Integrating REST APIs with Zapier: A Step-wise Guide for Seamless Automation

Published on Feb 28th, 2024

Integrating with REST APIs has never been easier than with Zapier, a powerful automation tool that connects over 2,000 apps. Here’s how to use REST APIs with Zapier to streamline workflows and boost your productivity manifold.


Step 1: Choose Your Trigger App


Start by selecting the app that will trigger your Zap. This could be any event like a new email in Gmail or a new row in a Google Sheet.


Step 2: Set Up Your Action


Once you have your trigger, choose the action that should happen next. For using a REST API, select the 'Webhooks by Zapier' action with the 'Custom Request' option.


Step 3: Configure Your Request


In the 'Custom Request' setup:



  • Method: Choose GET, POST, PUT, DELETE, or any other HTTP method your API requires.

  • URL: Enter the endpoint of your REST API.

  • Data: If needed, provide the necessary data in JSON or form-encoded format.

  • Headers: Add any required authentication tokens or content-type headers.


Step 4: Test Your API Request


Zapier provides an in-app test feature for you to confirm that your REST API integration works as expected. If successful, it will show you the data it received as a response.


Step 5: Activate Your Zap


With the successful test, name your Zap and turn it on. Your integration is now live, and your workflow is automated using your REST API.


Best Practices & Tips



  • Authentication: Securely store API keys or tokens using Zapier’s built-in authentication.

  • Error Handling: Make sure to handle any potential errors in your Zap logic for a robust integration.

  • Monitoring: Keep an eye on your Zap's activity logs to ensure everything is running smoothly.


With these steps, you're no longer just a user of apps but a creator of automated solutions that save time and eliminate mundane tasks. Zapier and REST APIs: a partnership for productivity.
