On Spectrum Message (trigger)

Spectrum webhooks deliver inbound text messages. Attachments and other rich inbound types are coming soon.

When a message arrives, the trigger outputs:

  • $json.text - message body
  • $json.sender - who sent it
  • $json.phone - line that received the message (E.164)
  • $json.messageId, $json.platform, $json.spaceId

Line routing: Leave Line → Auto for trigger-to-reply flows. Choose Dedicated Line to filter or send from a specific number.

Filters: Line phone number, sender, space ID, DM vs group

Outbound numbers: Use E.164 format (+15551234567). Apple ID email routing for outbound is coming soon - contact daniel@photon.codes if you need it early.

Development

For local work on this package:

npm install
npm run build
npm run dev        # ngrok tunnel for webhook testing
npm run dev:local  # no tunnel (outbound actions only)

Local trigger testing requires ngrok. With npm run dev, activate the workflow or use Test this trigger, then text your line.
