Hello,

You can utilize the pre-fill embed code feature to pass dynamic UTM parameters or FCB FBP data to the checkout page. By doing so, when a customer subscribes to a plan, the hidden custom field data will be available in the Subscriptions -> Custom field section.

If you wish to utilize this information for further purposes, you can access the same data within the Subscription Activate & Payment Successful webhook event. For more detailed instructions, please refer to the pre-fill documentation available at:
