Overview

Use the setSubscriptionCustomer method. 2Checkout moves subscription under the customer for which you provide the 2Checkout customer reference or the External customer reference during the subscription update process.

Requirements

To move a subscription from a source customer to a target customer:

• Use 2Checkout customer references or External customer references belonging to the target customer. 2Checkout re-assigns the subscription to the target customer. 
• Customer references must be valid and associated to the target customer entity under which you move the subscription.
• If you provide both the 2Checkout customer reference and External customer reference they need to belong to the same target customer entity.
