+### Ignoring certain HTTP endpoints
+
+You might have endpoints you don't want requests to be traced, perhaps due to the volume of calls or sensitive URLs.
+
+You can use `ignore_endpoint` method with the hostname and/or URLs you'd like it to be ignored - globs (`*`) are allowed.
+
+```python title="Ignoring certain HTTP endpoints from being traced"
+from aws_lambda_powertools import Tracer
+
+tracer = Tracer()
+# ignore all calls to `ec2.amazon.com`
+tracer.ignore_endpoint(hostname="ec2.amazon.com")
+# ignore calls to `*.sensitive.com/password` and  `*.sensitive.com/credit-card`
+tracer.ignore_endpoint(hostname="*.sensitive.com", urls=["/password", "/credit-card"])
+

+def handler(event, context):
