Why Bubblehook

Signature verification

We validate Fizzy HMAC headers before storing or forwarding, keeping channels safe.

Rich Slack cards

Action label, column color dot, creator, and links—no bare JSON dumps.

Per-user slugs

No user IDs in URLs. Each slug is private, rotate anytime.

Event history

Paginated event log with collapsible payloads for troubleshooting.

How it works

Copy your unique webhook URL and add your Fizzy signing secret.

Pick the Fizzy actions to forward and connect Slack.

Send a test webhook—Bubblehook stores it and posts a formatted card.

Free till we figure out if it is worth charging

No plans, no meters, no corporate upsells. Bubblehook is free while we find out what deserves a price tag. If we ever do charge, you’ll get plenty of notice and a warm hug—not a surprise invoice.
