Overview

Set up Datadog Feature Flags for your applications. Follow the platform-specific guides below to integrate feature flags into your application and start collecting feature flag data:

Context attribute requirements

Evaluation context attributes must be flat primitive values (strings, numbers, booleans). Nested objects and arrays are not supported and will cause exposure events to be silently dropped.

Use flat attributes in your evaluation context:

const evaluationContext = {
  targetingKey: 'user-123',
  userId: 'user-123',
  tier: 'premium',
  age: 25
};

await OpenFeature.setProviderAndWait(provider, evaluationContext);

Avoid nested objects and arrays:

// These attributes will cause exposure events to be dropped
const evaluationContext = {
  targetingKey: 'user-123',
  user: { id: 'user-123' },        // nested object - NOT SUPPORTED
  features: ['beta', 'analytics']  // array - NOT SUPPORTED
};
