Using the JavaScript API with content security policies

If you apply content security policies (CSP) to your resources, for your JavaScript implementation to work, you need to allowlist the AWS WAF apex domain awswaf.com. The JavaScript SDKs make calls to different AWS WAF endpoints, so allowlisting this domain provides the permissions that the SDKs need to operate.

The following shows an example configuration to allowlist the AWS WAF apex domain:

connect-src 'self' https://*.awswaf.com;
script-src 'self' https://*.awswaf.com;
script-src-elem 'self' https://*.awswaf.com;
