### Update in Push API Ability to Pass Custom Value

1. Now developers can pass their own custom value while triggering API against each mobile number through **"reference\_number"** variable the data passed by you will be returned in the Event Webhooks i.e Delivery Reports
2. You can make use of this even when you are replying to a Webhook without calling API.
3. You can pass any value here like your internal message id etc and the same will be returned in the Event Webhook i.e Delivery Reports in the same variable name i.e **"reference\_number"** 
4. **Please note we don't check for duplicate or unique values here, we just return the value you passed**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.pickyassist.com/changelog/2021/may-2021.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
