How to get a signature for hotels search API

The query shall be as follows:

http://engine.hotellook.com/api/v2/search/start.json?iata=HKT&checkIn=2015-06-10&checkOut=2015-06-13&adultsCount=2&customerIP=192.168.1.1&childrenCount=1&childAge1=10&lang=ru&currency=USD&timeout=20&waitForResult=0&marker=16886&signature=a9cf959983a2cdf88fc9012328c47494

With the following query parameters:

• iata=HKT;
• checkIn=2018-12-10;
• checkOut=2018-12-13;
• adultsCount=2;
• customerIP=77.111.247.75;
• childAge1 = 10;
• childrenCount=1;
• lang=ru;
• currency=USD;
• waitForResult=0.

Let’s sort them alphabetically:

• adultsCount=2;
• checkIn=2018-12-10;
• checkOut=2018-12-13;
• childAge1 = 10;
• childrenCount=1;
• currency=USD;
• customerIP=77.111.247.75;
• iata=HKT;
• lang=ru;
• waitForResult=0.

Next, fix the values of the assorted parameters using colons and add the affiliate security token and marker (they can be found in each partner’s personal account) before them:

WriteHereYourToken:WriteHereYourMarker:2:2018–12–10:2018–12–13:10:1:USD:77.111.247.75:HKT:ru:0

This string is used for signature creation. As a result, we have the following: 9961b6ecb56d45935667141b79cfbc28.

To create a query, take the query parameters, add the affiliate’s security token and marker, and fix using & into the search string:
