Looking for a Free Ticketing System with API for My React Platform

Have you considered using a service like OS-Ticket? It's a solid option, and it can make your notification process easier, especially if you set up webhooks. You can integrate it for notifications on platforms like Discord or Fluxer with a bot. You might also want to clarify how you’d like to receive notifications—like through push notifications or email? That could really help narrow down the best option for your project!

Zammad might be another option for you. It can handle conversations through their API, allowing you to create tickets easily and manage them all through your React app. It seems to fit your needs without too much hassle!

Check out Featurebase! It allows you to create and manage tickets via its API, which seems to fit what you're describing perfectly. You can simply have your React form send a POST request to Featurebase, and it'll manage everything in your support inbox. Plus, they have an embeddable messenger widget if you ever decide to switch from your own form.

If you're okay with a paid option in the future, Deskpro is worth looking into. Their API lets you create tickets and send notifications in various ways. It might not be free, but the API functionality is solid and could save you time in the long run.
