# Click API pro business

Click API is an interface to work remotely with Keitaro's campaigns. It allows to make requests and get responses from Keitaro on external websites.

# Differences from KClient PHP

KClient PHP is a ready client (an integration script) that is based on a Click API V3. KClient PHP already has the basic methods of the Click Api v3 work and the automatic click transfer and the description of the tracker's response.

# Click API requests

Campaign token should be sent while sending the requests to API. The token can be taken from the necessary campaign settings in the Click API token field on the left.

Make sure you use the correct prefix to access the client:

/click_api/v3/

The request and response examples:

curl "http://domain_tracker/click_api/v3?token=ebd928ea&log=1&info=1"
