**My Usecase:**

I just need to check one API response code 200 for every one minute. If connection lost need to trigger a pop up view.

**Things I tired:**  
1.Tired using the system.net.httpget() , if response is None , it will trigger a popup. But not working .  
2. Tired to execute velow scripts , but if response cut throwing error, I know its a simple one, but not able to achieve , Kindly help me on this !

```python
client = system.net.httpClient()
		response = client.get("http://192.168.43.75:5000/data")
		if response.statusCode == 200:
			system.perspective.openPopup("testing", "popup1")
		else:
			system.util.getLogger("FlaskCheck").info("Received response but status not OK")

```

Where is this script placed?  
Scripts like this should be in gateway scheduled scripts, then use a message handler to message the failure out of the gateway scope into the perspective session, where the `system.perspective.* `script will actually work.

Hey David, As instructed I have been placed the code in Gateway scheduled event. But somehow it is not working again. please guide me

```python
		
		client = system.net.httpClient()
		response = client.get("http://192.168.0.101:5000/data")
		if response.statusCode == 200:
		
# Sends a message to all Message Handlers configured on the current view, indicating that a new item has been added to a list.
			system.perspective.sendMessage("NewItem", scope = "session",sessionId="6a181fdd-5c61-49de-8b5b-a49679447839")
		else:
			system.util.getLogger("FlaskCheck").info("Received response but status not OK")

```

My message handler was placed in one view's root container, there just need to open the popup.

Unless that is there for show, you have hard-coded the sessionId in your call to send a message.

> [@srinivasan\_s](#):

You are also using a `system.perspective.sendMessage` in a scheduled event when you should be using `system.util.sendMessage`. There is a difference, they are not interchangable. You also need a session message handler, to capture the message from `util.sendMessage` and then call `perspective.sendMessage`.

> **[system.perspective.sendMessage | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-perspective/system-perspective-sendMessage)**
>
> Send a message to a message handler within the same session.

> **[system.util.sendMessage | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-util/system-util-sendMessage)**
>
> This function sends a message to clients running under the Gateway, or to a project within the Gateway itself.
