It is not a resolved or validated affiliate ID; COPE resolves and validates attribution downstream. | | `line_items` | yes | `array` | - | - | | | `occurred_at` | yes | `string` | - | - | | | `order` | yes | `object` | - | - | | | `order_overview_url` | no | `string` | - | - | | | `payment` | no | `object` | - | - | | | `payment_method` | yes | \`object | null\` | - | - | | `phone_offer_id` | no | \`string | null\` | - | Phone offer identifier associated with this sale, if any. Raw attribution signal only. | | `promo` | yes | \`object | null\` | - | - | | `promo_code` | no | \`string | null\` | - | Promo code applied to this sale, if any.

It determines which document the buyer is owed — COPE is deemed supplier for an ESS sale and issues an invoice and credit note; for a non-ESS sale it is a payment agent and issues a payment confirmation and refund receipt. Absent means a producer that predates the field; consumers fall back to the invoice rather than silently downgrading a document. Deliberately not an enum so a new classification cannot reject events against an older schema. | | | `totals` | yes | `object` | - | - | | | `vat_mode` | no | `string` | `cope_vat`, `creator_vat` | Which party is liable for VAT on this sale: COPE (`cope_vat`) or the creator (`creator_vat`). | | | `vat_responsibility` | no | `string` | `cope`, `creator` | Which party remits VAT to the tax authority. | | ## Example CloudEvent ```json theme={"theme":{"light":"github-light","dark":"github-dark"}} { "data": { "business": {}, "buyer": {}, "event_type": "payment.dispute.opened", "line_items": [ { "amounts": { "gross_cents": 1000, "net_cents": 1000, "tax_cents": 1000, "tax_percentage": 19 }, "is_trial": true, "payment_number": 1000, "product": {}, "quantity": 1000 } ], "occurred_at": "2026-05-05T12:00:00.000Z", "order": { "created_at": "2026-05-05T12:00:00.000Z", "currency": "EUR", "source": "example_source" }, "payment_method": {}, "promo": {}, "schema_version": "1.5", "totals": { "product": { "gross_cents": 1000, "net_cents": 1000, "tax_cents": 1000 }, "total": { "gross_cents": 1000, "net_cents": 1000, "tax_cents": 1000 } } }, "datacontenttype": "application/json", "dataschema": "https://schemas.cope.com/events/payment.dispute.opened/v1", "id": "payment.dispute.opened:example", "idempotency_key": "payment.dispute.opened:example", "source": "cope.payment", "specversion": "1.0", "subject": "dispute:example", "time": "2026-05-05T12:00:00.000Z", "type": "payment.dispute.opened" } ``` ## Compatibility Fields may be added within the same major version.
