API collections

SUMMARY

• API collections in Workato are groups of endpoints with a common access pattern.
• Collections contain either API recipe endpoints, which are endpoints built from API recipes ("build your own backend"), API proxy endpoints, which forward requests to an API backend ("bring your own backend"), or AI gateway endpoints, which are endpoints exposed to LLMs and GPTs, enabling AI applications to take actions on your behalf.
• Workato offers machine-readable documentation (OpenAPI v3.0) for endpoints in an API collection. The documentation can then be synced to Postman.

An API collection consists of API endpoints with a common access pattern, so that they can be managed together. For example, a set of Salesforce endpoints that will be called by recipes used by the Sales team should be grouped together into an API collection.

The API collections page displays all API collections within a workspace. Go to Platform > API platform > API collections to access the API collections page.

A collection can include either API proxy endpoints, API recipe endpoints, or AI gateway endpoints. Collections containing API proxy endpoints have an API proxy label.

Collection types

There are three types of API collections:

• API proxy collection
• API recipe collection
• AI gateway collection

Choose a collection type

The type of collection you choose to create depends on your use case.

• Choose an API proxy collection when you want to bring your own backend. When a proxy endpoint receives an incoming request, Workato simply forwards the request to your existing API backend.

  API proxy collections are ideal in this scenario for the following reasons:

  • API proxy collections are optimized for high-volume, low-cost jobs.
  • Proxy jobs are executed with minimal latency.
  • Proxy requests are not subject to concurrency limits.
  • With API proxy collections, customization options are limited since the main function is to forward requests.

• Choose an API recipe collection when you plan to build your own backend. To do this, you must create an API recipe containing the required logic to fetch and/or process data from other sources (such as external APIs). For example, your recipe could use the Salesforce API to search for opportunities that match a particular name, and if the search returns no matches, it could then create the opportunity according to a specific configuration.

  API recipe collections are ideal in this scenario for the following reasons:

  • API recipe collections are optimized for high-value jobs.
  • API recipes jobs are subject to a concurrency limit.
  • API recipe collections provide the flexibility to highly customize how you fetch and process data.

• Choose an AI gateway collection if you plan to expose endpoints to LLMs, GPTs, or other AI applications. This exposure enables AI applications to take actions on your behalf.

AI gateway collections are ideal in this scenario for the following reasons:

• AI gateway collections allow you to specify an authorization mechanism between Workato and the AI agent to keep your requests secure.
• AI gateway collections allow you to upload you OpenAPI Specification (OAS) from Workato to prevent additional processing for your AI agents.

The right balance of recipe-based, proxy-based, and AI-based collections can help you optimize your API platform (opens new window) usage.

API proxy collections

An API proxy collection is a collection of proxy endpoints. Each endpoint acts as an intermediary between an API client and API server. When you send a request to a proxy endpoint, Workato forwards that request to an endpoint within the backend API.

You can use proxy endpoints to add a layer of security and control to an internal API. Your teammates and external collaborators send requests to the secure proxy endpoint instead of directly to your backend API. This also allows you to benefit from the API Platform's monitoring and access control features.

COLLECTION TYPES

If you're uncertain whether an API recipe collection, API proxy collection, or an AI gateway collection best fits your use case refer to our guide on Choosing a collection type for more information.

Prerequisites for API proxy collections

• Create a project or select an existing project.
• Create an HTTP connection to forward requests to in the project in you plan to use.

SUPPORTED AUTHENTICATION TYPES

API proxy collections support the following HTTP connection authentication types:

• No auth
• Query
• Basic
• Header
• OAuth 2.0 (Client credentials grant)

If you choose a connection with an unsupported authentication type, Workato displays an Unsupported authentication type error message.

6

Use Choose a configuration type to specify the configuration you plan to use in your proxy collection:

• Import OpenAPI Specification

• Upload a JSON or UTF-8 encoded YAML OpenAPI 3.0 (opens new window) specification file, or enter the URL of the specification. Workato uses the OpenAPI specification to automatically set up the schema for the endpoints you add in the next step. Note that we currently do not support time values. For example, 2024-07-18T10:00:00Z must be changed to "2024-07-18T10:00:00Z".

• Manual configuration

• Workato creates an empty collection to which you can add endpoints later. For details, see Configure the schema.

7

Only if you imported an OpenAPI specification: Go to Customize endpoints and select the checkbox next to each endpoint you plan to add to the collection. You can select Edit details next to an endpoint to configure the following information:

• Endpoint name

• Enter a descriptive name for the proxy endpoint.

• Endpoint path

• Define an endpoint path to be appended to both proxy and target base URLs. It can include path parameters. Ensure that the endpoint path conforms to these guidelines.

• HTTP method

• Select the HTTP method to use for the endpoint.

• Request timeout

• Only required when you toggle Customize timeout. Customize the time that a request is given to complete. The default value is 30 seconds and the maximum value is 240 seconds.

Enable specific users or apps to access this collection by assigning this collection to a client's access profile. Learn how to create a new access profile.

API recipe collection

An API recipe collection is a set of endpoints that are each built from an individual API recipe. One recipe corresponds to one endpoint.

With a collection of API recipes, you can make powerful API endpoints available to internal users (such as other team members) and external users (such as your organization's end users, even if they don't have a Workato account). You can also configure other recipes in your workspace to use API recipe collections.

By grouping related API recipe endpoints into a collection, you can easily manage access to the endpoints.

Machine-readable documentation (OpenAPI)

Video guide: How to build APIs faster with OpenAPI

The API collection page has a link in the upper-right corner labeled Download OpenAPI spec. The link gives you access to a downloadable file that contains documentation for all the endpoints within the collection, in a format that can be used by tools such as Postman. This format is called OpenAPI, also known as Swagger.

Workato supports exporting specifications in OpenAPI version 3.0 (opens new window) by default. However, to ensure backward compatibility, Workato also supports exporting specifications in OpenAPI version 2.0 (opens new window). To export a specification in version 2.0, add the query parameter oas_ver=2 to the download URL. For example:

https://app.workato.com/doc/service/collection-name/swagger?api_group_id=123456&token=token-value&oas_ver=2
