# Migration v45

Breaking change: when calling `createSubscription`, the paymentOptions object now expects a `sendConfirmationEmail` boolean. 
The Subscription API defaults to `true` if the value is absent, but as part of Subscriber Growth short-term pass experiment, we need to supress sending out the email


## What do you need to do
`next-subscribe` will have a PR that ingests this change. Other repos need to make sure that the `options` object passed to `createSubscription` has a key `sendConfirmationEmail` with appropriate value.
