Preview Deployment Protection

Problem: When Deployment Protection setting is enabled on Vercel, it’s not possible to trigger and complete a workflow run on a preview deployment. Solution: Vercel provides a way to bypass this protection by using a bypass secret. To create one, follow these steps:
1

Settings

Go to Deployment Protection section under your Vercel project settings.
2

Find related section

Click on Add Secret under Protection Bypass for Automation section.
3

Generate a bypass token

Don’t forget to save it.
Now that you have a bypass token, you can add it to your workflow URL as a query parameter. Imagine that you have a Vercel Preview and there is a workflow endpoint at https://vercel-preview.com/workflow. You can call the workflow like this in preview: 
curl -X POST \
  'https://vercel-preview.com/workflow?x-vercel-protection-bypass=<PROTECTION_BYPASS_SECRET>' \
  -d 'Hello world!'
