If you're experiencing issues with Zapier not adding 'https://' to URLs in Webflow collection items when the link field is missing it, resulting in Webflow publishing it as a subdirectory, there are a couple of possible solutions you can try.
Option 1: Adjust the Zapier Setup
1. Edit the Zap in Zapier that is causing the issue.
2. Locate the step where the link is being added to the collection item in Webflow.
3. Check if there is a formatting option or setting related to the link field. For example, you might find an option to add a prefix or configure URL formatting.
4. If there is such an option, enable it and set it to add 'https://' to the front of the URL. Save the changes.
Option 2: Use a Formatter in Zapier
1. Edit the Zap in Zapier that is causing the issue.
2. Locate the step where the link is being added to the collection item in Webflow.
3. Add a Formatter by Zapier step before the step that creates the collection item in Webflow.
4. In the Formatter step, select the text manipulation action that allows you to add 'https://' to the URL.
5. Configure the action to add 'https://' to the URL field.
6. Connect the output of the Formatter step to the input of the Webflow step.
7. Save the changes and test the Zap to see if the URLs are now correctly formatted before being added to the collection item in Webflow.
Option 3: Update the URLs in Webflow using a Collection List or Custom Code
1. Open your Webflow project and navigate to the Collection List or custom code where the URLs are displayed.
2. Review the code or setup of the collection list to identify where the URLs are coming from.
3. If you have control over the source of the URLs, ensure that they are already formatted with 'https://'. This can be done manually or automatically if you have access to the backend or database where the URLs are stored.
4. If you don't have control over the source of the URLs, you can use custom code in your Webflow project to add 'https://' to the URLs. This can be done using JavaScript/jQuery to target and modify the URLs before they are rendered on the page.
5. Once the URLs are correctly formatted in your project, republish your site and check if the issue with subdirectories is resolved.
Remember to test any changes or updates carefully to ensure they work as intended. If these solutions do not address your issue, it may be worth reaching out to Zapier support or the Webflow community for further assistance.
