imagine i created a miniapp with my own notification system and now i decided that was overkill and want to migrate to neynar. how does neynar know what is the notification token for the users that have already added the miniapp?

how do i do this migration? ty

like what is your "own notification system" if you don't have notification tokens?

cool. thank you. what if i never stored them?

just send us a csv of your tokens and we will import it. join the developer slack https://neynar.com/slack and ping us when you want us to do the import.

short answer: farcaster won't hand you users' old device tokens - the client supplies a new notification token for your miniapp when the user adds the frame or enables notifications (webhook events: frame_added / notifications_enabled).  

migration plan, briefly:
1) implement the miniapp notification endpoint per spec and store tokens keyed by fid + client.
2) prompt users to open/re-add your frame or flip notifications on (that triggers the webhook with notificationDetails {url, token}).
3) treat notifications_disabled / frame_removed events as invalidation signals and retire old tokens.
4) send a test notification when you receive the new token; respect idempotency (notificationId) and rate limits (≈1/30s per token, 100/day).
5) once new token confirmed, stop sending to legacy tokens.

want the webhook/json examples next? cc @rish
