  title: AB Tasty Decision Activate Flags API
  version: 2.0.0
  description: The AB Tasty Decision API is a server-side service that evaluates a visitors context against your active experiments, personalizations, and feature flags, then returns a deterministic decision which campaigns the user qualifies for, the selected variation, and any variables or content to render. It centralizes targeting, traffic allocation, and bucketing so you can power A/B tests, gradual rollouts, and personalized experiences from backends, mobile apps, or edge workers while keeping user exposure consistent. You pass identifiers and attributes at request time, use the response to render the experience, and pair it with event tracking for measurement...
