Form Sparrow

How to integrate Form Sparrow with Webflow

Webflow's native forms work well for hosted sites, but Form Sparrow extends its functionality with advanced validation, file handling, and form support for exported sites. Form Sparrow processes submissions on exported static sites where Webflow's native forms stop working.

You can connect Form Sparrow to Webflow through embedded HTML forms or by building custom workflows with Webflow's API.

Embed Form Sparrow with Webflow's Code Embed element

Webflow's Code Embed element lets you add HTML forms directly to your pages. This method works for both Webflow-hosted sites and exported projects, supporting up to 10,000 characters of code per embed.

Create a Form Sparrow account and generate your unique action URL from the dashboard. In Webflow, drag a Code Embed element onto your page. Paste your HTML form code with the action URL pointing to Form Sparrow's endpoint. Set the form method to POST and add name attributes to all input fields.

Form Sparrow supports these capabilities:

• File uploads using enctype="multipart/form-data" on the form tag
• Custom email subjects through hidden input fields
• Dynamic reply-to addresses using form field values
• Honeypot spam protection via hidden fields following Form Sparrow's documentation patterns
• Post-submission redirects to custom thank you pages

Forms submit directly to Form Sparrow's endpoint without JavaScript requirements, though you can add custom scripts for enhanced functionality. This approach works well when you need form functionality on exported Webflow sites or advanced file handling that Webflow's native forms don't provide.

Build with Webflow and Form Sparrow APIs

Webflow's REST API enables programmatic form management and submission handling. Combine this with Form Sparrow's endpoint structure for custom workflows that route data between systems.

Manage forms programmatically

Webflow's API provides endpoints for form operations across your sites. Retrieve form configurations, access submissions, and manage form data through authenticated requests.

Key API endpoints include:

• List site forms with GET /v2/sites/:site_id/forms to retrieve all form configurations
• Get form submissions using GET /forms/{form_id}/submissions with pagination support
• Delete submissions through DELETE /formsubmissions/{formsubmission_id} for data management

Authentication requires Bearer tokens with appropriate scopes. The authorization documentation details scope requirements for forms:read and forms:write operations.

Use these endpoints to build custom form management dashboards, automate submission processing, or sync form data with external systems. The API returns structured JSON responses with complete form metadata and submission details.

Sync form data to CMS collections

Webflow's CMS API lets you create collection items from form submissions. Process submissions through Form Sparrow, then use Webflow's API to store structured data in CMS collections.

Implementation workflow:

• Create CMS items with POST /v2/collections/:collection_id/items from submission data
• Update existing items using PATCH /v2/collections/:collectionid/items/:itemid for data modifications
• Publish items through POST /v2/collections/:collection_id/items/publish to make content live

This pattern works for user-generated content sites, directory submissions, or workflows where form data becomes structured site content. Monitor form submissions via Webflow's form webhook notifications or API polling, then use Webflow's CMS API to create corresponding CMS entries based on submission data.

The CMS API requires cms:read and cms:write scopes. Field data must match the collection schema defined in Webflow.

What you can build

Integrating Form Sparrow with Webflow gives you flexible form handling across static sites, hosted projects, and complex data workflows.

• Lead qualification forms: Build multi-step forms that collect detailed prospect information, validate data against custom rules, and route qualified leads to sales teams based on company size, industry, or region
• Document collection portals: Create intake forms where clients upload contracts, proposals, or project files with automatic email delivery to appropriate teams and organized file storage
• Event registration systems: Design registration forms with file upload support, payment processing integration, and automated confirmation emails with calendar invitations
• Support ticket intake: Build help desk forms that categorize issues, attach screenshots or logs, route tickets to specialized teams, and trigger automated acknowledgment workflows
