To define the user actions, you can either pass the `actions` field as part of the JSON body (if you're
[publishing via JSON](#publish-as-json)), or use the `X-Actions` header (or any of its aliases: `Actions`, `Action`).

this. This format is much easier to write, but less powerful:

**Simple format syntax:**
Generally, the `X-Actions` header is formatted like this:
```
Actions: <action>, <label>, <params, ...>
```
or:
```
Actions: action=<action>, label=<label>, param1=..., param2=..., ...
```
An `action` is either [`view`](#open-websiteapp), [`broadcast`](#send-android-broadcast), or [`http`](#send-http-request),
and the `label` defines the button text. The other parameters depend on the action itself.
