Chargebacks, invoices and receipts

- [Handle chargebacks](/accepting-payments/after-the-sale/handle-chargebacks): A chargeback is a payment the buyer's issuer takes back; the issuer decides. PayMe sends sale-chargeback (sale_status chargeback or partial-chargeback; inquiry_number, inquiry_code, card_last_four_digits, vas_3ds_exists) and emails the seller. The amount is taken from the PayMe balance; a handling fee may apply under the agreement and isn't returned automatically. Respond as the email describes, within its deadline; there is no chargeback API. A reversal sends sale-chargeback-refund. refund-sale on a charged-back sale returns 305. get-transactions lists chargeback rows.
- [Issue invoices and receipts for your sales](/accepting-payments/after-the-sale/issue-invoices-and-receipts): Automatic documents: with invoicing set up, a paid or captured sale issues a document and each refund a credit document. sale_invoice_url is in sale-complete and refund; the number comes later in get-sales sale_invoices. Skip one sale with services [{name: invoice, settings: {active: false}}]. Documents API (deprecated, contact partners@payme.io first): needs its own activation (703); POST /documents with doc_type, buyer_name, items; asynchronous, so GET /documents/{doc_id} returns 1005 until ready; authority_redirect_url means Tax Authority approval first.
