The Checkout SDK integrations are being phased out
This means we are:
  • No longer developing the Checkout SDK.
  • Not accepting new Checkout SDK integrations.
We strongly recommend you switch to the latest online payments integration. We will announce the end-of-life plan in 2022. From the moment we announce the end-of-life plan, you will have approximately 12 months to migrate.
