# Cancels a payment session

<a id="flute-v2-post-payment-sessions-paymentSessionId-cancel"></a>
<span class="api-endpoint">POST {{<a href="#urlbases">baseURL</a>}}/v2/payment-sessions/{{paymentSessionId}}/cancel</span>
This endpoint cancels a payment session.
A payment session can only be canceled successfully if:
* The payment session must belong to the requesting merchant.
The `merchantId` from the API token must match the session's merchant.
It returns 403 Forbidden if it does not.
* The session is in `Created` status.
Any other status, such as `Completed`, `Failed`, or `Cancelled`, fails with the validation error: "Payment Session can be canceled only in Created status".
