## API Considerations

When using the Ayrshare API:

* Posts exceeding character limits will be rejected with an error
* Some platforms may truncate content rather than reject it (Telegram, Snapchat Spotlight)
* Consider using `shortenLinks: true` for platforms with tight limits

## Updates and Changes

Social media platforms do update their character limits. This guide is current as of the last update, but we recommend:

* Using our API error responses to identify limit issues
* Checking the Ayrshare [Latest Updates page](/whatsnew/latest) for platform updates
