We used Authorize.Net PHP SDK to access API. Tried the createSubscription method (in https://developer.authorize.net/api/reference/index.html#recurring-billing) and we get api response as 'Subscription ID : 5132323'. And the webhook response as follows.

{"notificationId":"553bc363-fe7f-4f6a-9aa8-7e48e3909c88","eventType":"net.authorize.customer.created","eventDate":"2018-04-19T06:34:46.7732437Z","webhookId":"6122a7f7-73f1-4489-b059-7b9fa050eb99","payload":{"paymentProfiles":[{"id":"1503605810"}],"merchantCustomerId":"","description":"Profile created by Subscription: 5132353","entityName":"customerProfile","id":"1504293361"}}


{"notificationId":"639cb767-6d71-47d3-ad68-6bb05a4f4e93","eventType":"net.authorize.customer.subscription.created","eventDate":"2018-04-19T06:34:46.7732437Z","webhookId":"6122a7f7-73f1-4489-b059-7b9fa050eb99","payload":{"name":"Sample test2 Subscription","amount":4.30,"status":"active","profile":{"customerProfileId":1504293361,"customerPaymentProfileId":1503605810},"entityName":"subscription","id":"5132353"}}


{"notificationId":"e48d13b5-61b1-413d-a98a-4c2f1dd17b61","eventType":"net.authorize.customer.paymentProfile.created","eventDate":"2018-04-19T06:34:46.7732437Z","webhookId":"6122a7f7-73f1-4489-b059-7b9fa050eb99","payload":{"customerProfileId":1504293361,"entityName":"customerPaymentProfile","id":"1503605810"}}

The 'authcapture' event webhook response for the above 'createSubscription' is below.

{"notificationId":"c8d685a2-4442-4c58-8ccc-7e521038f905","eventType":"net.authorize.payment.authcapture.created","eventDate":"2018-04-19T09:07:26.8185032Z","webhookId":"6122a7f7-73f1-4489-b059-7b9fa050eb99","payload":{"responseCode":1,"authCode":"8JGO4H","avsResponse":"Y","authAmount":4.30,"entityName":"transaction","id":"40012883675"}}


The above Webhook response does not have any information to link for the 'Subscription ID : 5132323'.
Please let me know how can we track the paymenttransaction details from webhook for 'createSubcription'.

Thanks
