Travel eSIM API
Global eSIM provisioning & management API.
About Travel eSIM API
A unified REST API to search, purchase, provision, and manage travel eSIMs programmatically — aggregating inventory from Airalo, Tourist eSIM, and regional carriers into one normalized endpoint. Ideal for OTAs, travel apps, and platforms wanting to embed eSIM as a high-margin ancillary product. Supports 190+ countries with instant QR code delivery, usage monitoring, and top-up.

}Common use cases
Here are the most common ways travel businesses use this API.
Show travelers an eSIM offer after flight or hotel booking — connected to Tourist eSIM and Airalo backends.
Embed eSIM purchase inside a travel wallet or super-app alongside currency, insurance, and visa products.
Launch a fully branded eSIM storefront at 15-30% lower pricing than direct Airalo rates.
Distribute eSIM products through travel agencies, OTAs, and corporate travel programs with bulk pricing.
Integration guide
Most teams are making live API calls to the sandbox within one hour of getting credentials.
Fill in the contact form and specify your product interest. Sandbox credentials are typically provisioned the same day.
Use our JavaScript, Python, PHP, Go or Java SDK — or call the REST API directly from any HTTP client. Full documentation available at /docs.
The sandbox environment returns realistic mock data for all endpoints. Test error scenarios, cancellations, and edge cases without any live bookings.
Your dedicated integration engineer reviews your code, tests edge cases, and ensures your integration is production-ready before go-live.
Swap sandbox credentials for production keys. Your engineer monitors the first 30 days of production traffic for any issues.
