Transactions
Plan, launch, validate, and measure receipt-based challenges in OmniLab.
Transactions is OmniLab's receipt-challenge app. Use it when participants must upload or scan a receipt, prove they spent at the right merchant or above the right amount, and unlock rewards only after the receipt passes your acceptance and validation rules.
The articles below follow the real product flow: understand the model, build the receipt game, operate manual review when needed, then measure how the challenge performs.
Overview
Understand what a receipt challenge is and how the participant and operator flows fit together.
Get Started

Build
Configure appearance, acceptance rules, validation mode, challenge logic, and reward attribution.
Operate
Review sessions, check flagged receipts, and correct edge cases in the operator tool.
Launch
Test the participant journey, publish safely, and distribute the entry point.
Measure
Track submissions, validated spend, reward availability, and downstream transaction details.
Troubleshoot
Investigate acceptance failures, OCR issues, and suspicious repeat-submission patterns.
