Streamline CNPJ Lookup with n8n & Minha Receita API

Effortlessly Verify CNPJ Details with n8n & Minha Receita API Integration

Streamline your Brazilian company validation process with our innovative n8n workflow designed to automate CNPJ lookups. Effortlessly receive, validate, and process CNPJ entries through the Minha Receita API, ensuring you receive up-to-date registration details directly from the source. Simplify your operational tasks with ease and confidence.

What This Workflow Does

• Accepts a CNPJ number via an n8n form submission.
• Validates the input by cleaning and ensuring the CNPJ contains exactly 14 digits.
• Configures the base URL for the Minha Receita API and sets up the “Search Again” redirect URL.
• Queries the public Minha Receita API for complete company registration details once the CNPJ is validated.
• Presents a formatted results page displaying essential company information, such as status, CNAE, partners, and address, if the API returns data successfully.
• Generates an error page when the CNPJ is incorrect or the API request fails, with an easy redirect option back to the form for re-search.
