Working with GUI (Graphical User Interface) implementation means learning about many different APIs. Occasionally, an interesting API (Application Programming Interface) comes along that deserves further analysis and recognition. One of the most interesting in recent memory belongs to the travel service iVisa.
What Does the REST API Do?
This specific API creates one of the most innovative ways to check visa requirements anywhere in the world from a website or mobile application. As such, it represents an extremely exciting potential tool for travel companies wishing to provide greater convenience to their prospective customers.
With the REST API, iVisa partners can easily access an extensive database of visa requirement information. This will allow their users to check visa requirements for any combination of nationality and visited country in iVisa’s entire cache with just a few simple clicks or touches. Users can then request for their desired visa to be processed through iVisa’s main platform, after which they will be delivered via post or email.
iVisa’s API makes it easy for citizens of more than 220 countries to find the visa travel requirements they need for upcoming trips to any of 220 different destinations. The information delivered by the REST API comes out in JSON encoded form. JSON uses nested information, which makes grouping large amounts of information simple and allows for easier absorption.
A user wishing to know whether they need a travel visa for a certain destination simply has to provide the ISO country codes for their citizenship and the destination to which they are traveling. If you wish, this information can also allow iVisa to register your trip with the nearest embassy.
The Benefits of Using HTTP Authentication
Another interesting feature of the iVisa API is that it uses basic HTTP authentication instead of TLS. This allows for the restriction of access to certain functionalities, which ensures that they can only be used by authorized endpoints. These authorized endpoints may be used to check and see whether a visa is required for a particular trip, retrieve the fields necessary for processing the visa in question, handle payment, process the visa itself, and accommodate requests for visa status updates. Users who want to take advantage of these features must simply authenticate their requests.
Requiring authentication provides benefits for both users of the API and iVisa itself. It lets iVisa prevent abusive behavior, which keeps users protected and lets them use the API securely. It also provides valuable information to iVisa about how the API is being used for different applications. Gathering information in such a way allows iVisa to continue improving its API, providing its partners and their users with a cutting-edge way to verify visa requirements.
iVisa’s REST API provides one of the more interesting and broadly functional examples in the travel industry and represents a major leap forward in their industry. Whether you’re a techie or a traveler, be sure to keep an eye out for this tool on travel websites in the future, so that you can take your international trips with greater ease and save time applying for your visa.
