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: 

  • [45.92.116.0/22]
  • [194.28.46.0/23]

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.

  • Hi there.

    The article is updated now with:
    1. Explanation as to who should use the list of IP addresses to register - ad networks receiving postbacks and app owners using push API.
    2. The IP addresses list was unified to a single list. You can copy it using the Copy button or download the list of IPs text on the bottom of the article.
    3. New IPs were NOT introduced, but a few IPs were removed from the list.

  • October 4, 2021: Significant changes have been made to the AppsFlyer IP address list. You must update your network edge device IP address allowlists (firewalls, and so on) before November 8, 2021.

  • October 5, 2021: We've had requests to provide the IP list as CIDR blocks. We've added an addtional CSV with the blocks. Note: This CSV contains 86 rows. Rows 1-2 contain CIDR blocks with multiple addresses. The remaining rows each reference 1 address (CIDR notation /32)

  • ***Action required *** You must update the AppsFlyer IP address list before November 8, 2021. As previously mentioned, on November 8, 202, we are adding two blocks of IP addresses that we will use to send Push API and postbacks to partners. If you implement security mechanisms that restrict sending data to your endpoints you must update the IP address list in your system. If you don't you may stop receiving all or some Push API messages and partners may stop getting postbacks. Update your systems now!

  • ***Action required *** Remember on November 8, 2021, we are adding IP addresses to be used by our servers to send Push API messages and postbacks to partners. Have you updated your security mechanisms? If not, please update your systems now.

  • ***Legacy IP addresses deprecation *** No immediate action required ***
    We previously (October 2021) added many addresses to our IP allowlist. Since then we have stopped using our legacy IP addresses and today we are announcing their deprecation. No immediate action is required. However, the best security practice is to remove the legacy addresses from your allowlist. Note! Allowlist only the addresses in these blocks [45.92.116.0/22] [194.28.46.0/23]. All other addresses should be removed from your allowlist.
