Hi @avi91, @AmyLy I once responded to a similar question: https://community.zuora.com/t5/Subscriptions/How-to-activate-a-pending-acceptance-subscription-in-SOAP-REST/m-p/21703#M707 In the link above, I explain how to set the date in ContractAcceptanceDate, but the same operation is possible when setting the date in ServiceActivationDate. That is, ServiceActivationDate can be updated using the following Endpoint and Request: [PUT] https://rest.apisandbox.zuora.com/v1/object/subscription/{Target Subscription's Id} (For Example: https://rest.apisandbox.zuora.com/v1/object/subscription/2c92c0f86103a992016103fe5fd175aa) Request Body: {
"ServiceActivationDate": "2018-08-15"
} Note: The field name of Key is ServiceActivationDate. Although it may be possible by the method AmyLy mentioned, it is easier to use this Endpoint. ---- Additional Notes for @avi91 This is not an essential indication. But I tell you. You are using "https://apisandbox-api.zuora.com/rest/" as an endpoint. No problem. This Base URL works correctly. But, in fact, this Base URL is legacy one. Currently, it is better to use "https://rest.apisandbox.zuora.com/" as described in the REST API Reference. https://www.zuora.com/developer/api-reference/#section/Introduction/Endpoints
