Mini Apps

easiest way to build on farcaster @ neynar.com | /neynar

Is there any API to detect if a user has installed a given mini app? 

Not when they’re inside of the app itself, but to know whether or not they’d be able to receive a mini app notification

@neynar not sure if this is anywhere in the API or on the upcoming feature list 😬

good use case. if you're using the neynar webhook url in your mini app manifest, there is a way to know if you have an enabled notification token for user B.

You use this API and pass in the fids as a filter parameter https://docs.neynar.com/reference/fetch-notification-tokens

App installed is a requirement before notifications can be enabled, so you can parse the response and take next steps accordingly

you guys are, once again, legends. thank you

Just to be more explicit:

User A has added the app and wants to invite User B to play a game.

User B hasn’t added the mini app so they won’t receive notifications.

In this scenario, I’d like to be able to detect B’s lack of installation and instead go with a cast/DM as the method of notifying
