Question 1

What events can Relay send to my tools?

Accepted Answer

Call completed, call missed, text received, text sent, voicemail received, transcription ready. Each event fires in real time to the URLs you configure — up to 5 per workspace.

Question 2

Does it work with Zapier, Make or n8n?

Accepted Answer

Yes — their “webhook” triggers receive Relay events directly. From there, push to your CRM, spreadsheet or 1,000+ connected apps.

Question 3

Are the webhooks secure?

Accepted Answer

Every delivery is signed (HMAC SHA-256) with an anti-replay timestamp. Your system verifies the signature and knows the event really came from Relay. The secret is shown only once, at creation.

Question 4

What if my endpoint is temporarily down?

Accepted Answer

Relay retries once, and delivery is never blocking: your calls and texts keep working normally, broken webhook or not.
