Signatures

Prove it came from Embers. Reject what did not.

Every request carries webhook-id, webhook-timestamp, and webhook-signature. Sign the id, the timestamp, and the raw body with your secret and compare. A changed body never matches.

HMAC-SHA256, the Standard Webhooks scheme
webhook-id is stable, so you can deduplicate
Join on linkedin_urn, not the profile URL

Retries and pauses

Down for a day? The lead still arrives.

A failed delivery is retried seven times, from 30 seconds to 5 days apart. A non-retryable error like a 404 pauses the endpoint at once, and events wait as blocked instead of being dropped.

Eight attempts over about 6.3 days
Editing a paused endpoint's URL clears the pause
Replay failed and blocked deliveries from the log

Recipes

No native Zapier app needed. One webhook feeds them all.

Zapier, Make, Clay, and n8n each catch an Embers webhook. Register their URL as an endpoint, send a sample so they learn the shape, and build the rest where you already work.
