What is the "meta" field returned in a /transactions request?

When making a /transactions request, you will see there's a 'meta' field. For example:

 "meta": {
      "transaction_type": "Debit",
      "provider_id": "19564dab-aef6-4cb2-b66b-c9aeb8388eeb",
      "provider_merchant_name": "Lamb Flag",
      "provider_category": "CARD_PAYMENT"
      "user_comments": "this is a transaction"

}

This field is optional and we will display it exactly as it comes from the provider. It will most likely differ from bank to bank, depending on how they have decided to implement it.
