Hi seoseo.

User ID is included in the common property in webhook event object. https://developers.line.biz/en/reference/messaging-api/#common-properties

like this

  "source": {
    "type": "user",
    "userId": "U4af4980629..."
  }

So you can get User ID at every webhook.

if you can not do that, please let me know more details.
