# Network Security Config
Codavel SDK requires HTTP traffic to be sent to the Codavel interceptor service. In order to allow this traffic, your app may need a specific configuration.
Notice: if your app currently does not set a network security config, this step is not necessary
Open your app's manifest and look for the network security config in you application tag:
In this case, the file with the configuration is network_security_config.xml, located in the res/xml folder.
Open it, and add the following lines (adapt it if necessary):
(...) <domain-config cleartextTrafficPermitted="true"> <domain includeSubdomains="true">127.0.0.1</domain> </domain-config> (...)
With this configuration, you are allowing HTTP traffic to be sent to Codavel SDK interceptor service running on the localhost.
