How to integrate Memberstack with Webflow

Memberstack offers multiple integration paths tailored to different technical skill levels and project requirements.

The way to integrate Membertack with Webflow is through the official Webflow app. You can also use code embeds for authentication flows or build advanced features using Memberstack's APIs for custom workflows and third-party synchronization.

Use the Memberstack app

The official Memberstack app streamlines integration directly within Webflow's interface. Install it from the Apps panel to automatically apply data attributes to forms, buttons, and content sections without manual coding.

Key capabilities include:

• One-click attribute assignment for signup forms and login buttons
• Visual content gating by selecting elements and choosing member-only visibility
• Automated script injection eliminating manual header code placement
• Real-time preview of member vs non-member experiences

The app reduces setup time from hours to minutes by handling technical configurations automatically. For example, selecting a form and toggling "Signup" instantly adds all required data-ms-form attributes.

Use code embeds and native features

Webflow's native capabilities combined with Memberstack's embed methods enable membership functionality without the app:

Script installation requires adding Memberstack's header code to Site Settings > Custom Code:

<script src="https://static.memberstack.com/scripts/v1/memberstack.js" 

        data-memberstack-app="YOUR_APP_ID"></script>

Authentication forms use data attributes on native Webflow elements:

• Add data-ms-form="signup" to form blocks
• Apply data-ms-member="email" to email inputs
• Use data-ms-modal="login" on buttons for pre-built modals

Content gating leverages conditional visibility:

• Hide elements with data-ms-content="members"
• Show upgrade prompts with data-ms-content="!premium"
• Display member data using data-ms-member="name"

Payment integration connects through Stripe attributes:

• data-ms-price:add="PRICE_ID" creates checkout buttons
• data-ms-action="customer-portal" enables billing management

Build with Webflow and Memberstack APIs

Direct API integration unlocks advanced capabilities beyond visual tools, enabling custom authentication flows, automated member management, and complex data synchronization. This approach suits teams needing programmatic control over member experiences or integration with existing backend systems.

The API ecosystem includes the DOM package for frontend interactions, Admin REST API for server operations, and webhook endpoints for real-time updates.

Automate member provisioning

Create members programmatically when users complete actions outside standard forms:

1. Configure server endpoint to receive triggers from Webflow forms or third-party services
2. Call Admin API to create members with custom attributes via POST /v1/members:
   curl -X POST "https://admin.memberstack.com/v1/members" \

  -H "X-API-KEY: sk_live_..." \

  -d '{"email": "user@example.com", "password": "temp123", "customFields": {"source": "webinar"}}'

3. Assign plans automatically based on purchase history or engagement level
4. Sync to Webflow CMS using the member ID as a reference for profile pages

The Admin API documentation provides endpoints for bulk operations, custom field management, and plan assignments.

Build dynamic member dashboards

Combine Memberstack data with Webflow CMS for personalized experiences:

1. Fetch member data using getCurrentMember() from the DOM package
2. Query-related content from Webflow CMS based on member preferences
3. Update member JSON to store progress, bookmarks, or settings via updateMemberJSON()
4. Display analytics by aggregating member activity through webhook events

The DOM package reference details client-side methods for real-time member interactions.

Implement custom SSO flows

Enable single sign-on (SSO) across multiple domains or services:

1. Configure OAuth endpoints at https://auth.memberstack.com/authorize
2. Exchange tokens between services using the Admin API's verify endpoint
3. Sync sessions across domains with cross-origin cookie settings
4. Handle token refresh for seamless authentication persistence

The SSO integration guide covers OIDC configuration and token management.

Note: You need a Memberstack Business plan or higher to enable SSO features.

What you can build

Integrating Memberstack with Webflow enables sophisticated membership experiences while maintaining complete design control.

• Educational platforms with gated lessons: Build course websites where video content, downloadable resources, and quizzes unlock based on membership tiers, with automated enrollment emails and progress dashboards
• Digital agency client portals: Create branded workspaces where clients access project files, view invoices, and communicate with teams through member-only sections synced with project management tools
• Creator communities with exclusive content: Develop fan sites offering backstage content, early releases, and direct messaging between creators and premium members, with social login options for easy access
• Job boards with dual-sided access: Design platforms where employers post listings behind paywalls while job seekers create profiles and apply through member dashboards, with automated matching based on skills
