Please go through the below 2 responses when I hit billing_info Clover Rest api. https://apisandbox.dev.clover.com:443/v3/apps/{Actual app Id}/merchants/{Actual merchant Id}/billing_info 1> For active merchant in Clover. Through Postman hit above Clover rest api got below response. { "appSubscription": { "id": "KFPS60ARP6KKL", "name": "Free", "amount": 0, "description": "Sample subscription", "active": true, "status": "ACTIVE", "plan": false, "subscriptionCountries": { "elements": [ { "id": "FC5QFAGETQQTW", "name": "Free", "amount": 0, "country": "US", "description": "Sample subscription", "active": true, "appSubscription": { "id": "KFPS60ARP6KKL" } } ] }, "app": { "id": "{AppId}" }, "label": "Free" }, "isInTrial": false, "billingStartTime": 1565345411000, "daysLapsed": 0 } ######## 2> For the merchant who cancelled the account/services/subscription from Clover. Through Postman when hit above Clover rest api got below response. { "message": "401 Unauthorized" } My question is whenever we get this "401 Unauthorized" in response for above Rest Api then can we consider merchant has been cancelled the account/services/subscription from Clover ?. So there is only need to check whether response is "401 Unauthorized" ? So that we will same Rest api in production environment also. Thanks in advance.
