+### Response actions
+
+The `response_actions` field in the endpoint configuration allows you to specify how to handle specific responses from the API based on status codes or content substrings. This is useful for handling edge cases like ignoring responses on specific conditions.

+This is an experimental feature and may change in future releases.

+
+#### Example
+
+```py
+{
+    "path": "issues",
+    "response_actions": [
+        {"status_code": 404, "action": "ignore"},
+        {"content": "Not found", "action": "ignore"},
+        {"status_code": 200, "content": "some text", "action": "ignore"},
+    ],
+}
+```
+
+In this example, the source will ignore responses with a status code of 404, responses with the content "Not found", and responses with a status code of 200 _and_ content "some text".
+
+**Fields:**
+
+- `status_code` (int, optional): The HTTP status code to match.
+- `content` (str, optional): A substring to search for in the response content.
+- `action` (str): The action to take when the condition is met. Currently supported actions:
+  - `ignore`: Ignore the response.
