DCS Response Parameters: A Review

Your DCS request must include d_rtbd=json if you want to receive a response from the DCS. The DCS will not return data if you omit this parameter. A basic call to the DCS to request data uses this syntax:

https://domain_alias.demdex.net/event?key1=val1&key2=val2&d_dst=1&d_rtbd=json&d_cb=callback

Sample Response

Recall that from the Send Data to the DCS documentation, the fictional company Acme, Inc. made this call:

https://acme_aam_domain.demdex.net/event?videoTypeID=2&data=moarData&d_dst=1&d_rtbd=json&d_cb=acme_callback

As this call includes the required response parameter, the DCS sent back the JSON object shown below. Yours may be similar or more complex.

{
    "stuff": [],
    "uuid": "22920112968019678612904394744954398990",
    "dcs_region": 7,
    "tid": "31ZpxW5bQGc="
}
