## APIs (9)

- **Webhook Relay API** — API for managing tunnels, webhooks, tokens, and functions.
- **Webhook Relay Buckets API** — Input and output grouping. Bucket allows to have multiple endpoints for the same destination or multiple destinations for fan-out style webhook forwarding.
- **Webhook Relay Domains API** — The Domains API from Webhook Relay — 2 operation(s) for domains.
- **Webhook Relay Functions API** — Webhook Relay Functions provide an easy way to extract values from webhooks and transform HTTP requests before passing them to their final destination. Function can be reused by...
- **Webhook Relay Inputs API** — Inputs are your public endpoints. Each input serves as an inbox that you can supply to your webhooks producer (ie: Github, Docker, IFTTT)
- **Webhook Relay Logs API** — Webhook logs hold the status of received and forwarded webhooks. You can use this API group to resend webhooks to one or more destinations
- **Webhook Relay Outputs API** — Outputs are destinations, where your webhooks will be forwarded. Public destinations do not require agents to be running. Internal outputs will not work without an agent.
- **Webhook Relay Tokens API** — Token key & secret pairs are used to authenticate your API calls or for agents to subscribe to webhook forwarding or open tunnels.
- **Webhook Relay Tunnels API** — Tunnels allow remote access to internal web services such as local Wordpress, Jekyll or Hexo. Recommended `crypto` options are `flexible` or `tls-pass-through`.
