# Getting Users Biological Age Acceleration

There are two ways to get biological age acceleration after it was calculated asynchronously (see [triggering-biological-age-acceleration-computations](https://developer.gerosense.ai/gerosense-api-reference/triggering-biological-age-acceleration-computations "mention")):

1. [Receiving results via a webhook](https://developer.gerosense.ai/gerosense-api-reference/getting-users-biological-age-acceleration/receiving-results-via-a-webhook) (preferred way).
2. [Receiving results via API polling](https://developer.gerosense.ai/gerosense-api-reference/getting-users-biological-age-acceleration/receiving-results-via-api-polling).
