# Loan data

Layer models loans as first-class financial events. Each loan has a dedicated ledger account, one or more **proceeds** (the funds or assets received when the loan is drawn), and **payments** split into principal, interest, and fee portions. See the [Loan object](/api-reference/loan/loan) for the full data model and the [loan endpoints](/api-reference/v1/loans/create-loan) for the API.

Every loan has a `loan_type`. Follow the guide for the type you're importing:

| Loan type                                                      | `loan_type`           |
