Overview
This workflow automates the validation of JSON strings received via a webhook in n8n. It ensures that any JSON data submitted to the endpoint is checked for correctness and provides immediate feedback to the sender.
Key Features
- Webhook Input: Receives JSON strings from external sources through a secure webhook endpoint.
- Automated Validation: Utilizes a code node to parse and validate the JSON string, detecting syntax errors or malformed data.
- Instant Response: Sends a structured response back to the requester, indicating whether the JSON is valid or contains errors.
- Documentation Notes: Includes sticky notes within the workflow for clarity on input expectations, validation logic, and response structure.
Benefits
- Error Prevention: Quickly identifies invalid JSON before further processing, reducing downstream errors.
- Time Savings: Automates manual validation, saving developer and business user time.
- Reliability: Ensures only well-formed data enters your systems, improving data quality.
Use Cases
- API Gateways: Pre-validate JSON payloads before processing in APIs.
- Data Ingestion Pipelines: Ensure incoming data from forms or integrations is correctly formatted.
- Developer Tools: Provide instant feedback for developers testing JSON payloads.
Integrations & Processes
- Leverages n8n's webhook and code nodes for seamless integration and custom logic.
- Can be extended to trigger further automations based on validation results.
