### Payload
Each delivery is an [Event](/business/nouns/event) record. `data` holds what [PaymentSource.add](/business/nouns/payment-source/add) returns.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `name` | `string` | Yes | `PaymentSource.added`. |
| `at` | `datetime` | Yes | When it happened. |
| `seq` | `integer` | No | Its position in the namespace, one more than the Event before; any seq is a cursor into the history. |
| `data` | `json` | Yes | The Thing as the Action left it. |
| `data.paymentSource` | [Payment Source](/business/nouns/payment-source) | Yes | The saved Payment Source; Stripe holds its details. |
| `data.paymentSource.kind` | `string` | Yes | How it pays: a card, a bank debit from the Customer’s account, or a wallet on the Customer’s phone or browser. |
| `data.paymentSource.label` | `string` | Yes | What the Customer sees, such as the card brand and last four digits; never the full number. |
| `data.paymentSource.expiresOn` | `date` | No | When a card expires; the billing portal asks for a new one 30 days before. |
| `data.paymentSource.default` | `boolean` | No | True for the one Payment Source that new Invoices and renewals charge. |
| `data.paymentSource.removedAt` | `datetime` | No | When the Customer removed it; nothing charges it after, and the record stays. |
