This has been 'under review' for 18 months. Any update?

We could really do with the ability to create Orders (and Subscriptions, Payments) exposed on the API too, to be able to sync purchases/sales from third party booking platforms into GHL. Would unlock so much more potential combined with the new custom objects features.

Generate Orders for Subscription Payments"

Request: Add functionality for subscriptions to automatically create a new order with each payment, especially for physical products. Currently, subscriptions only generate an initial order, making it difficult to fulfill recurring shipments. Without a new order tied to each payment, additional shipping labels cannot be generated since the entire process depends on the order workflow. This feature is essential for fulfillment of recurring physical product shipments.

Definitely need to be able to add subscription/recurring payment product to a contact via API, or at the very least be able to add a contact to a workflow to initiate a charge for a recurring payment product... right now automating recurring payment type products is really limited. No feature to automate this in workflows, can't use a custom form, no possibility to use an embedded form, leaving the only options being the limited 1-step/2-step forms. Each with its own limitations if not a super basic use case... The only other alternative is to utilize a payment link which has somewhat of a siloed use case/user experience. API access would allow for a custom code-driven form or custom call from a workflow, opening up more flexibility.

is there any api so i can add the subscription payment to customer

..?
