# Apple Messages for Business

This section covers the different rich templates you can create and use on Apple Messages for Business

### Image size guide

When creating interactive messages when selecting the style options use the following images sizes for the best formatting:

* **Icon**: 40 x 40 points at @3x scale (120 x 120 pixels)
* **Small**: 60 x 60 points at @3x scale (180 x 180 pixels)
* **Large**: 263 x 150 points at @3x scale (789 x 450 pixels)

Received messages should use the Large icon style and Reply messages should use the icon style.

For list picker images these should be:

* **180px × 180px** (60pt × 60pt @3x resolution).

{% hint style="info" %}
Apple requires all images in interactive messages and rich link previews to be PNG, with a maximum binary size of 200 KB per image. Bird converts your images to PNG and downscales oversized ones automatically — note that animated GIFs become static images. Regular image and file attachments are not affected.
{% endhint %}

### Text limits

Any text rendered in the Messages app UI — titles, subtitles, labels, hint text, and button text — is limited by Apple to 200 characters. Longer values are truncated before sending, so keep UI text concise.

## 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://docs.bird.com/applications/content/message-templates/how-to/apple-messages-for-business.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.
