It occurs to me that this might be not overly hard. An XC that picks up a webhook. And returns a value. Feasible? Already been done?

Hola Mark!

Do you mean a Yes-Code (YC)? … If so, I think so!.

Maybe a webhook or making an HTTP request to process its reply can be carried out:

```auto
const data = await fetch("YOUR_URL")
const json = await data.json();
return json.{Param1} + " / " + json.{Param2} + " / " + json.{Param3} 

```

Saludos

Sorry if this is a wrong question to ask but does it trigger when data is passed to the webhook or are we sending calls every X seconds to the webhook to ask if it has new data? Is there a chance of new data being missed if we don’t call at the right time? Thank you 😄

Hola Thinh

If I understood well your question 😆, I’d say the code showed above does:

1- makes an http request  
2- waits for its reply  
3- retrieves the entire JSON data  
4- returns your wished values

In theory, this should be done every time you run the code manually but if you create a way to fire it based on time (using Math and Now), you might have your data updated periodically.
