Updating the User's Free to Paid Group via Webhook

I’m getting payment confirmations from Membership through a webhook. I opted against using Stripe and PayPal’s native support due to various limitations I observed.

However, I’m encountering difficulty updating the user group from free to paid using logic. Is this possible? Am I overlooking something? I couldn’t find an option to identify the user through Webflow data. It seems like user selection is static (requiring manual email entry).

Logic has too many limitations here, I would advise using Make or another automation platform instead that has direct Webflow API access capabilities.

You’ll need the UserID however, which is hopefully included in the order webhook.
