Hello there, I will integrate the Viva API for SEK and EUR processing — handling merchant profile configuration, currency routing, and transaction verification — along with clear documentation for adding currencies later. One key detail: I will set up separate payment sources per currency within Viva so each transaction routes to the correct acquiring bank, avoiding forced conversions and unexpected FX fees for your customers. Questions: 1) Are you using Viva Checkout or their Native Checkout SDK? 2) Do you have a Viva merchant account already, or does that need setup too? Looking forward to discussing further. Best regards, Kamran

Hi, I've worked extensively with the Viva Wallet API for payment processing and have hands-on experience configuring multi-currency merchant accounts across European markets, including SEK and EUR. For your project, I'll set up the API integration with proper currency handling, ensuring each transaction correctly routes through the appropriate currency configuration using Viva's source and terminal architecture. I'll implement secure authentication via OAuth2, configure webhook notifications for real-time transaction tracking, and handle all edge cases around currency-specific formatting and settlement. You'll also receive clean, detailed documentation covering the full setup, API flows, and maintenance guidelines so your team can scale to additional currencies independently. I can start immediately.

Hello, I can build and integrate the secure middleware required to connect your platform with the Viva API. Since you need to process transactions natively in both SEK and EUR, the most critical challenge is ensuring the API bridge handles currency routing securely without exposing your core infrastructure to financial data leaks. I will construct a dedicated API gateway to manage these transactions safely. I will develop the integration using Go and containerize the service using Docker so it runs completely isolated from your main application. This architecture ensures high security and easy auditing. I have built secure middleware for bridging complex APIs before, and I will write clear documentation covering the endpoint architecture and deployment steps so your team can maintain it easily. I guarantee that if I cannot get the multi currency Viva transactions working flawlessly in your test environment, I will not charge you for the project. Best, Ahmad

Hi there, I will integrate Viva for SEK and EUR with order creation per currency (ISO 752/978), webhook handler with HMAC signature verification, and a setup brief covering keys and webhooks. Pitfall to flag: each currency needs activation on the Viva merchant dashboard before the API accepts it, plus a separate Source ID per currency for correct settlement. Questions: 1) Are SEK and EUR already activated on the Viva dashboard, or part of scope? 2) What stack does this integrate into (PHP, Node, .NET)? Looking forward to talking through the details.
