What is the cleanest method in Webflow to invoke a GET API on button click without the ability to add custom code or an API call in the button settings?

To trigger a GET API request on button click in Webflow without using custom code or button API settings, your cleanest no-code option is using Webflow Logic (if available to your plan).

1. Use Webflow Logic for No-Code API Calls

• Webflow Logic provides built-in tools to handle workflows such as sending HTTP requests after a trigger (like a form submission or a CMS event).
• While buttons alone can't directly start a Logic flow, use a form block with a hidden field and a submit button instead of a standard button.

2. Simulate the Button with a Form Submission

• Place a form element in your design. Style it like a button if needed.
• Add a hidden input field (optional) for passing parameters or context.
• Style the submit button to match your desired button look.
• Rename the form action to something like "Trigger API GET."

3. Create a Webflow Logic Flow

• Go to Logic > New Flow.
• Set the trigger to Form submission from the form you just created.
• Add a "Make HTTP Request" step.
• Set Method to GET.
• Enter the API endpoint URL.
• Add headers or query parameters if needed.

4. (Optional) Add Further Logic Steps

• Handle success/failure results by chaining conditions (e.g., send a success message, update CMS, send email).
• You cannot modify the current page UI from Logic—only server-side actions are available.

5. Test the Functionality

• Publish the site.
• Click the styled “button” (form submit).
• Make sure the API is hit and verify the response (via backend or API logs, if applicable).

Summary

To trigger a GET API call on button click without custom code, use a Webflow form submission connected to a Logic flow. It's the cleanest no-code solution currently available in Webflow for this purpose.
