❗️

Sending Messages Outside the 24-Hour Messaging Window

Regular text messages and media messages (i.e., any non-template messages) can only be delivered within 24 hours of the customer's last message to your business.

If the business sends a message outside this 24-hour window, an error will be returned by the API.

Message templates are not subject to this restriction and should be used for reaching customers outside the 24-hour window.

Best Practices

• Keep audio files under 16 MB for reliable delivery
• Use compressed formats like AAC or MP3 for smaller file sizes
• Ensure audio URLs are publicly accessible before sending
• AMR format is optimized for voice recordings
• Audio messages do not support captions or filenames

🚧

Limitations

• Captions are not supported for audio messages
• Filenames cannot be specified for audio files
