Hi Square team,

We have issue from Square.

The invoice_ids for each event are different. :slightly_smiling_face:

Dear Mr Brian,

I knew, there are 2 events with 2 invoices.

But you know 2 invoices has same “subscription_id”: “f688129f-f273-4937-a90f-14a24f784933” and time created very nearly

“event_id”: “23db8b83-7342-5d9c-bcf8-45c26451d543” => “created_at”: “2024-04-23T12:38:31Z”,

“event_id”: “5e2b4275-1c3f-5aae-8244-a37590817389” => “created_at”: “2024-04-23T12:38:41Z”,

And please note that we test on sandbox env And I ensure we only payment one time.
