The IP addresses listed are controlled by and for the use of AppsFlyer. The list changes from time to time according to our capacity and operational requirements. We make every effort to make list changes infrequently.
AppsFlyer APIs provide attribution and reporting services to advertisers and partners. These services include:
- Sending postbacks
- Sending Push API messages
- Uploading Audiences
If you use network perimeter devices such as firewalls and proxy servers, you must ask your security team to allowlist AppsFlyer IP addresses as listed in this IP allowlist.
On February 16, 2022, we deprecated legacy IP addresses and removed them from the allowlist.
Allowlisted addresses use the following CIDR blocks:
Pull API and server-to-server (S2S)
Pull API and S2S aren't affected by the addresses listed in this article. However, verify that the *.appsflyer.com domain is allowlisted and isn't blocked in any way.
