Limitations

TLDR: Due to technical limitations, reminders cannot be sent via WhatsApp. Read on for more details.

WhatsApp's API has restrictions that prevent us from sending ad-hoc messages unless you have interacted with Hyperaide on WhatsApp within the last 24 hours. Although this interaction window allows us to send some reminders, it’s not a reliable method to ensure delivery.

WhatsApp does permit the use of predefined templates for messages. We could utilise this feature to send basic reminders, like:

Reminder ‼️
Return book to library

However we feel personalised messaging is essential to our user experience, and using a generic template deviates from this standard. We may reconsider this approach in the future.
