Advanced HTTP with Zapier API Request actions

The Zapier API Request action lets you send raw HTTP requests to many apps so you can build flexible, low-code workflows when standard triggers and actions are not enough.

This how-to explains how the feature works, how to configure every field, and how to safely test requests inside your Zaps.

What the Zapier API Request action does

The API Request action is a beta feature that gives you direct access to an app’s HTTP API from within Zapier. Instead of only using predefined Zap actions, you can call specific endpoints and pass custom data.

With this feature, you can:

  • Send GET, POST, PUT, PATCH, or DELETE requests.
  • Target any supported API endpoint available through Zapier’s app integrations.
  • Control headers, query string parameters, and request bodies.
  • Use data from earlier Zap steps to build dynamic requests.

This option only appears for certain apps that support it. When it is available, you will see an action labeled similarly to API Request (Beta) in the action event list.

When to use the Zapier API Request feature

Use the Zapier API Request action when you need to go beyond the standard actions for an app. Common cases include:

  • Calling an API endpoint that has no native Zap action yet.
  • Using advanced filters or parameters that are not exposed in regular actions.
  • Working with experimental or beta endpoints provided by an app’s API.
  • Quickly testing a new integration pattern without building a full custom app.

Because this Zapier feature sends raw HTTP requests, you should also be comfortable reading the app’s API documentation and understanding basic request formats.

How to add a Zapier API Request action to your Zap

Follow these steps to insert the API Request action into a Zap:

  1. Open your Zap in the Zap editor.

  2. Choose the app you want to connect to using Zapier.

  3. In the list of events, look for an option named like API Request (Beta) or similar.

  4. Select that action event and click Continue.

  5. Connect or select your account for the chosen app, then proceed.

After this, Zapier displays the API Request configuration screen, where you can define the method, URL or path, and other request details.

Configure your Zapier API Request

The API Request configuration differs slightly depending on how the app is implemented on Zapier, but the core options are similar. You will usually see fields for the request method, endpoint, headers, and body.

Choose the HTTP method in Zapier

The method defines the type of HTTP operation. In most Zapier API Request actions, you can choose from:

  • GET – retrieve data from an endpoint.
  • POST – create a new resource or submit data.
  • PUT – replace an existing resource with new data.
  • PATCH – update part of an existing resource.
  • DELETE – remove an existing resource.

Check the app’s API reference to confirm which method is required for the endpoint you want to call.

Specify the endpoint or URL in Zapier

Next, provide the endpoint path or full URL. What you see depends on the specific app’s Zapier integration:

  • Relative path field: some apps provide a base URL and ask only for the path, such as /v1/contacts.
  • Full URL field: other apps require the complete URL, including the base, such as https://api.example.com/v1/contacts.

In either case, you can insert data from previous steps using the Zap editor’s insert-data menu. This lets you dynamically build things like resource IDs or query parameters.

Add query string parameters

Certain apps expose query parameters through dedicated fields within the Zapier interface. When these are available, you can add or map values without manually editing the URL. If they are not exposed, you can still include query parameters directly in the path or URL, for example:

/v1/contacts?status=active&limit=50

Always check the app’s documentation to see which query parameters are supported and how they should be formatted.

Set headers for your Zapier HTTP call

Depending on the specific app implementation in Zapier, you may have a dedicated area to define headers, or headers may be handled automatically based on your authentication.

Common header types include:

  • Content type, such as Content-Type: application/json.
  • Custom headers required by the target API.
  • Versioning or feature flags, if the API uses them.

Authentication headers are often added automatically by Zapier once you connect your account, so you typically do not need to provide them manually. Refer to the app’s API docs to see if extra headers are required.

Define the request body in Zapier

For methods like POST, PUT, or PATCH, you usually need a body. The API Request interface may offer:

  • Key–value pairs fields for form-style requests.
  • Raw body fields where you can paste JSON or another supported format.

When using a raw JSON body, ensure that:

  • Your JSON is valid and properly closed.
  • Field names match the API documentation exactly.
  • Values mapped from previous Zap steps are placed in the correct positions.

The way Zapier encodes this data depends on the app’s configuration; consult the connected app’s docs to confirm whether it expects JSON, form data, or another content type.

Use data from previous Zapier steps

One of the most powerful aspects of the API Request action is the ability to include data from earlier steps in your Zapier workflow. For example, you can:

  • Insert values from a trigger, like a new form submission.
  • Reuse IDs or URLs from earlier actions to update existing records.
  • Combine multiple pieces of information into one structured body.

Use the insert-data dropdown in the Zap editor to map fields into any part of your request: URL, headers, query strings, or body content.

Test your Zapier API Request

After you configure the API Request, you should test it before turning your Zap on.

  1. Click Test step in the Zap editor.

  2. Zapier sends the HTTP request using your configuration and account connection.

  3. Review the response details: status code, headers, and returned data.

  4. Adjust the method, URL, headers, or body if the response indicates an error.

Use the response output as input for later actions in the same Zapier workflow. You can map returned data fields into subsequent steps just like any other action output.

Troubleshooting Zapier API Request actions

If your request does not behave as expected, use this checklist:

  • Confirm the HTTP method matches the API’s requirements.
  • Verify the endpoint path or URL, including any path parameters.
  • Check that authentication is configured correctly in your Zapier connection.
  • Validate any JSON bodies using an external JSON validator.
  • Review the response body from the test step for error codes or messages from the API.

Because each app integration can handle details differently, always compare your Zap configuration with the official API reference for that service.

Where to learn more about Zapier API Request

You can find the official help article for this beta feature in the Zapier documentation: Make raw HTTP requests with API Request actions (Beta). That resource provides the most up-to-date behavior, limitations, and app-specific notes.

If you are planning complex workflows that rely heavily on HTTP calls, it can be helpful to work with automation and integration specialists. A consultancy such as Consultevo can assist with designing robust architectures around Zapier and related tools.

Once you are comfortable with the API Request action, you can extend your existing automations, experiment with new endpoints, and unlock more advanced use cases without needing a full custom integration.
