Cord bridges two worlds that speak different languages: Developers and Accountants.
This glossary resolves the most common ambiguities so that both teams can integrate the platform without friction.
Invoicing Terms (SAT)
CFDI (Comprobante Fiscal Digital por Internet)
It is the official XML file that represents an electronic invoice in Mexico. Cord issues CFDI version 4.0 automatically.
PUE (Pago en Una sola Exhibición)
Used when the collection of an invoice is made at the exact moment of issuance or before issuing it. If a customer pays via Credit Card on a Cord link, the generated invoice will be PUE.
PPD (Pago en Parcialidades o Diferido)
Used when the invoice is issued but the payment will be received at a future date (credit). PPD invoices always require a REP to be issued later when the money arrives in the account.
REP (Recibo Electrónico de Pago)
Also known as “Payment Receipt Supplement”. It is a secondary receipt issued to “settle” an original PPD invoice. Cord can automate the issuance of REPs when it detects the reconciliation of the bank deposit.
CSD (Certificado de Sello Digital)
These are the cryptographic files (.cer and .key) issued by the SAT that allow software to digitally sign invoices on behalf of a company. It is different from the FIEL (Advanced Electronic Signature). In Cord, you only need to upload your CSD.
CFDI Usage (Uso de CFDI)
A key from the SAT catalog that indicates what the recipient (customer) will use the invoice for (e.g., G03 - General expenses, I04 - Computer equipment).
Technical Terms (Developers)
Idempotency
It is the property of Cord’s APIs that guarantees that the same operation is not executed twice, even if the request is sent multiple times due to a network error. To achieve this, you send an Idempotency-Key in the headers of your requests. More information.
Webhook
It is a mechanism by which Cord proactively notifies your server (via an HTTP POST request) that an important event has occurred (e.g., quote.paid, quote.invoiced). More information.
Cord Elements
It is our suite of pre-built user interface (UI) components that you can embed directly into your application (React, Vue, or plain HTML) to process payments without having to design the checkout flow from scratch. More information.
Test mode
sk_test_ keys don’t consume your usage meter or count toward billing, so they’re useful for integrating the API without affecting your plan. Note: they operate on the same organization data (there’s no 100% isolated sandbox yet), and whether stamping is real or simulated depends on your Facturapi configuration.
Endpoint
A specific URL of the Cord API designed to execute an action (e.g., POST /api/v1/cotizaciones to create a quote).
B2B Financial Terms
Net-30 / Credit Terms
It means that the customer has 30 calendar days from the issuance of the invoice (or product delivery) to settle the total balance.
Dispute (Chargeback)
Occurs when an end customer contacts their bank to reject a charge processed via Cord. The bank temporarily holds the funds while Cord helps you submit evidence to win the dispute.
Reconciliation
The process of matching a money movement in the corporate bank account with its respective invoice or accounting record. Cord automates 95% of B2B reconciliation.
