How Offerwalls Work: Technical Deep Dive for Developers
A technical walkthrough of the offerwall lifecycle from SDK initialization to reward delivery.
1. SDK Initialization
When your app launches, the RewardingHub SDK initializes with your App ID and API Key. It establishes a secure connection, caches offer data, and registers the device for attribution.
2. Offer Loading
When a user opens the offerwall, the SDK requests offers from our server. The response is filtered by device type, OS version, geo, and user history. Offers are ranked by expected revenue (eCPM optimization).
3. Completion Tracking
When a user completes an offer, the advertiser's server notifies RewardingHub via postback. We validate the conversion against our fraud detection layers.
4. Reward Delivery
After validation, we send a server-to-server postback to your server with the reward amount. Your server credits the user's account. Read the full SDK documentation.
