This topic provides an outline on using the Zuora SOAP and REST APIs to update products on subscriptions, even with future-dated amendments.

You can use Zuora SOAP API and REST API to update a product even when future-dated Update Product amendments already exist on the subscription:

• For SOAP API, use the SpecificUpdateDate field on the Amendment object, see the Create an UpdateProduct Amendment Before a Future-dated Update use case.

• For REST API, use the specificUpdateDate field in the Update subscription method.
