Print a receipt
The integration via API allows you to print two types of receipts: DTE and free printing, meaning bills or other types of receipts. Continue reading the instructions below to learn how to do it in each case.
Print a DTE (bill)
To request the printing of a bill with DTE, you need to make a POST call to {https://api-dev.redelcom.cl:20010/v2}/factura, replacing X-Authentication, clientId, and secret with your credentials.
curl
curl -X POST \
'https://api-dev.redelcom.cl:20010/v2/factura' \
--header 'X-Authentication: clientId;secret' \
--header 'Content-Type: application/json' \
--data '{
"dte": "XML de boleta o factura bajo el esquema de servicios impuestos internos",
"rdcTransactionId": "294-3727-16384",
"terminalId": "3127"
}'
| Field | Description |
dte | Required. Structure (XML) of the electronic invoice. You can find a complete XML example in the Annex: example XML for DTE printing. |
rdcTransactionId | Required. Code of the original payment request that you want to invoice. |
terminalId | Required. Code of the terminal to which the print request will be sent. |
If the call is successful, the printing will be generated on the selected terminal, and an empty response with a status code of 200 will be returned. If there is an error, the response will be one of the following:
| Status | Description |
| 401 | Invalid or nonexistent authentication. Verify your credentials. |
| 409 | There is already a pending print request. |
Free Printing
If you want to print a different type of document, such as a payment receipt or a preliminary bill, make a POST call to the API {https://api-dev.redelcom.cl:20010/v2}/impresion, replacing X-Authentication, clientId, and secret with your credentials.
curl
curl -X POST \
'https://api-dev.redelcom.cl:20010/v2/impresion' \
--header 'X-Authentication: clientId;secret' \
--header 'Content-Type: application/json' \
--data '{
