Only card transactions may be cancelled.

NOTE: When trying to cancel a transaction, the transaction should not be in final state.

Please follow the events for more info on transaction states.

Cancel the transaction with a POST request:

POST /v1/transaction/iSignthis-transaction-ID/cancel

Example: https://test.com/v1/transaction/256b4622-ea1d-4af0-8326/cancel

Once a transaction is successfully cancelled, a HTTP status code will be sent.
