+## Making API Calls from Within a Report Template
+
+If you plan to make API calls (e.g., using axios or fetch) from within a report template, you need to configure additional settings to ensure proper functionality:
+
+Append the following code to `/rmm/api/tacticalrmm/tacticalrmm/local_settings.py`:
+
+```python
+from corsheaders.defaults import default_headers
+
+CORS_ALLOW_HEADERS = (
+  *default_headers,
+  "x-api-key",
+)
+```
+
+Then restart the rmm service:
+
+```bash
+sudo systemctl restart rmm
+```
