# Certificate validation

<p>Chromium validates website TLS certificates by default. Uploaded custom certificate authorities and certificate CRUD endpoints are not available in the native browser API.</p>
<p>A supported transport may accept <code>browserSettings.ignoreCertificateErrors:true</code> at creation for a deliberate controlled test. That changes website certificate checks inside that session; it does not change Tooluse.net API TLS validation or install a trusted authority. Prefer valid certificates for normal browsing.</p>
<p>See <a href="/browsers/getting-started/create-browser-session">Create a browser session</a> and the <a href="/browsers/api">Browsers API</a> for authentication, request fields, and limits.</p>
