XML XSD Validator

Use the XML Validator policy to validate a request against an XML Schema Definition (XSD). You can upload an XML XSD file in the policy dialog as a valid Swagger XML document. If an invalid path or parameter or object is not defined in the schema, the client receives a Schema Validation Failed error.

Alternatively, you can use the specification that you upload to create an API.

Policy Execution Order

This XML Validator policy executes after the request has been authenticated. You can use both the XML XSD and XML DTD policies concurrently as long as the schema definitions do not conflict.


Expression Enabled Fields in API Policies

All expression enabled fields take expressions from the SnapLogic Expression Language and the API Policy Manager functions.

Edit XSD
