Opinionated setup path
- 1. Create or choose an environment and copy the key type that matches your runtime: server, mobile, or client.
- 2. Add a default value for every flag you read in code so failures degrade safely.
- 3. Pass a stable context identifier whenever your rollout depends on user, account, or service targeting.
- 4. Return to the API reference or webhook reference when you need exact request shapes.
Next step
Take the next integration step in your own stack.
Start with the quickstart that matches your runtime, then return to the reference pages when you need exact request and payload details.
