+## Uploading Scripts via the API
+
+Script modules can be uploaded to NetBox via the REST API by sending a `multipart/form-data` POST request to `/api/extras/scripts/`. The caller must have the `extras.add_scriptmodule` and `core.add_managedfile` permissions.
+
+```no-highlight
+curl -X POST \
+-H "Authorization: Token $TOKEN" \
+-H "Accept: application/json; indent=4" \
+-F "upload_file=@/path/to/myscript.py" \
+http://netbox/api/extras/scripts/
+```
+
+Alternatively, a script module can be linked to an existing data source and data file instead of uploading a file directly:
+
+```no-highlight
+curl -X POST \
+-H "Authorization: Token $TOKEN" \
+-H "Content-Type: application/json" \
+-H "Accept: application/json; indent=4" \
+http://netbox/api/extras/scripts/ \
+--data '{"data_source": 1, "data_file": 42}'
+```
