requestParameters property
For WebSocket APIs, a key-value map specifying request parameters that are passed from the method request to the backend. The key is an integration request parameter name and the associated value is a method request parameter value or static value that must be enclosed within single quotes and pre-encoded as required by the backend. The method request parameter value must match the pattern of method.request.. , where is querystring, path, or header; and must be a valid and unique method request parameter name.
For HTTP API integrations with a specified integrationSubtype, request parameters are a key-value map specifying parameters that are passed to AWS_PROXY integrations. You can provide static values, or map request data, stage variables, or context variables that are evaluated at runtime. To learn more, see Working with AWS service integrations for HTTP APIs.
For HTTP API itegrations, without a specified integrationSubtype request parameters are a key-value map specifying how to transform HTTP requests before sending them to backend integrations. The key should follow the pattern <action>:<header|querystring|path>.<location>. The action can be append, overwrite or remove. For values, you can provide static values, or map request data, stage variables, or context variables that are evaluated at runtime. To learn more, see Transforming API requests and responses.
