Our API is organised around REST and lets you interact directly with Target Circle from anything that can send an HTTP request. Every API endpoint returns JSON encoded as UTF-8 and uses HTTP response codes to indicate errors.

The API host is api.targetcircle.com.

Authentication

Authentication is done via HTTP headers. X-Api-Token authenticates the endpoint with the API token for your account.

curl -X GET \
     -H "X-Api-Token : API_TOKEN" \
     "https://api.targetcircle.com/api/v1/offers"

For JavaScript usage, the API supports Cross-Origin Resource Sharing (CORS), so that you can use these headers in conjunction with XMLHttpRequest.

Parameters

Parameters are passed in the URL's query string. They must be properly URL-encoded using the UTF-8 encoding for non-ASCII characters. The plus character (+) is interpreted as a space and can be used as an alternative to %20. Arrays can be passed as a comma-separated string, for example: country=us,uk,no
