New Postback Country Filtering Expands First-Party Data Control

Geo‑precise data sharing

Use Cases for Invoking Country Filters

Advertisers often launch marketing campaigns with multiple media partners that operate in different countries. Some advertisers may have varying data sharing rules with certain partners. For instance, an ad network operating exclusively in Japan should receive postbacks only for events occurring within Japan. Similarly, a different ad network could be active in all countries but restricted from receiving postback data for certain countries.

More real-world use cases for postback filtering by country:

• Regional exclusivity: An EMEA-only partner receives installs and in-app event postbacks from European countries, nowhere else.
• Global partner with exclusions: A worldwide network receives all events except for a handful of countries due to deal terms or performance.
• Privacy by design: Limit postback syndication in regions with stricter laws (e.g., GDPR, PIPA) to minimize data exposure and align with internal policies.
• Fraud mitigation: Exclude high-risk regions from postback syndication to keep downstream systems clean and partner relationships strong.

How to Set Up Country Filters for Your Postbacks

Setting up postback country filters is straightforward. The settings are managed at the individual media partner/ad network level for each of your apps.

1. Log in to Kochava.
2. Select the app you want to manage.
3. Navigate to Partner Configuration and find the desired media partner.
4. Expand the Postbacks section and select the postback you want to update.
5. Within the Edit Postback side drawer, locate Country Filters under the Data Sharing Controls section.
6. Pick Allow All or Allow Only and select the countries that match your policy.
7. Optionally, check “Apply country settings to all event postbacks” to enforce the same filtering rules across every event for the given media partner.
8. Once finished, click Save. Your postback syndication now respects your geo rules for that partner.
9. Repeat these steps for additional media partners or apps as necessary.

Please note that Country Filters are not available for Free App Analytics accounts. If you need to use this feature and would like to upgrade your plan, please contact support@kochava.com.

Postbacks: The Vital Feedback Loop

Postbacks play a vital role in your app marketing efforts. You can think of them as the always-on feedback loop between your app and your media partners. Whenever an install or in‑app event occurs, Kochava postbacks send timely, privacy‑safe signals that fuel key campaign performance functions:

• App event optimization (prioritizes users likely to complete valuable post-install actions)
• Suppression of already‑converted users (prevents wasted impressions and spend)
• Event hydration (populates retargeting and reengagement audiences with fresh event signals to keep messaging relevant)

Postbacks can also include attribution data, helping your growth partners understand which campaigns, placements, creatives, and keywords are driving the most conversions (e.g., app installs, in-app events, reengagements). The result is smarter bidding, cleaner audiences, and better return on ad spend.
