Mercado Pago AWS Integration
Budget: $1,500 – $3,000 USD
I need a GeneXus developer who works in Java/Tomcat to wire my application to Mercado Pago using the official SDK and expose the logic as a secure REST service on my AWS instance.
Scope
• Implement Checkout, Refunds and Webhooks flows end-to-end.
• Persist all operational data in a fresh MongoDB database that you provision on the server.
• Protect every endpoint with HTTPS by installing a Let’s Encrypt certificate and handling auto-renewal.
• Keep keys, tokens and other secrets outside the codebase via AWS environment variables or Parameter Store.
• Deploy the compiled GeneXus Java build to Tomcat, validate in Mercado Pago sandbox, then switch to production mode.
Deliverables
1. Source code plus GX objects, clearly commented.
2. Shell/CloudFormation scripts (or concise manual steps) for server setup, SSL installation and DB provisioning.
3. Postman collection showing the three payment flows.
4. A brief security checklist covering headers, CORS and IAM roles.
5. Handover session where we run through refunds, webhook verification and checkout on live credentials.
AWS, Mercado Pago SDK, REST, SSL/TLS and server-hardening experience are all mandatory. If you have shipped a similar integration before, please mention it along with links or screenshots.
