Forms are the lifeblood of most websites. Whether it's a contact form, newsletter signup, or order request, they're essential for capturing user data. But what happens next? Typically, form submissions just sit in your inbox—or at best, get stored in a database.

What if you could automatically send that data to tools like Google Sheets, Slack, Salesforce, or HubSpot—without writing a single line of code?

In this post, we’ll show you how to connect any website form to an API in minutes using a no-code tool: ContactFormToAPI.

Why Connect a Form to an API?

Integrating your form with an external API helps you:

Automate workflows (e.g., send form leads to CRM)

Avoid manual copy-pasting

Improve response time and data accuracy

Trigger third-party services (e.g., SMS, email, analytics)

This used to require developer help—but now, it doesn’t have to.

The No-Code Solution: ContactFormToAPI

ContactFormToAPI is a powerful no-code tool that lets you connect any website form to any REST API—no plugins or scripts required.

It works with:

WordPress (including Contact Form 7, WPForms, Elementor forms)

Webflow

Squarespace

Static HTML/CSS/JS sites

Shopify and more

Whether you want to send form data to Google Sheets, HubSpot, Airtable, Notion, Discord, or your custom API, this platform makes it easy.

Step-by-Step Guide: How to Connect a Form to an API (No Code)

Step 1: Identify Your API Endpoint

First, figure out where you want to send the form data. Examples include:

A CRM’s REST API (e.g., HubSpot, Salesforce)

Google Sheets via Web App

A webhook URL from a platform like Slack or Make.com

Your custom backend API

Make sure the API accepts POST requests and provides documentation or field structure.

Step 2: Create an Account on ContactFormToAPI

Go to https://www.contactformtoapi.com
Create a free account

Click **"Add New Integration"

**
Enter your destination API URL

Step 3: Map Your Form Fields

Enter your form’s field names (like name, email, message)

Map them to the API’s expected field names

Choose the format (JSON, form-data, etc.)

Add headers if needed (e.g., API key or authorization token)

Example:

{

"firstName": "{{name}}",

"email": "{{email}}",

"message": "{{message}}"

}

The tool automatically replaces {{name}} with the real form input.

Step 4: Add the Provided Endpoint to Your Form

ContactFormToAPI gives you a custom endpoint to use as your form’s action URL. You’ll now replace your form’s default action with this.

Example:

</form>

For WordPress users, this can be added inside the Contact Form 7 settings or through shortcode modifications.

Step 5: Test Your Integration

Submit a test form and monitor the response in:

Your API destination (e.g., Google Sheets, CRM)

ContactFormToAPI’s dashboard (response logs, errors)

You can also configure error handling, fallback URLs, or conditional logic from the platform.

Supported API Integrations

You can connect your form to almost any service, including:

Platform	Supported via
Google Sheets	Web App/API
HubSpot	Forms API
Salesforce	Web-to-Lead
Airtable	REST API
Notion	API v1
Slack	Webhooks
Email Services	Mailgun, SendGrid

You can also integrate with tools like Make, Pabbly, or n8n if you need workflow logic.

Is It Secure?

Yes. ContactFormToAPI uses HTTPS, token-based authentication, and does not store your data unless you configure logging. It's GDPR-compliant and designed to meet modern security standards.

Who Is This For?

This solution is perfect for:

Marketers who want to automate without dev help

Developers who want to avoid writing boilerplate code

Business owners who use multiple online tools

Agencies managing multiple client sites

Final Thoughts

Integrating your website form with external services no longer requires technical expertise. Tools like ContactFormToAPI make it effortless to send form data to any API—without plugins, coding, or complicated setups.

If you're tired of your form submissions sitting idle or being manually processed, it’s time to automate your workflow.
