Verifying the authenticity of a payout event is critical to preventing fraud.
Fusion offers a signature that can be checked to verify authenticity. Some publishers choose to implement IP whitelisting, though Fusion does not currently use a static IP, and this IP may change.
Securing the Redirects
We strongly recommend securing the link using a Hashkey. This will return appended to the completes redirect as “&asr_s_hash=”
For our Sha-1 hashing guidelines, please reach out to globalsupply@purespectrum.com
IP Whitelisting
We have 2 static IPs when implementing s2s postbacks:
