Enhanced OAuth2.0 Token Refresh for Pipedrive CRM with Supabase

This n8n workflow template provides an advanced OAuth 2.0 authorization flow for Pipedrive CRM, utilizing Supabase as a database to store and manage access tokens and refresh tokens. It addresses common issues with n8n's native OAuth implementation, such as manual token refreshes and lack of visibility, by automating the entire process: capturing the authorization code, exchanging it for tokens, and securely storing them for reuse.

The solution consists of multiple interconnected workflows. The first captures the initial authorization code from Pipedrive's OAuth endpoint, generates access and refresh tokens, and saves them to Supabase. Subsequent workflows fetch fresh tokens automatically when needed, ensuring seamless API access without interruptions. This is ideal for developers building CRM automations who need reliable, long-term authentication.

Benefits include improved security through database-stored tokens, easy adaptability to other APIs requiring OAuth 2.0 (e.g., Google, Microsoft), and significant time savings by eliminating manual interventions. Use cases span sales pipelines, lead management, and custom integrations where token expiry disrupts operations. Setup requires a Supabase table and Pipedrive app credentials, with a demo video for guidance.
