Workflow Automation

Calling any API

In this guide, you will learn how to set up an HTTP Fetch action to call any API in Lindy.

Lindy supports 3,000+ integrations out of the box, but if you have custom APIs you want to call, you can use the HTTP Fetch action.

Setup

To get started, click the plus sign beside Lindies to start building your Lindy.

Click "Start from scratch" to create a new Lindy.

Add a Trigger

Click “select trigger”, then choose which trigger you wanted to use to initiate the workflow.

Add Fetch

Configure the rest of your workflow (if you want additional steps prior to calling an API) or go directly to adding the Fetch action.

Click "Perform an action" to add the HTTP Fetch action.

HTTP Fetch Configuration

In the HTTP Fetch settings, specify the Model you want to use for the action and the URL of the webpage or endpoint to fetch. (You can also reference URLs found in prior actions/outputs by using a prompt or referring to trigger/action output data. A guide on how to do this is available here.)

Lindy supports all standard HTTP Methods. You can specify the Fetch Method in the "Method" field and the content type of the body in the "Content Type" field. If Detect is selected, the content type will be detected as JSON or XML automatically. If JSON or XML is selected, the body will be parsed and validated before fetching.

If you have any dynamic data you want Lindy to pass, add this as a prompt by setting the "Body" field to "AI Prompt" and instructing Lindy on what dynamic data to pass.

Note: Lindy currently doesn't support custom header configuration.

In the example below, Lindy is sending data to a Zapier Webhook.

The Body of the request uses an "AI Prompt" that instructs Lindy to write a poem about the user information received from the Webhook trigger.
