Cost to Hire a Adyen API Developer
The cost of Adyen API development depends on the complexity of your implementation—from a basic hosted drop-in to fully custom marketplace and recurring payment flows.
Freelancers: $90 – $170 per hour. While some freelancers can get a basic integration running, many struggle with advanced workflows like fund splitting, KYC, and webhook reliability.
Agencies: $180 – $300 per hour. Many agencies charge premium rates but lack real-world experience with Adyen's platform-specific nuances like platform account setup and PCI compliance considerations.
Deploi: $100 per hour. As a remote-first team with senior talent and low overhead, we deliver enterprise-grade Adyen integrations at highly competitive rates. Our expertise spans multiple industries and payment architectures, which helps you reduce risk and time-to-market.
Adyen API Overview
Adyen provides a comprehensive suite of RESTful APIs for global payment processing, subscription billing, fund splitting, identity verification, and financial settlement.
Authentication uses API keys or OAuth tokens, with webhooks providing real-time updates on payment status, disputes, payouts, and compliance events.
The Adyen for Platforms offering enables marketplaces and platforms to handle onboarding, KYC, and payment splitting across sub-merchants—all through the API.
With developer tools like the API Explorer, test card numbers, Postman collections, and server-side SDKs for every major language, the platform is built for rapid implementation and developer velocity.
Adyen supports hundreds of global payment methods, local currencies, and fraud detection tools—making it a preferred solution for enterprise-grade commerce platforms.
What to Look for When Hiring Adyen API Developers

API Ecosystem Knowledge: Your team must be comfortable with Adyen’s entire stack—from payment processing to financial reporting and reconciliation.
