*** title: Whitelabel API slug: integration/api subtitle: A complete API solution for building custom on/off ramp experiences. max-toc-depth: 2 ---------------- The **Transak Whitelabel API** enables partners to integrate Transak products directly into their own platforms using APIs, without displaying any **third-party user interface** (such as the Transak Widget). Partners maintain complete control over the **user interface and end-to-end user journey**, while Transak manages the backend complexities through APIs, including KYC, compliance, liquidity, payment processing, and fraud management. ## Who Should Use This? This solution is ideal for partners who want to fully own and control the **E2E user journey**, **including the user interface, experience, and flow**.
Wallets
Integrate fiat on/off-ramps directly into wallet interfaces for seamless user experience.
DEXs or CEXs
Enable users to buy and sell crypto within your exchange platform using fiat.
DApps
Add fiat payment options to decentralized applications for broader user accessibility.
Fintech Apps
Power remittances, neobanks, and cross-border payment solutions with crypto rails.
## Key Capabilities Build and control the complete user journey, from authentication and KYC to order creation and tracking, without any third-party UI. Access 36+ cryptocurrencies across 45+ blockchains in 64+ countries with transparent pricing via Lookup APIs. Create and track orders programmatically using REST APIs, Webhooks, and WebSockets. Transak handles KYC, AML, transaction monitoring, and regulatory compliance. Reuse your existing KYC data with Transak through Sumsub for faster onboarding. ## Partner Integration Prerequisites Follow the steps in the [Need help in Integration](/getting-started/help-and-support#need-help-in-integration) section to reach us. Then raise the request to enable **Whitelabel APIs** for your API key and share your public IP addresses with Transak for whitelisting to use our APIs in your backend. Start by designing and implementing the complete user flow, including error handling. See the [Lookup API reference](/api/whitelabel/lookup/get-countries) to begin. You must include [Transak's Terms of Service](https://transak.com/terms-of-service) within their own Terms & Conditions. End users must be able to review and acknowledge Transak's T\&C as part of the user journey. ## Current Limitations & Known Constraints
