Adds integration identifier parameter to Checkout Sessions
What’s new
You can now use the integration_identifier parameter when you create a Checkout Session. This parameter accepts a string of up to 200 characters that can include alphanumeric characters, dashes, underscores and periods.
Impact
You can now group and track your Checkout Sessions using integration identifiers, helping you analyse performance across different parts of your application or different integration patterns. This is particularly useful if you use multiple checkout flows or want to track conversions from different sources.
The integration_identifier parameter is optional, so existing integrations continue to work without any changes.
Changes
