I have created a local setup of openmrs enterprise v 2.3.2 I have created a new table in openmrs db, and want to retrive all data on basis of uuid by an REST API. I want to create a new controller and service that will use session factory and retrieve data using sql native query. How can I achieve this? Thanks in advance ---

@narukumar You can follow this [link](https://wiki.openmrs.org/display/docs/Adding+a+Web+Service+Step+by+Step+Guide+for+Module+Developers). You can easily setup a new REST endpoint with the help of webservices.rest module. ---

Thank you @medhavi for you help. I have created on module and created an endpoint, but I am not able to call that endpoint from any client and getting [resource not found](https://pastebin.com/XnDHTrGM) . Can you tell me what is the entry endpoint for openmrs and what is the entire API flow in openmrs. Looking forward to hearing from you. ---

@narukumar please ensure that you are calling the correct endpoint as you mapped inside `RequestMapping` > @RequestMapping` `(` `“/rest/”` `+ RestConstants.VERSION\_1 + ` `“/yourmoduleid”` `) ---
