MercadoPago

About MercadoPago

MercadoPago provides a developer API and reference documentation for integrating payment processing into applications. The reference covers authentication methods including OAuth (token creation and refresh via /oauth/token) and documents online payment functionality, including a "Checkout Pro" integration option.

The documentation is organized by topic, with sections for authentication and online payments, and is available in multiple languages including Spanish, Portuguese, and English. It targets developers building payment integrations, particularly those operating in Latin American markets given the region-specific site configuration (Brazil-based domain and site identifiers referencing multiple Latin American countries).

Key features

• OAuth token creation and refresh for authenticated API access
• Online payments API (Checkout Pro and related integrations)
• Structured API reference documentation with endpoint-level docs
