Linear
Trigger Wexio flows from Linear issue events
Linear signs webhook bodies with HMAC-SHA256 in Linear-Signature (hex, no prefix). Wexio's Linear preset under Generic HMAC-SHA256 handles this.
Provider docs: Setting up webhooks in Linear
Setup
1. Wexio connection
New connection → Inbound → Linear preset.
2. Linear webhook
In Linear → Settings → API → Webhooks → New webhook. Paste the Wexio URL, pick the events. Linear shows a signing secret you copy into Wexio's Signing secret field.
3. Contact resolution
Linear events usually don't carry end-user identifiers. Route to a static ops contact.
4. Capture schema, bind a flow
Standard flow. Branch on {{webhook.action}} for issue lifecycle (create, update, remove).
Troubleshooting
| Symptom | Fix |
|---|---|
| Signature mismatch | Re-copy the signing secret from Linear |
| Missing events | Check the webhook's event subscriptions in Linear |
