This n8n workflow securely processes contact form submissions by validating user input, formatting the data, and storing it in a MongoDB database. The flow ensures data consistency, prevents unsafe entries, and provides a confirmation response back to the user. Workflow 1. Form Submission Node Purpose: Serves as the workflow’s entry point. Functionality: Captures user input from the contact form, which typically includes: name last name email phone number 2. Code Node (Validation Layer) Purpose: Ensures that collected data is valid and secure. Validations performed: Removes suspicious characters to mitigate risks like SQL injection or script injection. Validates the phone_number field format (numeric, correct length, etc.). If any field fails validation, the entry is marked as “is_not_valid” to block it from database insertion. 3. Edit Fields Node (Data Formatting) Purpose: Normalizes data before database insertion. Transformations applied: Converts field names to snake_case (first_name, last_name, phone_number). Standardizes field naming convention for consistency in MongoDB storage. 4. MongoDB Node (Insert Documents) Purpose: Persists validated data in MongoDB Atlas. Process: Inserts documents into the target collection with the cleaned and formatted fields. Connection is established securely using a MongoDB Atlas connection string (URI). 🔧 How to Set Up MongoDB Atlas Connection URL a. Create a Cluster b. Log in to MongoDB Atlas and create a new cluster. c. Configure Database Access: Add a database user with a secure username and password, Assign appropriate roles (e.g., Atlas Admin for full access or Read/Write for limited). d. Obtain Connection String (URI) From Atlas, go to Clusters → Connect → Drivers. Copy the provided connection string, which looks like: mongodb+srv://<username>:<password>@cluster0.abcd123.mongodb.net/myDatabase?retryWrites=true&w=majority Configure in n8n In the MongoDB node, paste the URI. Replace <username>, <password>, and myDatabase with your actual credentials and database name. Test the connection to ensure it is successful. 5. Form Ending Node Purpose: Provides closure to the workflow. Functionality: Sends a confirmation response back to the user, indicating that their contact details were successfully submitted and stored. ✅ Result: With this workflow, all contact form submissions are safely validated, normalized, and stored in MongoDB Atlas, ensuring both data integrity and security basic.
