# Void an APM transaction

`POST /apm/v3/void`

Voids a transaction run using an Alternative Payment Method.

If you do not know the `paymentId` or `amount` to use, make a call with the [View transactions](https://docs.nexiopay.com/reference/viewtransactions) endpoint with the query filter of `transactionStatus=10` and `plugin=` to get an array of possible transactions that have authorized but are not yet settled.

For more help with this endpoint, see the [Void an APM transaction](https://docs.nexiopay.com/docs/void-an-apm-transaction) tutorial in Guides.
