  x-extensions-note: "This API uses the `x-expression` vendor extension to indicate that a string property is a DSL expression.\nSupported types:\n\n\n  - `boolean`: An expression evaluates to boolean. For example, `context.topic.name == 'my-topic'`\n  - `string`: A template string expression that evaluates to a string or a literal string value. For example,\n    `${context.topic.name.substring(0, context.topic.name.length-4)}` or `my-literal-value`\n\nAdditionally, `x-sensitive` flag indicates that a field contains sensitive information. When the value\nof the field is provided in plain text, it's encrypted at rest and it's never returned in API responses.\nWhen the value is an expression, the expression itself is stored and returned in API responses.\n\n`x-min-runtime-version` indicates the minimum Event Gateway runtime version required to use a certain policy or\npolicy feature. The runtime version can be configured at the Event Gateway entity level. It must be a string\ncontaining a semantic version in the `MAJOR.MINOR` format, e.g., `\"1.1\"`.\n"

        Integration workflow:

        1. The billing system creates invoices and transitions them through lifecycle states (draft → issuing → issued)

        2. The integration receives webhook notifications about invoice state changes

        3. The integration calls back to provide external system IDs and metadata

        4. The integration reports payment events back via the payment status API


        State synchronization is controlled by hooks that pause invoice progression until the

        external system confirms synchronization via API callbacks.'
