Request Filter

A Filter is a function that receives the request and the response object from express and must return a boolean value to inform if the given request should target the destination API or if it should be ignored.

Each filter must be defined on its own .js file.

Example:

/**
 * Where request and response are the original request and response objects created by [express](http://expressjs.com)
 */
module.exports = function (request, response) {
  return true;
};

You can configure a request filter middleware:

• Admin Rest API: POST /midleware/filters
• SDK: sdk.middleware.addFilter(name, fileName);
• CLI: treeGatewayConfig middleware filter -a <name> ./filename.js
