Yes, it is possible to insert JS code via the API in Webflow. The Webflow API offers several endpoints that allow you to interact with your site's code and content programmatically. By making API requests, you can create, read, update, and delete various elements within your Webflow site, including custom code. Here's how you can insert JS code using the Webflow API:

  1. First, you'll need to obtain an API token from Webflow. This can be done by navigating to your Webflow dashboard and going to "Project Settings" > "API Access". Generate a new token or use an existing one.

  2. Once you have your API token, you can use it to authenticate your API requests. Include the token in the "Authorization" header of your API request, using the Bearer authentication format.

  3. To insert JS code, you'll need to make a PATCH request to the appropriate endpoint. The specific endpoint depends on where you want to insert the code. For example, if you want to insert code in the "Head Code" section of your site's settings, use the /sites/{siteID} endpoint.

  4. In the request body, include the JS code you want to insert using the appropriate JSON format. For example, to insert code in the "Head Code" section, you would include the code inside the headCode field.

  5. Send the PATCH request to the Webflow API endpoint. If the request is successful, the code will be inserted into your Webflow site.

It's important to note that the Webflow API can be used to automate and extend the functionality of your site, but it requires technical knowledge and understanding of API concepts. If you're not comfortable working with APIs, you may want to consider using the Webflow Designer interface to insert JS code manually.
