# Disapprove Payout

The Disapprove Payout endpoint is used by the Merchant to explicitly disapprove a payout request before it is sent for processing. This step is required only when `autoMerchantApproval = 0`. Once disapproved, the payout transitions from a pending / queued state to expired state.

***

#### When to Use

Call this endpoint when:

* `autoMerchantApproval = 0`
* A payout has been created and is in a **pending / awaiting approval** state
* All required user inputs, KYC (where applicable), and validations are complete

***

#### Flow Context

1. Merchant creates a payout request
2. End user submits required details and completes KYC (if applicable)
3. Payout enters pending approval state
4. Merchant calls `disapprovePayout` (this endpoint)
5. Payout moves to Expired state

#### **Flow outcome:**

* The merchant disapproves the payout request
* The payout moves to **Expired** state
* The fiat disbursement does not start
* The merchant’s USDC balance remains unchanged
