Xero Webhook Secure Reception and Automated Processing Workflow

Workflow Name

Xero Webhook Secure Reception and Automated Processing Workflow

Key Features and Highlights

This workflow securely receives and verifies webhook data pushed from the Xero financial system. After confirming the legitimacy of the data source, it stores the webhook data into a FileMaker database and automatically triggers subsequent processing scripts to handle the business logic. The entire process is fully automated without manual intervention, enhancing both the security and efficiency of data handling.

Core Problems Addressed

• Verifies the authenticity of webhook requests to prevent security risks from forged requests
• Automates the reception and storage of webhook data pushed by Xero
• Automatically triggers follow-up business processing scripts within the FileMaker database
• Reduces human errors and improves the reliability and timeliness of webhook data processing

Application Scenarios

• Integration scenarios between the Xero financial system and FileMaker database
• Automated business workflows requiring secure verification of webhook data sources
• Enterprise applications that need to store real-time data pushed from external systems and trigger subsequent automated processing
• Suitable for automated data processing needs in finance, auditing, billing management, and related fields

Main Workflow Steps

1. Xero Webhook Node: Listens for POST request webhooks from the Xero system and receives the raw request body
2. Move Binary Data Node: Extracts and prepares the raw webhook data
3. Set Node: Binds the raw data as the “source_data” field for subsequent processing
4. Crypto Node: Encrypts the source_data using the HMAC-SHA256 algorithm with a preset webhook secret to generate target_data
5. IF Node: Compares the encrypted target_data with the Xero signature in the request header to verify request legitimacy
6. If verified, proceeds to the Success Node, returns an HTTP 200 response, and simultaneously:
   • Create Webhook Record Node: Stores the webhook JSON data into the Webhooks layout of the FileMaker database
   • Perform processWebhook Script Node: Calls the processWebhook script in FileMaker, passing the newly created record ID to execute subsequent business processing
7. If verification fails, proceeds to the Unauthorized Node, returns an HTTP 401 response, and rejects the request

Involved Systems and Services

• Xero: Financial system serving as the webhook data sender
• n8n: Workflow automation platform responsible for data reception, verification, and process control
• FileMaker: Database system that stores webhook data and executes business scripts
• Utilized technical nodes include Webhook, Crypto (encryption), IF (conditional logic), and FileMaker database operation nodes

Target Users and Value

• Finance, accounting, and data management personnel who need to ensure the authenticity of Xero-pushed data and automate its processing
• IT operations and automation engineers building secure and reliable webhook handling workflows
• Enterprises aiming to achieve automated integration of financial system data and business process automation
• Any organizations or teams requiring secure verification, storage, and automated processing of external webhook data
