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:
