# Write Log Message

{% hint style="info" %}
**Block Information**

Available in: Page Flow and Cloud Flow

Toolbox Category: Action - Log

Block Type: [Regular](/app-editor/page-flow/block-anatomy.md#regular-block)
{% endhint %}

The **`Write Log Message`** block is available in [Page Flow](/app-editor/page-flow.md) and [Cloud Flow](/app-editor/cloud-flow.md) and operates in similar ways with some minor differences.

In Page Flow this block allows you to write messages into the browser's [web console](https://developer.chrome.com/docs/devtools/console/) log, whereas in Cloud Flow it writes a message into the Zingy's cloud logs, which can be accessed from the Cloud Flow tab in the [App Editor](/app-editor/app-editor-tour.md).

The block consists of the following:

* *Message:* a [Value Parameter](/app-editor/page-flow/block-anatomy.md#value-parameters) that accepts a [*text*](/app-editor/page-flow/references/value-types.md) value for the message you want to log.
* *Category:* a [Value Parameter](/app-editor/page-flow/block-anatomy.md#value-parameters) that accepts a [*text*](/app-editor/page-flow/references/value-types.md) value that specifies the category of the message. This is useful for filtering out messages when conducting a post-mortem or [debugging](https://en.wikipedia.org/wiki/Debugging).
* *Level:* a [Value Parameter](/app-editor/page-flow/block-anatomy.md#value-parameters) that accepts a [*numeric*](/app-editor/page-flow/references/value-types.md) value  specifying the severity level of the message. This is only supported in Cloud Flow and is useful for further filtering out messages when conducting a post-mortem or [debugging](https://en.wikipedia.org/wiki/Debugging).

## Usage Example

The example below shows the Write Log Message block used when the a button is clicked. The message "The button was clicked" is written to the log.

<div align="left"><figure><img src="/files/zTPHT4oGZScxQyuiImCH" alt="" width="563"><figcaption><p>Example of Write Log Message block</p></figcaption></figure></div>

For the *Category* [value parameter](/app-editor/page-flow/block-anatomy.md#value-parameters), we use the [Log Category](/app-editor/page-flow/toolbox-blocks/log-category.md) block with the *INFO* category selected.&#x20;

{% hint style="success" %}
Note: You can provide your own categories and do not have to use the [Log Category](/app-editor/page-flow/toolbox-blocks/log-category.md) block.
{% endhint %}

This would produce a message similar to the one below:

```log
[LOG(info) 08/09/2023 16:49:01.760] The button was clicked
```
