Integrating Mercado Pago connects cards and account balances to the rest of your operations. A payment can trigger a sale, reserve a place, grant access, issue a receipt, update a status or require handling an exception.

Start with what happens after payment

Should you reserve a spot, grant access, issue a ticket, notify an administrator or update inventory? Each answer changes the design.

Parts of the flow

  • Create a payment intent with enough information.
  • Direct the customer to a clear payment experience.
  • Receive notifications from the payment provider.
  • Check and store the actual transaction status.
  • Prevent the same event from being processed twice.

A common mistake

Relying entirely on the customer returning to the site. The system needs to know if a customer pays and closes the tab. That makes notifications and reconciliation central to the design.

What to review before integrating

Review possible statuses, cancellations, retries, refunds, internal traceability and who handles a flagged payment. Exceptions are part of payment operations.
