Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/crocoblock/jfb-gateway-subscription/archive/refs/heads/main.zipThis addon registers a new "Cancel Subscription" action for JetFormBuilder forms. The paid addon "PayPal Recurring Payments" otherwise this addon is useless.
Usage
Saving subscription ID
Add hidden field with "Field value": - Gateway Subscription ID. This field will store the ID of the newly created subscription. https://jetformbuilder.com/features/jetformbuilder-how-to-set-recurring-paypal-payments-in-wordpress-form/#how-to-create-form-with-plans

You can then use this field to save to your entity. It can be both a regular post and a user, CCT. There are corresponding actions for them - Insert/Update Post, Update User and Insert Custom Content Type.
Cancel subscription
Adjust the preset depending on which entity you want to store the subscription ID.
After that, select this field in the "Cancel Subscription" action
