create_bin~132 tokens
Create a new webhook capture bin. Returns a public capture_url — point any webhook (Stripe, GitHub, Slack, your own service…) at it and every request sent there (any method, any subpath, headers + raw body) is stored. Then read what arrived with list_captures, get_capture, or wait_for_capture. Anonyget_capture~129 tokens
Get one captured request in full: method, path, query, every header, and the body. Binary bodies are returned base64-encoded (up to 8KB, with a URL for the raw bytes).list_captures~176 tokens
List requests captured by a bin, oldest first. Compact summaries (id, method, path, time, content-type, body size, signature status). Use get_capture for full headers/body. Pass `after` (a capture id) to only see newer captures.send_test_webhookSends messages · ~256 tokens
Simulate a webhook delivery into a bin — no external sender or HTTP client needed. Seeds one realistic, clearly-labeled sample capture (default: a GitHub push event) and returns it in full, so you can exercise the whole loop (create_bin → send_test_webhook → list_captures / get_capture) entirely froset_response~520 tokens
Configure what a bin replies to webhook senders: HTTP status, content-type, body, custom response headers, optional delay. Body and header values support {{…}} templates rendered per-request from the INCOMING delivery — {{body.challenge}}, {{query.hub.challenge}}, {{header.x-hook-secret}}, {{hmac_shverify_signature~613 tokens
Verify a webhook signature against a secret — 25 provider-exact schemes plus a generic HMAC mode, the same engine that computes ✓/✗ badges on captures. Covers HMAC-SHA256 (GitHub, Stripe, Svix/Standard Webhooks, Shopify-style base64, URL-signing Square/HubSpot/Trello…), ECDSA (SendGrid), RSA (Kick)wait_for_capture~208 tokens
Block until the next request arrives at a bin (or a timeout passes), then return it in full. Ideal flow: create_bin → configure the webhook sender → trigger it → wait_for_capture. If `after_id` is omitted, waits for the next capture after "now". Returns timed_out:true instead of erroring when nothin
