Webflow Enterprise Rbac

Webflow Enterprise RBAC

Overview

Enterprise-grade access control for Webflow Data API v2 integrations. Uses Webflow's OAuth 2.0 scope system, per-site token isolation, and application-level RBAC to enforce least privilege across teams and environments.

Prerequisites

• Webflow workspace (Core plan or higher for multiple members)
• OAuth 2.0 Data Client App (for user-authorized access)
• Understanding of Webflow scopes

Webflow's Native Access Model

Webflow provides three levels of access control:

Scope-Based Permission Model

Webflow scopes map directly to API access:

Instructions

Step 1: Define Application Roles

Map your application roles to Webflow scope sets:

enum AppRole {
  ContentViewer = "content_viewer",
  ContentEditor = "content_editor",
  SiteAdmin = "site_admin",
  EcommerceManager = "ecommerce_manager",
  FormProcessor = "form_processor",
}

// Map roles to required Webflow OAuth scopes
const ROLE_SCOPES: Record<AppRole, string[]> = {
  [AppRole.ContentViewer]: ["sites:read", "cms:read", "pages:read"],
  [AppRole.ContentEditor]: ["sites:read", "cms:read", "cms:write", "pages:read"],
  [AppRole.SiteAdmin]: [
    "sites:read", "sites:write",
    "cms:read", "cms:write",
    "pages:read", "pages:write",
    "custom_code:read", "custom_code:write",
  ],
  [AppRole.EcommerceManager]: [
    "sites:read",
    "ecommerce:read", "ecommerce:write",
    "cms:read", // Products are CMS collections
  ],
  [AppRole.FormProcessor]: ["sites:read", "forms:read"],
};

Step 2: OAuth App with Role-Based Scopes

Request only the scopes needed for the user's role:

function getAuthorizationUrl(role: AppRole, state: string): string {
  const scopes = ROLE_SCOPES[role];
  const scopeString = scopes.join(" ");

  return (
    `https://webflow.com/oauth/authorize` +
    `?client_id=${process.env.WEBFLOW_CLIENT_ID}` +
    `&response_type=code` +
    `&redirect_uri=${encodeURIComponent(process.env.REDIRECT_URI!)}` +
    `&scope=${encodeURIComponent(scopeString)}` +
    `&state=${state}` // CSRF protection
  );
}

// Initiate OAuth flow with role-appropriate scopes
app.get("/auth/webflow", (req, res) => {
  const role = req.user.appRole as AppRole;
  const state = generateCsrfToken(req.session.id);

  res.redirect(getAuthorizationUrl(role, state));
});

Step 3: Token Storage with Role Metadata

interface StoredToken {
  accessToken: string;
  userId: string;
  role: AppRole;
  scopes: string[];
  siteIds: string[]; // Which sites this token can access
  createdAt: Date;
  lastUsed: Date;
}

async function storeToken(token: StoredToken): Promise<void> {
  // Encrypt token before storing
  const encrypted = encrypt(token.accessToken);

  await db.webflowTokens.upsert({
    where: { userId: token.userId },
    create: {
      ...token,
      accessToken: encrypted,
    },
    update: {
      accessToken: encrypted,
      lastUsed: new Date(),
    },
  });
}

Step 4: Per-Site Token Isolation

Use site-scoped tokens to limit blast radius:

class SiteIsolatedClient {
  private clients = new Map<string, WebflowClient>();

  // Each site gets its own token — compromise of one doesn't affect others
  registerSite(siteId: string, siteToken: string): void {
    this.clients.set(siteId, new WebflowClient({ accessToken: siteToken }));
  }

  getClient(siteId: string): WebflowClient {
    const client = this.clients.get(siteId);
    if (!client) {
      throw new Error(`No token registered for site ${siteId}`);
    }
    return client;
  }

  // Rotate a single site's token without affecting others
  rotateToken(siteId: string, newToken: string): void {
    this.clients.set(siteId, new WebflowClient({ accessToken: newToken }));
    console.log(`Token rotated for site ${siteId}`);
  }
}

const siteClients = new SiteIsolatedClient();
siteClients.registerSite("site-prod", process.env.WEBFLOW_TOKEN_PROD!);
siteClients.registerSite("site-staging", process.env.WEBFLOW_TOKEN_STAGING!);

Step 5: Permission Check Middleware

import { Request, Response, NextFunction } from "express";

function requireWebflowScope(requiredScopes: string[]) {
  return async (req: Request, res: Response, next: NextFunction) => {
    const userToken = await db.webflowTokens.findByUserId(req.user.id);

    if (!userToken) {
      return res.status(401).json({ error: "No Webflow authorization" });
    }

    // Check if user's token has the required scopes
    const missingScopes = requiredScopes.filter(
      s => !userToken.scopes.includes(s)
    );

    if (missingScopes.length > 0) {
      return res.status(403).json({
        error: "Insufficient Webflow permissions",
        missing: missingScopes,
        userRole: userToken.role,
        hint: `Role "${userToken.role}" does not include: ${missingScopes.join(", ")}`,
      });
    }

    next();
  };
}

// Usage
app.post(
  "/api/cms/items",
  requireWebflowScope(["cms:write"]),
  createItemHandler
);

app.get(
  "/api/forms/submissions",
  requireWebflowScope(["forms:read"]),
  listSubmissionsHandler
);

app.post(
  "/api/site/publish",
  requireWebflowScope(["sites:write"]),
  publishSiteHandler
);

Step 6: Audit Logging

interface WebflowAuditEntry {
  timestamp: Date;
  userId: string;
  role: AppRole;
  operation: string;
  siteId: string;
  resourceType: string;
  resourceId?: string;
  result: "success" | "denied" | "error";
  scopes: string[];
  ipAddress: string;
}

async function auditWebflowAccess(entry: WebflowAuditEntry): Promise<void> {
  // Write to audit log (never delete audit entries)
  await db.auditLog.create({
    data: {
      ...entry,
      timestamp: entry.timestamp.toISOString(),
    },
  });

  // Alert on suspicious patterns
  if (entry.result === "denied") {
    console.warn(`ACCESS DENIED: ${entry.userId} attempted ${entry.operation} on ${entry.resourceType}`);
  }

  // Alert on admin operations
  if (entry.role === AppRole.SiteAdmin && entry.operation.includes("publish")) {
    console.log(`ADMIN ACTION: ${entry.userId} published site ${entry.siteId}`);
  }
}

// Wrap API calls with audit logging
async function auditedCall<T>(
  entry: Omit<WebflowAuditEntry, "timestamp" | "result">,
  operation: () => Promise<T>
): Promise<T> {
  try {
    const result = await operation();
    await auditWebflowAccess({ ...entry, timestamp: new Date(), result: "success" });
    return result;
  } catch (error) {
    await auditWebflowAccess({ ...entry, timestamp: new Date(), result: "error" });
    throw error;
  }
}

Step 7: Token Rotation Schedule

async function checkTokenAge(): Promise<void> {
  const tokens = await db.webflowTokens.findMany();

  for (const token of tokens) {
    const ageInDays = (Date.now() - token.createdAt.getTime()) / (1000 * 60 * 60 * 24);

    if (ageInDays > 90) {
      console.warn(
        `Token for user ${token.userId} (${token.role}) is ${Math.floor(ageInDays)} days old. ` +
        `Rotation recommended.`
      );
      // Send notification to user/admin
    }
  }
}

// Run weekly
// cron: "0 9 * * 1"
