How to integrate Crowdin with Webflow

Crowdin's integration transforms your Webflow site into a multilingual powerhouse through automated content synchronization and real-time translation management.

While the primary method uses Crowdin's official Webflow app for seamless setup, you can also build advanced workflows using both platforms' APIs for complete control over localization pipelines.

Use the Crowdin marketplace app

The Crowdin app provides the fastest path to multilingual Webflow sites.

Install it directly from Webflow's Apps panel, then connect your Crowdin account to enable automatic content synchronization. The app extracts your site's static content from Webflow Pages, CMS, and component props and content. Then, the app syncs those pieces of content with Crowdin for translation and deploys updates via a lightweight JavaScript snippet.

Key capabilities include:

• Daily automatic synchronization pulls new content and pushes completed translations
• Flexible language switcher customization for position and styling
• Collection support for translating CMS content alongside static pages
• Component support for translating static content in components, as well as component properties

Setup requires purchasing Crowdin's Webflow Localization Subscription Plan, then configuring sync settings in your Crowdin project dashboard.

The integration handles content mapping automatically, eliminating manual file transfers.

Build with Webflow and Crowdin APIs

For workflows where you may need a custom solution, you can build your own integration using Webflow’s Data API and Crowdin’s API v2.This approach requires server-side implementation through AWS Lambda, Netlify Functions, or similar services.

Use Crowdin’s REST API v2 for translation management and Webflow’s Data API for content synchronization. Key capabilities include branch-based staging workflows, and webhook-driven automation.

Automate CMS translation workflows

1. Configure a Webflow webhook to fire on CMS item create/update/delete events via the Create Webhook endpoint.
2. In your serverless function or custom integration, fetch changed items with List Collection Items and diff against previous versions.
3. Push source text to Crowdin using Add File (standard plans) or Add Storage (Enterprise only) to create translatable resources.
4. Listen for Crowdin file.translated webhooks to detect completed translations.
5. Retrieve translated files via Build Project Translation and update Webflow CMS items.
6. Call Webflow’s Publish Site endpoint after CMS updates to publish translations live, or use the Live APIs to create or update CMS items on the live site.

Implement quality gates

1. Enforce terminology consistency by uploading glossaries via the Glossary API; glossary rules apply during translation in Crowdin’s editor.
2. Use the Translation Status endpoint to verify all segments are approved before triggering publish.
3. Monitor Webflow rate limits via HTTP response headers (X-RateLimit-Limit, X-RateLimit-Remaining).

Scale multi-site operations

1. Create branches in Crowdin via the API and map them to Webflow projects in Crowdin’s UI — there is no automated branch_mapping parameter.
2. Batch update multiple collections by iterating through sites and collections in your serverless logic.
3. Implement language fallbacks by checking for missing translations in your code and defaulting to the source language when needed.

What you can build

Integrating Crowdin with Webflow opens possibilities for sophisticated multilingual experiences that scale globally.

• Multi-regional marketing sites: Deploy localized landing pages with in-context previews that preserve layout. Leverage branch-based staging workflows to A/B test regional versions before publishing.
• Knowledge bases and documentation: Sync Webflow CMS collections on a schedule to keep versioned help articles aligned across languages automatically. Use glossary enforcement and translation status checks to maintain technical accuracy.
• Community-driven platforms: Enable crowdsourced translations with Crowdin’s translation memory, glossaries, and reviewer workflows via OTA JS or REST API. Implement role-based access controls to manage contributor permissions and workflows.
