Webhooks

List webhook endpoints

GEThttps://ecdsa.com/api/v1/webhooks

The webhook endpoints of the API key's account, oldest first, each with its most recent delivery, and the number of endpoints the account's plan allows. Deliveries are POST requests with a JSON body, signed with ECDSA P-256 (ES256): headers ECDSA-Webhook-Id, ECDSA-Webhook-Timestamp and ECDSA-Signature (t=<unix seconds>,kid=<key id>,es256=<base64url r‖s>) over the UTF-8 bytes of "<id>.<t>.<raw body>". The public keys are the JWKS at https://ecdsa.com/.well-known/ecdsa-webhook-keys.json; every official SDK verifies deliveries with verifyWebhook().

API key: Required, with the scope webhooks
Quota cost with a key: 1 unit per call
Rate limit: 60 requests/min per IP

Example

The account's endpoints

curl

curl -sS 'https://ecdsa.com/api/v1/webhooks' \
  -H "authorization: Bearer $ECDSA_API_KEY"

JavaScript (fetch)

const response = await fetch("https://ecdsa.com/api/v1/webhooks", {
  headers: { authorization: `Bearer ${process.env.ECDSA_API_KEY}` },
});
console.log(response.status, await response.json());

Python (httpx)

import os

Error codes

Code	Status	Meaning
unauthorized	401	The Authorization or X-API-Key header is malformed, the API key is not valid (wrong checksum, unknown, revoked or expired), or the operation needs a key.
forbidden_scope	403	The API key is valid but lacks a scope this operation requires; the message names it.
not_found	404	No operation exists at this path.
method_not_allowed	405	The path exists but does not accept this HTTP method; see the Allow header.
rate_limited	429	Too many requests — see Retry-After.
quota_exceeded	429	A daily or monthly quota of the API key's account is used up. X-Quota-Reset (and Retry-After) say when it starts over; retrying earlier cannot succeed.
internal_error	500	Unexpected server error.
service_unavailable	503	API keys cannot be verified right now (the key store is unreachable); retry shortly.
webhooks_unavailable	503	Webhooks are switched off on this server: it has no signing keys configured.
timeout	504	The operation did not finish within its time budget.
