Get secure accounting updates into your system without manual work. Incoming events from Xero are checked for authenticity, saved in Claris FileMaker, and handed to a script for fast follow up. Teams that track invoices, contacts, or payments in a custom FileMaker app will see faster handling and cleaner records.

An HTTP endpoint receives each Xero webhook with the raw body kept intact. A SHA256 HMAC is computed using your secret and compared to the Xero signature header. Valid requests get a 200 response right away, then the raw JSON is written to the Webhooks layout in FileMaker. A FileMaker script named processWebhook runs next and receives the new record id so your app can take action. If the signature check fails, a 401 response is returned and nothing is stored.

Setup is simple. You need a Xero webhook key and a FileMaker account with API access. Put the secret in the hash step, connect your FileMaker credentials, and point the Xero webhook to the n8n URL. Expect lower handling time, fewer errors from copy and paste, and a clear audit trail in FileMaker for every accepted event.

• Receives POST requests on a webhook endpoint and preserves the exact raw body
• Moves binary raw data into JSON so it can be hashed and stored cleanly
• Computes a SHA256 HMAC using your secret and encodes the result in base64
• Compares the computed hash to the x xero signature header to verify authenticity
• Returns 200 for valid requests and 401 for invalid requests immediately
• Creates a record in the Webhooks layout in Claris FileMaker with the raw JSON payload
• Calls a FileMaker script named processWebhook and passes the new record id for downstream actions

• Reduce manual logging from 1 hour to 5 minutes per batch by capturing events automatically
• Improve data accuracy by verifying 100 percent of events with a signature check
• Connect Xero and Claris FileMaker seamlessly with no custom code
• Handle up to 10 times more webhook volume with fast 200 responses before processing
• Create a clear audit trail by storing the exact raw JSON for each accepted event

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You will need accounts with Xero and Claris FileMaker. See the Tools Required section above for links to create accounts with these services.
3. In Xero, create or open your webhook in the developer portal and note the webhook key. This key is used to sign each request.
4. Open the Webhook node in n8n and copy the production URL. Paste this URL into your Xero webhook configuration so events reach n8n.
5. Double click the Crypto node and set the Secret field to your Xero webhook key. Leave the algorithm as SHA256 and the output as base64.
6. Confirm the Webhook node has Raw Body enabled and that Move Binary Data writes to a raw_data field. The Set node should map raw_data into source_data and keep only that field.
7. Double click the Create webhook record node. In the Credential to connect with dropdown, click Create new credential, then follow the on screen steps to connect your Claris FileMaker server. Name the credential clearly, such as FileMaker Production.
8. Repeat the same credential selection for the Perform processWebhook script node so both nodes use the same FileMaker connection.
9. In the Perform processWebhook script node, confirm the script name is processWebhook and the parameter uses the created record id as shown in the template.
10. Send a test event from Xero. In n8n, check the execution. You should see a 200 response on the success path and then a new record created in FileMaker.
11. If you receive a 401 response, verify the Crypto secret matches the Xero webhook key and that the header x xero signature is present. Make sure the raw body is not altered by any node before hashing.
12. Turn the workflow on in n8n Cloud and keep the URL stable. Monitor the FileMaker Webhooks layout to confirm new events are saved and processed.
