Accept-Language is now supported in the traffic

On the 20 January 2017

New feature is available for our traffic: you can set what languages the visitors’ browsers will support.
So for example if you buy traffic from Spain and your website is in Spanish it would be very natural if your visitors spoke Spanish and in your project’s settings in the HTTP Accept-Language field you should put es-es.
If you purchase traffic from Chile, Mexico or any other Spanish speaking country you would want to put es-cl or es-mx according to the country you receive the traffic.
At the same time you can use multiple languages in the project, just place them one per line as following example:

We have gathered almost all the available languages that you can use in your project in the table below:
