Sending Messages Outside the 24-Hour Messaging WindowRegular 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
