# ActiveContext


Contains information about the contexts that a user is using in a session. You can configure Amazon Lex V2 to set a context when an intent is fulfilled, or you can set a context using the [PutSession](API_runtime_PutSession.md), [RecognizeText](API_runtime_RecognizeText.md), or [RecognizeUtterance](API_runtime_RecognizeUtterance.md) operations.

Use a context to indicate to Amazon Lex V2 intents that should be used as follow-up intents. For example, if the active context is `order-fulfilled`, only intents that have `order-fulfilled` configured as a trigger are considered for follow up.
