# Repeat key

When creating a new run, you can pass a custom value that can then later be used to repeat the actions in a future run. This is especially useful when using it programmatically where consistency and expected behavior is important.

When a **repeatKey** is passed and the **intent, input/output schema** is exactly the same as the already existing action for that userId, then it will be a repeat run. A repeat run means that it will use the code used previously in a run to execute in a more consistent and reliable way.

### Using it

Set `repeatKey` field when creating a new run to a meaningful value to you**.** \
Recommendation: something that reflects the intent, e.g. `get_next_calendar_events` 

Other fields like `intent` , `context` , `selected integrations`  must still be set.
