Over time, inconsistencies emerged between Tatil Sepeti's website and mobile application. Through backend and mobile API development, we ensured that search results, discounts, and booking processes worked consistently across both platforms.
At a glance
Tatil Sepeti is an online travel platform offering hotels, flight-and-hotel packages, villas, and tours through its website and mobile application.
At Neon Apps, we worked on the backend and API services supporting the mobile app's search, booking, campaign, and third-party provider integrations. No screens were redesigned as part of the project. Instead, our work focused on ensuring that the existing interface received accurate and consistent data.

One service, two platforms, different results
The web platform served as the reference throughout the project. The product catalogue and booking business rules were already defined there. The challenge was ensuring that this information reached the mobile app accurately and completely.
A discount available on the website might not be applied in the mobile app. A search that returned results on the web could show fewer options or no results at all on mobile. Minimum-stay requirements behaved differently across platforms, room types were returned incorrectly for flight-and-hotel bookings, and accommodation packages from certain providers were unavailable in specific regions.


Scope of work
We developed the backend services required to support the villa module in the mobile application. These included services for the villa landing page, smart search, filtering, detail pages, banner management, frequently asked questions, campaign content, popular villas, search results, and booking flows.
We investigated inconsistencies between the website and mobile app and resolved them within the relevant backend services. We also fixed issues affecting third-party integrations used to provide accommodation packages.

Next steps
The backend services for the villa module have been completed. Migrating the mobile app's villa screens from their current WebView implementation to a native integration with these services is planned as a subsequent development phase under the responsibility of the Tatil Sepeti team.
For the favourites module, we conducted a technical analysis before development began. Rather than a completed feature, this work resulted in a development plan outlining the next steps, which was shared with Tatil Sepeti's product owner for review.
