Hi Juliandika,

Combining two or more API is a big game terms of Development and Infrastructure. In order to achieve that, you must have the API access to multiple travel sites (ie, booking.com, hotels.com, expedia.com etc) which is quite a challenging job.  Most of the travel companies expect a working site with a good volume of bookings/month. There are other certain terms which makes the job almost impossible for the new affiliates obtaining the API access.

To the solution to it, You may go with some aggregator websites like, Travelpayouts.  You can apply for their API and can have your own customized price comparison website.  Or you can go with their Whitelabeling solution which is cost effective, easy affiliation programs and easy to maintain.

Here is how Whitelabeling theme looks like

TravelPayouts :

Demo : https://www.adivaha.com/wordpress-travelpayouts-theme.html

This theme is using Adivaha APIs and its services are limited to Adivaha only.  It’s checkout system makes it different in terms of the feature if compared to any price comparison website. Whereas in Adivaha theme, your visitors never leave your website at the time of checkout. Its helpful if you want to represent yourself as a BRAND similar to agoda, booking.com. Your customers will be able to register themselves and manage their bookings within the website.

Let us know if you have any more question.
