Think of it as a native Zapier integration, helping you showcase your best Zapier-powered workflows where it's most helpful to your users (within the flow of your tool). You can customize styling, streamline Zap set-up for users, expose relevant Zap information, and more! With the Partner API, you can: - Get a list of all the apps available in Zapier's app directory so you can power your app directory and show your users all the integration possibilities with your Zapier integration. - Have complete style control over how you present Zap templates in your product. The Partner API gives you access to the raw Zap Template data so you can give your users access to your Zap template with your product's style, look and feel. - Get access to all your Zap templates and give your users the ability to search to quickly find the one they need. - Streamline Zap setup by pre-filling fields on behalf of your users. - Show users the Zaps they have set up from right within your product keeping them on your site longer and giving them complete confidence in their Zapier integration. - Embed our Zapier Editor to allow your users to create new Zaps and modify existing ones, without needing to leave your product. ## Authentication There are two ways to authenticate with the Partner API. 1. Your application's `client_id` which you will receive once you are approved for access to the API (Client ID Authentication) 2. A user's access token (Access Token Authentication). Which authentication method you should use depends on which endpoint(s) you are using. Review each endpoint's documentation to understand which parameters are required. > Note: while we do generate a `client_secret`, the type of grant we use (implicit) doesn't need it so it's not something we provide.' ## Learn more See the [Workflow API documentation](https://docs.zapier.com/partner-solutions/workflow-api/intro) for more information. contact: name: Zapier url: https://developer.zapier.com/contact servers: - url: https://api.zapier.com security: [] tags: - name: Accounts description: Refers to resources interacting with 'Accounts' associated resources - name: Actions description: Refers to resources interacting with 'Actions' associated resources - name: Apps description: Refers to resources interacting with 'Apps' associated resources - name: Authentications description: >- Refers to resources interacting with 'Authentications' associated resources - name: Categories description: Refers to resources interacting with 'Categories' associated resources - name: Experimental description: Refers to resources interacting with 'Experimental' associated resources - name: Inputs description: Refers to resources interacting with 'Inputs' associated resources - name: Outputs description: Refers to resources interacting with 'Outputs' associated resources - name: Zaps description: Refers to resources interacting with 'Zaps' associated resources - name: Zap Templates description: Refers to resources interacting with 'Zap Templates' associated resources paths: /v2/actions/{action_id}/inputs/{input_id}/choices: post: tags: - Actions - Inputs summary: Get Choices description: |- Get the possible values for a `SELECT` Input Field. #### When using OAuth This endpoint requires the `zap` OAuth scope. operationId: get-choices parameters: - in: path name: action_id schema: type: string description: An Action ID, as provided by the `/actions` endpoint. required: true example: uag:87b1c14e-ef30-43d5-9395-6c6514dbb123 - in: path name: input_id schema: type: string description: An Input Field ID, as provided by the `/inputs` endpoint. required: true example: lead_id - in: query name: page schema: type: string default: '1' description: The page of choices to return, defaults to the first example: '1' requestBody: content: application/json: schema: $ref: '#/components/schemas/ChoiceRequest' required: true responses: '200': content: application/json: schema: type: array items: $ref: '#/components/schemas/ChoiceResponse' examples: ChoicesForSomeAction: value: - data: - id: 55c type: choice label: First value: example - id: a73 type: choice label: Second value: example links: next: null prev: null meta: page: 1 summary: Choices for Some Action description: '' '400': content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' examples: MalformedRequest.: value: errors: - status: 400 code: parse_error title: ParseError detail: Malformed request. source: null meta: source: ZAPIER full_details: message: Malformed request. code: parse_error summary: Malformed request. description: This schema can be expected for 4xx 'Malformed request.' errors '401': content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' description: 401 Response '403': content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' description: 403 Response '409': content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' description: 409 Response '429': headers: Retry-After: schema: type: string format: uri description: Indicates when to retry the request X-RateLimit-Limit: schema: type: string format: uri description: >- The maximum number of requests you're permitted to make per hour.
