotFound' '422': $ref: '#/components/responses/ValidationError' components: parameters: Id: name: id in: path required: true description: The numeric ID of the resource. schema: type: integer schemas: Error: type: object properties: error: type: string error_description: type: string permissions: type: array items: type: object properties: action: type: string entity: type: string DesignationInput: type: object required: - name properties: name: type: string description: type: string active: type: boolean additionalProperties: true Designation: allOf: - $ref: '#/components/schemas/DesignationInput' - type: object properties: id: type: integer organization_id: type: integer campaign_id: type: integer nullable: true raw_current_amount: type: number created_at: type: string format: date-time updated_at: type: string format: date-time responses: ValidationError: description: The request payload failed validation. content: application/json: schema: $ref: '#/components/schemas/Error' Unauthorized: description: Missing, invalid, or expired Bearer token. content: application/json: schema: $ref: '#/components/schemas/Error' NotFound: description: The requested resource was not found. content: application/json: schema: $ref: '#/components/schemas/Error' securitySchemes: bearerAuth: type: http scheme: bearer description: 'OAuth2 client_credentials access token obtained from POST /oauth2/auth.
