Fix Figma Weave Error 403 Forbidden

A 403 Forbidden error when working with Figma Weave indicates that the API endpoint successfully received your authentication credentials, but refuses to authorize the request. Unlike a 401 Unauthorized error—which points to an invalid, missing, or expired token—a 403 response means your authentication is valid, but the system has determined you do not have permission to access the requested resource.

This issue usually stems from misconfigured OAuth scopes, enterprise-level admin blocks, network restrictions, or improperly structured headers in your SDK integration. Use this step-by-step troubleshooting guide to isolate and resolve the error.

1. Verify and Update Token Scopes If you are using an OAuth token or a Personal Access Token (PAT) to authorize Figma Weave, the token must be granted the specific scopes required by the endpoints you are calling.

1. Log in to your Figma Account Settings and navigate to the Developer tab.
2. Review the permissions assigned to the token or the OAuth app registration used by your Figma Weave config.
3. Ensure the scopes cover the specific design resources you are requesting. Figma Weave requires files:read to access design files, frames, and components. If your integration reads or writes design tokens, ensure that file_variables:read or file_variables:write are explicitly enabled.
4. If using an OAuth application, update the requested scopes in your authorization flow, prompt the user to re-authorize, and obtain a fresh access token.

2. Check Figma Organization and File Permissions Figma Weave enforces the same permission model as the standard Figma interface. If the account associated with your API token cannot access the design file via the Figma app, the API will return a 403 error.

1. Confirm that the owner of the API token has at least "Can View" (or "Can Edit" if attempting write operations) permissions on the specific Figma files or libraries being processed.
2. If you are trying to access a file in a different team or organization workspace, verify that your account has been added to that workspace.
3. For Enterprise plans, ask your Figma Organization Admin to check the Admin Settings. Admins can restrict third-party API integrations or block custom developer apps from accessing organizational data. If restricted, your app's Client ID must be explicitly whitelisted.

3. Fix SDK Header and Proxy Configurations If you proxy Figma Weave requests through an API gateway, a serverless function, or a custom backend wrapper, headers may be stripped or altered during transit, triggering security blocks.

1. Check your network requests to ensure your custom client configuration is not dropping the X-Figma-Token or standard Authorization: Bearer <TOKEN> header.
2. Verify that you are not sending duplicate authentication headers. For example, sending both a personal_token query parameter and an Authorization header can confuse Figma's gateway routing and result in a 403 error.
3. Address CORS (Cross-Origin Resource Sharing) restrictions. If you are making direct client-side requests from a local development environment (such as localhost:3000), Figma's security filters may reject the origin. Always route your Weave requests through a secure backend proxy rather than initiating them directly from the browser.

4. Resolve Web Application Firewall (WAF) IP Blocks In some cases, Figma's edge security services (such as Cloudflare) may trigger a 403 Forbidden error instead of a 429 Too Many Requests if they detect automated traffic that matches scraping or abuse patterns.

1. Pause all automated script runs, testing pipelines, or CI/CD actions targeting the Weave API for 15 minutes.
2. If you are routing your requests through a shared VPN or a proxy pool, try switching to a dedicated IP address. Shared IP ranges often trigger blocklists due to high traffic volumes from other users.
3. Implement exponential backoff in your integration code to ensure your system gracefully handles high-volume requests without triggering automated firewall defenses.

When to escalate If you have confirmed that your scopes are correct, the token owner has access to the design file, and your IP is not blocked, the issue may be a backend service disruption on Figma's end. Check the official Figma Status page to see if there are active API or developer platform outages. If services are operational, reach out to Figma Support or post on the Figma developer forum, providing your Integration ID, the exact endpoint being hit, and the timestamp of the 403 response.
