Target Audience

  • Developers: Those looking to automate webhook data processing and validation.
    - Business Analysts: Users who need to integrate data from Xero into FileMaker for reporting and analysis.
    - IT Professionals: Individuals responsible for maintaining and optimizing API integrations.
    - Entrepreneurs: Small business owners who want to streamline their financial data handling with minimal manual intervention.

    • Problem Solved

    This workflow addresses the need for secure and automated processing of incoming webhook data from Xero. It ensures that the data is validated against a cryptographic signature, allowing businesses to confidently integrate and store this data in FileMaker without the risk of tampering.

    Workflow Steps

  • Step 1: The workflow is triggered by a POST request to the Xero webhook.
    - Step 2: The raw binary data received is moved to a designated key for further processing.
    - Step 3: The workflow sets the source_data variable from the raw data for later use.
    - Step 4: A SHA256 HMAC hash is generated using a secret key to validate the integrity of the incoming data.
    - Step 5: The generated hash is compared against the Xero signature to verify authenticity.
    - Step 6: If validation is successful, a record is created in FileMaker, and the workflow responds with a 200 OK status.
    - Step 7: If validation fails, it responds with a 401 Unauthorized status, indicating that the data is not trustworthy.

    • Customization Guide

  • Adjust Webhook Path: Modify the path parameter in the Xero Webhook node to match your specific webhook URL.
    - Change Hashing Method: Alter the type parameter in the Crypto node to use different hashing algorithms (e.g., MD5, SHA1) if needed.
    - Update FileMaker Layout: Change the layout parameter in the Create webhook record node to point to a different layout in your FileMaker database.
    - Modify Response Codes: Customize the response codes in the RespondToWebhook nodes to suit your application's requirements.
    - Add Additional Logic: Enhance the IF conditions to incorporate more complex validation rules as per your business logic.
