# Subscriptions no longer support modifying the source parameter directly ## What’s new Subscription endpoints no longer support the `source` parameter. If you want to change the default source for a customer, use the [Source creation API](https://docs.stripe.com/api.md?api-version=2024-06-20#create_source) to add the new source, and then the [Customer update API](https://docs.stripe.com/api.md?api-version=2024-06-20#update_customer) to set it as the default. ## Impact This change removes the ability to directly update a subscription’s payment source through subscription endpoints. You must now use a two-step process: first adding a new source through the Source Creation API, then updating the customer’s default source using the Customer Update API. This modification might require significant updates to existing code that manages subscription payment sources ## Upgrade #### REST API 1.
