Create and issue an invoice

This API lets you create and sign-and-issue an invoice in a single step (HSM signing). The invoice is officially issued as soon as it is created successfully.

POST

URLhttps://open-api.tingee.vn/v1/e-invoice/create-and-issue

Create, sign and issue an invoice in a single step (HSM signing).

Header Request

Header	Required	Description
`Content-Type`	✓	`application/json`
`x-client-id`	✓	Partner identifier issued by TINGEE.
`x-signature`	✓	HMAC SHA512 authentication signature. See How to generate the signature.
`x-request-timestamp`	✓	Time the request is sent (format: `yyyyMMddHHmmssSSS`, UTC+7)

Body Parameter

The body is identical to the Create a draft invoice endpoint (CreateInvoiceDto): it includes the invoice information fields, the buyer information (including buyerIdentity and buyerIdType), the items[] list and taxRateSummaries[].

See the full parameter table at Create a draft invoice — Body Parameter.

The example above is the result with the SInvoice provider. Depending on the provider, some fields may be empty ("") or not returned.

Field	Type	Description
`code`	string	Status code.
`message`	string	Result message.
`data.invoiceCode`	string	Invoice code.
`data.trackingCode`	string	Tracking code / transaction code at the provider (SInvoice: `transactionUuid`, same as `invoiceCode`; XCyber: `magiaodich`; MISA: `TransactionID`; BKAV: lookup code `MTC`; HiLo: `fkey`).
`data.invoiceNumber`	string	Official invoice number (after signing). For BKAV, the value consists of the invoice symbol + invoice number.
`data.reservationCode`	string	Secret lookup code (SInvoice) or `RefID` reference code (MISA). Not returned for other providers.
`data.codeOfTax`	string	Code issued for the invoice by the tax authority (XCyber, SInvoice, HiLo). Empty for MISA, not returned for BKAV.
`data.url`	string	Invoice lookup link (XCyber: link returned by the provider; SInvoice: lookup link by tax code and secret code; HiLo: generic lookup page). Empty for MISA, not returned for BKAV.

Common error codes

Code	Description	How to handle
`2034`	The invoice has already been issued successfully	Do not resend; use a new invoice code, or call Download invoice / Send email for the issued invoice.
`2032`	No default provider account is configured	Create an account with `isDefault = true`, or pass `accountId`.
`1057`	No account found for `accountId`	Check `accountId` with List accounts.
`2038`	The provider does not support the item type (`itemType`)	XCyber does not support `itemType` 2/6/7; HiLo and MISA do not support 6/7; BKAV does not support 6.
`1095`, `1096`	Master Merchant `merchantId` error	Pass the `merchantId` of a sub-Merchant belonging to the Master Merchant calling the API.
`90`, `91`, `92`, `97`	Request authentication error (timestamp, client-id, signature)	See System error codes.
`Others`	Other errors	See Error codes.
