<action1>, <label1>, paramN=... [; <action2>, <label2>, ...]
|

```
|
||||
|
||||
The `action=` and `label=` prefix are optional in all actions, and the `url=` prefix is optional in the `view` and `http` action.
|
||||
The format has **some limitations**: You cannot use `,` or `;` in any of the values, and depending on your language/library, UTF-8
|
||||
characters may not work. Use the [JSON array format](#using-a-json-array) instead to overcome these limitations.
|
||||
Multiple actions are separated by a semicolon (`;`), and key/value pairs are separated by commas (`,`). Values may be
|
||||
quoted with double quotes (`"`) or single quotes (`'`) if the value itself contains commas or semicolons.
|
||||
|
||||
The `action=` and `label=` prefix are optional in all actions, and the `url=` prefix is optional in the `view` and
|
||||
`http` action. The only limitation of this format is that depending on your language/library, UTF-8 characters may not
|
||||
work. If they don't, use the [JSON array format](#using-a-json-array) instead.
|
||||
|
||||
As an example, here's how you can create the above notification using this format. Refer to the [`view` action](#open-websiteapp) and

[`http` action](#send-http-request) section for details on the specific actions:
