Webflow–Salesforce API Integration for Complex Form Handling

Designed and implemented a seamless API integration between Webflow and Salesforce to support complex form data capture and CRM automation. The project involved creating multi-step, conditional forms in Webflow that collected detailed user input then securely transmitted the data to Salesforce as a new contact or updates an existing contact if applicable.

Skills Demonstrated:

  • Engineered custom JavaScript logic to manage form complexity, validation, and conditional logic within Webflow’s limitations.
  • Developed secure middleware using Make back-end to authenticate and relay form submissions to Salesforce’s REST API.
  • Mapped form fields to dynamic Salesforce objects and ensured compatibility with lead routing, campaign tracking, and custom workflows.
  • Implemented error handling, API throttling safeguards, and fallback alerts for failed submissions to maintain data integrity.
  • Reduced manual data entry by 100% and improved lead response time.

This project enabled marketing and sales teams to capture high-quality leads directly from a Webflow-built front-end, while maintaining Salesforce as the single source of truth.
