# Request Collateral

This endpoint initiates a request for the borrower to transfer the required collateral associated with a loan. It is typically triggered once the underwriting process is successfully completed and the loan has been approved.

**What it does:**

* Signals the borrower to deposit collateral assets
* Links the collateral to the corresponding loan
* Updates the loan status to reflect pending collateral transfer

**When to use it:**

* After underwriting approval and risk assessment
* Before disbursing the loan amount
* To ensure adequate security is received for the loan

## Request Body

The request body must include the unique identifier of the loan for which collateral is being requested:

```json theme={null}
{
  "loanId": "0x5a0c0663a48e3abf16c7f0ee632b57da833e44e02a290fc0920ea2858da31f73"
}
```
