How to integrate MeldAPI with Webflow

The easiest way to set up your MeldAPI Webflow integration is by installing the MeldAPI app from the Webflow Apps marketplace. The app provides a visual interface for mapping fields between external data sources and your Webflow CMS, with sync scheduling, data filters, and auto-publishing, all without code.

For programmatic control like triggering syncs from external systems, monitoring sync status, or building custom workflows, you can also build with the MeldAPI API. MeldAPI's developer documentation provides endpoints for sync triggering, connection management, and webhook notifications.

Note: MeldAPI is currently in beta. The Getting Started documentation advises using test data during initial setup and monitoring sync results closely before relying on it for production workflows.

Use the MeldAPI app

Install the MeldAPI app from the Webflow Apps marketplace. After installation, you authenticate your Webflow site, create "Melds" (sync configurations), and map source fields to Webflow CMS collection fields using a visual drag-and-drop interface. MeldAPI operates entirely as a backend sync platform. No embed codes or client-side scripts are added to your Webflow site.

Supported source connectors include Airtable, Guesty, SeaTable, OpenAI, Dropbox, Mailchimp, and OpenWeather.

Set up a Webflow CMS sync

1. Prepare your CMS collections in Webflow with fields that match your source data structure
2. Generate an API token in your Webflow site settings under Apps & Integrations → API Access with appropriate read/write permissions
3. In MeldAPI's dashboard, create a Webflow connection using your API token
4. Create a source connection for your external app (Airtable, Guesty, etc.)
5. Build a Meld linking the two connections and map fields using the visual interface
6. Configure your sync trigger (manual, scheduled, or real-time)
7. Use the preview sync feature to verify your configuration before running a live sync

Automate form-to-CMS workflows

MeldAPI can create CMS items from Webflow form submissions automatically. No client-side code needed. Set up a Meld with your Webflow form as the source and a CMS collection as the destination. Map form fields to collection fields, apply any data filters or transformations, and enable auto-publish if you want new items to appear on your live site immediately.

For multi-step workflows, use MeldAPI's Flows feature to chain Melds together. For example, routing form data to both a CMS collection and an external tool like Mailchimp.

Webflow enforces form submission limits based on your site plan. Check your Webflow dashboard for current usage and limits.

Build with the MeldAPI API

For developers who need programmatic control over sync operations, MeldAPI provides a REST API at https://api.meldapi.io/api/public/v1/. This is an advanced, developer-level integration — useful for triggering syncs from external systems, building monitoring dashboards, or integrating MeldAPI into larger automation pipelines.

All API requests require authentication in the format Authorization: Bearer <API_TOKEN>. See the MeldAPI developer documentation for authentication details, endpoint reference, and error response formats.

Available endpoints:

• GET /api/public/v1/auth/check to confirm your token is valid
• GET /api/public/v1/connections/:id to inspect connection state
• GET /api/public/v1/meldsyncs/add/:meld_id to start a sync operation programmatically
• GET /api/public/v1/meldsyncs/processing to check real-time progress of currently processing syncs
• Receive notifications on sync completion or failure, including record counts and error arrays

Store API keys in environment variables and route all API calls through a backend server to protect credentials.

Trigger syncs from external events

Use the sync trigger endpoint to start MeldAPI syncs from any system that can make HTTP requests. For example, when a record updates in your CRM, your backend calls MeldAPI's trigger endpoint to push that change into your Webflow CMS collection.

Pair this with MeldAPI's outgoing webhooks to create event-driven automation. After a sync completes, MeldAPI sends a webhook payload to your endpoint with sync status, record change counts, and any errors.

Monitor connection statuses programmatically to catch issues early. Connections can enter EXPIRED, RECONNECT_REQUIRED, or DEGRADED states that require manual intervention. Set up email notifications or outgoing webhooks in MeldAPI to detect these state changes.

What you can build

Integrate MeldAPI with Webflow to automate backend data synchronization between your CMS and external tools, keeping content current without manual updates.

• Real estate and property listing sync: Connect Guesty or Airtable to your Webflow CMS to automatically update property listings, availability, and pricing. When property details change in your management system, the corresponding Webflow CMS item updates through MeldAPI's scheduled or real-time sync.
• Form-to-CMS content pipeline: Turn Webflow form submissions into CMS items automatically. Use this to collect testimonials, user-submitted directory entries, or community content and publish it directly to your site's CMS collections.
• Editorial and catalog management: Sync blog posts, team member profiles, or product catalog data from Airtable or SeaTable into Webflow CMS collections. Content teams work in their preferred tools while the Webflow site stays up to date.
• Event-driven multi-step automation: Use the MeldAPI API to trigger syncs from external systems like CRMs, then chain multiple Melds together with Flows to run sequential operations — syncing data, transforming fields, and publishing updates in a single automated sequence. This requires developer resources and backend infrastructure.
