PWA Builder With Postbacks
A PWA builder with postbacks saves a buyer the thing that matters most — the gap between a conversion happening on the offer and the ad platform actually finding out about it. Without an S2S connection, the tracker and ad account only ever see clicks, not real traffic value. Here's what postbacks should cover out of the box, and how APEX handles it.
Why click-based postbacks aren't enough
Ad algorithms optimize toward whatever event they're fed: pass them a click, and delivery optimizes for clicks, not deposits or registrations. That setup quickly attracts traffic that clicks but doesn't pay — budget goes toward volume instead of audience quality. A postback tied to a real target event flips that logic back toward paying users.
What S2S actually means, versus a pixel
An S2S postback sends conversion data directly from the tracker's server to the ad platform's server, skipping the user's browser entirely — more reliable than a pixel, which gets blocked by ad blockers and some antidetect setups. That matters even more for a PWA, since offline mode and reinstalls can break a pixel's connection to the platform, while a server-to-server link doesn't depend on either.
What's often missing in off-the-shelf PWA builders
Not every niche builder lets you configure postbacks in the dashboard — some just hand over a static link that has to be wired into the tracker manually, leaving the integration work to the buyer. That adds a technical step and raises the risk of a misconfigured event parameter, especially when running several ad accounts side by side.
How postbacks work in APEX
In APEX, postbacks are configured right in the dashboard, with no code changes on the landing page, and support Keitaro and Facebook CAPI (among other systems) for sending conversions back to the ad account. A buyer picks which event to pass — install, registration, or deposit — and can run several campaigns with different postback setups at the same time.
FAQ
- How is an S2S postback better than a regular landing-page pixel?
- A pixel fires through the user's browser and can get blocked, while S2S goes directly from the tracker's server to the platform's server, so fewer events get lost and none of it depends on the user's device settings.
- Do I need development skills to set up postbacks in APEX?
- No — postbacks are configured in the dashboard by entering a URL and event parameters, with no code changes on the landing page.
- Which trackers does APEX support for postbacks?
- APEX supports Keitaro and Facebook CAPI along with other systems — check the dashboard for the current integration list when setting up a specific campaign.
