Title:

OAuth app with valid client_id returns "doesn't exist" on figma.com/oauth endpoint — private app published to team

Description:

We created a private OAuth app via figma.com/developers/apps, published it to our team (Creative AdBundance), and configured a redirect URI. However, when we try to authorize using the standard OAuth URL:

https://www.figma.com/oauth?client_id=8eKIYXCkESoJweas8kHFwX&redirect_uri=https://www.figma.com/oauth/mcp/callback&scope=file_content:read&state=n8n&response_type=code

We get: "OAuth app with client id 8eKIYXCkESoJweas8kHFwX doesn't exist"

The client_id is confirmed correct — it matches exactly what's shown in the OAuth credentials page of our developer dashboard. The app status shows as Private, published to Creative AdBundance.

We've tried:

• Different redirect URIs (our own server + https://www.figma.com/oauth/mcp/callback)
• Different scope combinations
• Multiple browsers and incognito mode
• A second app created by the team Owner — same error

Figma support confirmed the MCP OAuth flow is only for Figma Make. We're trying to use a standard OAuth 2.0 authorization_code flow to get an access token for the Figma REST API.

Has anyone successfully gotten a private OAuth app to work with the figma.com/oauth authorization endpoint? Is there a step we're missing after publishing?
