Hi @akshay_shukla,
Please confirm if "Apache Sling Referrer Filter" is configured like below:
- Enable allow empty
- Remove the POST method from filters
In OSGI configurations (http://localhost:4502/system/console/configMgr), locate “Apache Sling Referrer Filter”. Enable the allow empty property, and remove the post method from filters property.
Secondly, in OSGI configurations (http://localhost:4502/system/console/configMgr), locate “Adobe Granite CSRF Filter”. Remove the post method from filters property.
After making configurations to the two OSGI configurations, you should be able to make a POST request from your HTTP REST Client to your AEM instance.
Thanks!!
