Signal + Foldr Integration
Signal is the gold-standard encrypted messenger. Signal has no first-party bot API, but `signal-cli` + Foldr lets you build a relay that uploads forwarded attachments to Foldr and replies with a short link.
How to Connect Signal to Foldr
Create an inbound webhook in Signal
In Signal's webhook / automation settings, add a new webhook that fires on the event you care about.
Point the webhook at Foldr
Use https://foldr.space/api/v1/webhooks/ingest?token=<your-foldr-webhook-token> — Foldr accepts JSON bodies and deduplicates by source ID.
Add an outgoing Foldr webhook (optional)
If you want events to flow the other way (Foldr → Signal), add your Signal webhook URL to your Foldr workspace settings.
Common Use Cases
- Drop a Foldr short link into Signal whenever a file is ready
- Receive Signal notifications when a Foldr upload finishes
- Use Foldr as the file host when Signal's native attachments are too limited
- Let Signal bots respond to mentions with a Foldr URL
Signal + Foldr FAQ
How do I connect Foldr to Signal?
You connect Foldr to Signal via Webhook. Full steps are listed above under "How to Connect". In short: create a Foldr API key, configure the Webhook integration pointed at https://foldr.space/api/v1/, and map Signal's data into Foldr's request body.
Do I need a paid Foldr plan to use Signal with Foldr?
The Foldr free tier supports basic uploads via the API with 7-day expiry. For integration use with Signal — higher rate limits, permanent storage, multiple API keys, and webhook subscriptions — Foldr Pro (from $5/mo) is recommended.
What Foldr features can I call from Signal?
From Signal you can invoke any Foldr action: uploading files (up to 2 GB each), creating short links, generating bio pages, creating hosted forms, and reading download analytics. See the Foldr API docs for the full endpoint list.
Is there an official Foldr app for Signal?
Not a first-party app — Foldr integrates with Signal through Webhook, which is usually a better fit because it doesn't require installing an extra app. If you'd rather have a native integration, let us know at foldr.space/contact.
