Get Typescript Types from Management API with Legacy Keys Disabled?

🟡javascript

Hello

Following Supabase for Platforms announcement, I was delighted to figure out that we can now fetch Typescript types programmatically from the Management API.
But, it looks like it does not work if the target project has moved to the new API Keys, which is weird since the Management API seems a bit unrelated to the Data API from my perspective.

I get an error :


{
  "message": "{\"message\":\"Legacy API keys are disabled\",\"hint\":\"Your legacy API keys (anon, service_role) were disabled on 2025-11-13T10:41:23.346309+00:00. Re-enable them in the Supabase dashboard, or use the new publishable and secret API keys.\"}"
}


{
  "message": "{\"message\":\"Legacy API keys are disabled\",\"hint\":\"Your legacy API keys (anon, service_role) were disabled on 2025-11-13T10:41:23.346309+00:00. Re-enable them in the Supabase dashboard, or use the new publishable and secret API keys.\"}"
}

Code snippet:

    console.log(`:satellite: Fetching TypeScript types for project: ${supabaseHosting.project_id}`);

    // Step 3: Get Management API token from environment
    const managementApiToken = process.env.SUPABASE_MANAGEMENT_API_TOKEN;
    if (!managementApiToken) {
      throw new Error('SUPABASE_MANAGEMENT_API_TOKEN environment variable is required');
    }

    // Step 4: Call Supabase Management API to fetch TypeScript types
    const response = await fetch(
      `${MANAGEMENT_BASE}/projects/${supabaseHosting.project_id}/types/typescript`,
      {
        method: 'GET',
        headers: {
          'Authorization': `Bearer ${managementApiToken}`,
          'Content-Type': 'application/json',
        },
      }
    );

    if (!response.ok) {
      const errorText = await response.text();
      throw new Error(`Management API request failed: ${response.status} ${response.statusText}. ${errorText}`);
    }

    console.log(`:satellite: Fetching TypeScript types for project: ${supabaseHosting.project_id}`);

    // Step 3: Get Management API token from environment
    const managementApiToken = process.env.SUPABASE_MANAGEMENT_API_TOKEN;
    if (!managementApiToken) {
      throw new Error('SUPABASE_MANAGEMENT_API_TOKEN environment variable is required');
    }

    // Step 4: Call Supabase Management API to fetch TypeScript types
    const response = await fetch(
      `${MANAGEMENT_BASE}/projects/${supabaseHosting.project_id}/types/typescript`,
      {
        method: 'GET',
        headers: {
          'Authorization': `Bearer ${managementApiToken}`,
          'Content-Type': 'application/json',
        },
      }
    );

    if (!response.ok) {
      const errorText = await response.text();
      throw new Error(`Management API request failed: ${response.status} ${response.statusText}. ${errorText}`);
    }

With the exact same project, I can apply migrations from the Management API without any troubles.
