Direct integration

The Yieli API is OAuth 2.0 (client-credentials) with HMAC-SHA256 signed webhooks. The endpoints below are the intended shape for the v1 public API. During private beta, request access at /waitlist with the subject “API access.”

  "client_secret": "YOUR_CLIENT_SECRET",
  "scope": "read:sales read:briefs write:bids"
}
