# Originate a loan

> Walk a loan application through its lifecycle — preview the schedule, submit, decide, and disburse — and see the loan account it produces.

Origination is the journey from "a borrower wants credit" to "a loan account exists and funds are out." Lender models it as an explicit application lifecycle so every decision is recorded and every disbursement is traceable.

## The application lifecycle

***

An application moves through named states. Each transition is a distinct operation, and each keeps a decision or disbursement record:

```
                approve ─────────► disburse
              ╱                              ╲
submit ──────┤                                └─► loan account
              ╲ reject
               ╲ withdraw
```

## Steps

***

<Steps>
  <Step title="Preview the schedule (optional)">
    `POST /api/v1/loan-applications/preview-schedule` computes the amortisation schedule for prospective terms **without originating anything**. Use it to show installments and disclosures before anyone commits.
  </Step>

  <Step title="Submit the application">
    `POST /api/v1/loan-applications` creates the application against an active product version. Writes are idempotent — send an idempotency key and a retried submit collapses to the same application.
  </Step>

  <Step title="Decide">
    Resolve the application with exactly one of:

    * `POST /api/v1/loan-applications/{id}/approve` — accept it; a decision record is kept.
    * `POST /api/v1/loan-applications/{id}/reject` — decline it, with a decision record.
    * `POST /api/v1/loan-applications/{id}/withdraw` — retract it before it is decided.
  </Step>

  <Step title="Disburse">
    `POST /api/v1/loan-applications/{id}/disburse` releases funds. Lender records the disbursement facts, books the disbursement to the ledger through the product's accounting profile, and the loan becomes an active **loan account** you service from here on.
  </Step>
</Steps>

## What you get

***

Disbursement produces a **loan account** — the servicing view of the live contract, carrying its schedule, transactions, charges, and audit history. Continue in [Service a loan](/en/lender/service-a-loan).

## What happens downstream

***

The lifecycle emits `loan_application.submitted`, `loan_application.approved`, `loan_application.rejected`, `loan_application.withdrawn`, and `loan_application.disbursed`. The disbursement also drives a ledger posting via the [posting path](/en/lender/lender-in-the-platform).

<Info>
  Brazilian origination adds regulated steps — CET disclosure and capitalization consent — covered in the [Brazil regulatory pack](/en/lender/brazil-regulatory-pack). The payroll-deducted **consignado** flow originates in a single call; see [Consignado privado](/en/lender/consignado-privado).
