+A [service account](https://developer.mixpanel.com/reference/service-accounts) is necessary to authenticate Warehouse Connectors API requests. Once you have created a service account and obtained your user name and secret, you can make a request to trigger a warehouse import.
+
+```bash cURL Basic Auth
+curl -X PUT https://mixpanel.com/api/app/projects/<your_project_id>/warehouse-sources/imports/<your_import_id>/manual-sync \
+	--user "<serviceaccount_username>:<serviceaccount_secret>"
+```
+```shell cURL Header
+curl -X PUT https://mixpanel.com/api/app/projects/<your_project_id>/warehouse-sources/imports/<your_import_id>/manual-sync \
+	--header 'authorization: Basic <serviceaccount_username>:<serviceaccount_secret>'
+```
+```python Python Requests
+import requests
+requests.put(
+  'https://mixpanel.com/api/app/projects/<your_project_id>/warehouse-sources/imports/',
+  auth=('<serviceaccount_username>', '<serviceaccount_secret>'),
+)
+```
