# Create a Transaction Plugin

The Transaction plugin stored in com.noknok.gateway.plugin.transaction.JWTTransactionManager is used in the API Server default configuration. A user-written custom transaction manager plugin must implement the ITransactionManager interface.

For information about building and deploying custom API Server plugins, see [Create a plugin](/dpoa/docs/s3suite94-create-a-custom-api-server-plugin).
