Synara FAQ
How does Synara handle updates across different calendar providers?+
A single PATCH call updates the event everywhere, and Synara normalises provider-specific rules to avoid duplicates or ignored updates.
Do I need to change my existing event model?+
No, you can keep your current model and send events to Synara, which converts them to the ACE format and handles delivery.
What happens to legacy .ics files?+
Synara provides automatic .ics fallback for clients that only understand the old format.
Is there a limit on webhook calls?+
All plans include event webhooks; higher tiers get priority webhook queueing.
Can I test Synara before committing?+
All plans include a 30-day free trial, and there is a free tier for testing and prototypes.
