Server-to-Server Integrations

When retrieving or refreshing the ATS Envelopes, publishers integrating server-to-server are required to include the X-Forwarded-For header to ensure that the client-side IP address is within the approved countries tied to the ATS Placement.

For example:

cURL

curl --request GET \
     --url 'https://api.rlcdn.com/api/identity/v2/envelope?pid=14&it=4&iv=38CFDA7F9B55B7F74B6D3D143CBB7661DA9BFEB4683473A5813B220A571A1E37&ct=4&cv=CPUCbs9PUDXghADABCENCBCoAP_AAEJAAAAADGwBAAGABPADCAY0BjYAgADAAngBhAMaAAA.YAAAAAAAA4AA' \
     --header 'Origin: https://example.com' \
     --header 'X-Forwarded-For: 203.0.113.195' \
     --header 'accept: application/json'
