Welcome to the forum @vijayaprabu

You are going to have to give us a lot more information than that before we can give you any sensible suggestions.

Hi @jbudd

i have a client which request a data on request. in the request its mentioned that in what interval the data has to be sent till the request is revoked. i have seen the [Trigger a flow at regular intervals : Node-RED](https://cookbook.nodered.org/basic/trigger-at-interval) and [Route or block a message based on a context value : Node-RED](https://cookbook.nodered.org/basic/route-on-context). what i am looking is like set the interval based on the context from the request

Try the cron-plus contrib node.

You can use the request to specify or cancel a schedule of times to inject data to the flow.

A possibly simpler way is to use a Change node to move the required interval (in milliseconds) into `msg.delay` then feed that into a Trigger node configured like this

That will pass the message on and then send it again at the interval specified in `msg.delay`. The 10 seconds specified is ignored because `override delay` is ticked.  
When you get the revoke instruction then then send the Trigger node a message containing just `msg.reset` set to `true` and it will stop sending.
