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 allowlist AppsFlyer IP addresses contained in the CSV.

  • Date of the most recent change to the IP list: October 4, 2021
  • CSV downloads
    • IP address list 
    • CIDR block list.
      There are 2 blocks containing multiple addresses and 84 blocks containing one address each. The multiple address blocks are: 
      • [45.92.116.0/22]
      • [194.28.46.0/23]
      • In early 2022 we will deprecate addresses that aren't part of these blocks. 

AppsFlyer IP addresses

The IP addresses listed are controlled by and for the use of AppsFlyer. The list changes from time to time in accordance with our capacity and other operational requirements. We make every effort to revise this list as infrequently as possible.

Server-to-Server
If you implement server-to-server (S2S) messages, allowlist incoming messages from AWS IP addresses so that you are able to receive endpoint response messages.

  • 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 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!
