Signal
Not available yet
Reelwire does not post on Signal itself yet. Until it does, a channel on Signal is handed over by email or by webhook, and posted from there.
Why not yet
As of September 2026: Signal has no way for software to post at all: it is built for people messaging people, and offers apps no interface to send from.
Post meanwhile
Every channel on Signal can do what every channel could before the connectors:
- By email. Switch on Email under When a post is due, and a person posts from the post kit: Post a video by hand, Let your AI assistant post it or Post through a posting service.
- By webhook. Switch on Webhook, and a system of yours posts it, with nobody in between: Post through the platforms' APIs, Let an AI session post it or Post through a posting service's API.
Shapes
A channel on Signal renders 9x16, 4x5, 1x1 and 16x9, whichever you choose per channel. Its text is fitted to what Signal takes.
Ask for it
Need Signal sooner? Press Request Signal support in the channel's Platform connector section, or write to support@reelwire.io, with what you post there and how often, and we look at it with you.
