Why this helps
Choosing a channel for a push-enabled workflow is harder when you cannot quickly see which channels have subscribed devices.
- Find channels with at least one subscribed device.
- Reduce guesswork when reviewing possible push notification destinations.
Setup
Build it in a few focused steps.
- 1Connect Airtop and Ably once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis in plain language from any channel.
- 3In one instruction, ask Notis to list Ably channels with push subscriptions and summarize channels relevant to your Airtop workflow.
- 4Choose a webhook trigger and select where run reports should go.
- 5Test with one real discovery request and review the returned channels.
