Use the Request Size Limit policy to restrict requests based on the size of their content.
The Request Size Limit policy executes early in request processing to limit the effects of oversized requests.
Expression Enabled Fields in API Policies
All expression enabled fields take expressions from the SnapLogic Expression Language and the API Policy Manager functions.
When this policy should be applied
If the request has content (for example, a POST or PUT request) and the content length is missing or is larger than the configured limit, the request is rejected.
