The import audience API is used to either add or remove devices from an audience. The API has the structure shown in the example. Use the procedure that follows to generate the API request URL and the API request body.

API request URL

https://hq1.appsflyer.com/audiences-import-api/{action}?api_token={api_token}

API request body

{
 "import_key": "{mport_key}",
 "platform": "{plaform}",
 "devices": [
             "{device}",
             "{device2}",
             "{devicen}"
            ]
}

 Before you begin:

• Ensure that you have created the audience in AppsFlyer.

To prepare an API request URL:

1. Go to Integration > Audiences.
   The Audiences window opens.
