Update a Checkout Flow to Handle Promotions

If you created a custom checkout flow before Winter ’22, it didn’t include support for promotions. You can update your existing flow to make it capable of handling promotions.

This section assumes that your existing checkout flow is based on the legacy checkout flow template. In previous releases, this flow was the most frequently used checkout flow. The legacy B2B checkout flow template does not support tokenization for credit card payments with external providers.
