How can I authenticate HTTP GET requests in Webflow without custom code? Can Logic in Webflow be used to trigger server-side calls on page load and pass URL parameters to Logic? Is it possible to display the data returned from Logic in an HTML element within Webflow? Thank you!
TL;DR
- Webflow cannot authenticate HTTP GET requests or display returned data on page load without custom code.
- Webflow Logic only supports server-side flows triggered by forms, CMS events, or webhooks, and cannot send data to the frontend in real time.
You’re looking to authenticate HTTP GET requests, run them on page load with Logic, and display returned data—all without custom code in Webflow. Here's the reality based on Webflow’s current capabilities.
1. No Native Support for HTTP GET Authentication Without Custom Code
- Webflow does not natively support HTTP request authentication (such as passing API keys, tokens, etc.) purely through the Designer or Logic without custom code.
- To make authenticated requests, especially to external APIs, some form of headers (e.g.,
Authorization: Bearer xxx) are needed—which require custom code or third-party automation tools (like Make or Zapier).
2. Limitations of Webflow Logic for API Calls on Page Load
- Webflow Logic cannot be triggered by page load. Logic flows are currently triggered by:
- Form submissions
- CMS item updates or creation
- Webhook triggers
- This means it is not possible to trigger Logic with URL parameters on a page load natively within Webflow.
3. Data from Logic Flows Cannot Be Displayed Real-Time in Page Elements
- Logic flows run server-side and do not return data directly to the frontend for real-time display during a live page session.
- You also cannot bind Logic return data to HTML elements dynamically without code.
- Displaying dynamic API-returned data requires JavaScript and custom DOM manipulation, which falls outside Logic.
Summary
You cannot currently authenticate HTTP GET requests, trigger API calls on page load, or display returned data in Webflow without using custom code. Webflow Logic is limited to backend workflows triggered by forms, CMS changes, or webhooks, and it doesn’t support sending data back to the frontend for display. For such use cases, client-side JavaScript or external tools like Make or Zapier are necessary.
