# Update Subscription

Update an existing Subscription resource, typically used for subscriptions created without a Subscription Plan. Note that you can only update specific resource fields.

Two common use cases for updating a Subscription are:

### Updating the payment amount

This operation allows for adjusting the payment amount, such as when a subscriber decides to donate more or less money to a charity or upgrade/downgrade a product or service.

### Updating billing details

If the subscriber wishes to change their payment details, you can update the buyer_details.instrument_id] property with a new [Payment Instrument.
