Log phone call time to the right ticket without typing. A webhook collects call details, checks a sheet for the ticket number, and creates a time entry in your ticket system. Great for IT service teams that track billable time from inbound or outbound calls.

Here is how it runs end to end. A POST webhook at the path timersyncro receives data that includes a call_id and start and end timestamps. The flow looks up that call_id in a Google Sheet with two columns named Call and Ticket. If the sheet returns a ticket number, the next step sends a POST request to Syncro to create a timer entry on that ticket. The timestamps are converted into ISO format so Syncro records the correct start and end times. If the sheet has no match, the path stops cleanly with no changes, which protects your data from bad entries.

Setup is simple. You only need a Google Sheet for mapping and your Syncro base URL and API key. Expect time entries to appear within seconds and cut manual logging from about 10 minutes per call to under a minute. This is useful for MSPs, help desks, and any team that maps phone calls to support tickets and wants clean, fast, and accurate time capture.

• POST webhook endpoint at the path timersyncro to receive call data
• Google Sheets lookup on column Call to find the matching Ticket number
• Conditional check that skips creating a timer when the ticket field is empty
• HTTP POST to Syncro to create a timer entry on the target ticket
• Automatic conversion of start and end times into ISO format
• Generic header authentication for secure Syncro API access

• Reduce manual work from 10 minutes to under 1 minute per call
• Automate up to 100 percent of matched call time entries
• Improve data quality by blocking entries with missing tickets
• Connect Google Sheets and Syncro without CSV exports
• Handle up to three times more calls with the same staff

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'll need accounts with Google Sheets and Syncro. See the Tools Required section above for links to create accounts with these services.
3. Prepare your Google Sheet: create two columns named Call and Ticket in columns A and B. Fill rows with the call_id values and the target ticket numbers.
4. Open the Google Sheets node in n8n and set the credential. If you do not have one, choose Create new credential and follow the prompts to connect your Google account.
5. In the Google Sheets node, set the Sheet ID, set Range to A:B, set Lookup Column to Call, and keep Operation as Lookup.
6. Open the EnvVariables node and set the syncro_baseurl value to your Syncro base URL, for example https://yourtenant.syncromsp.com.
7. Open the HTTP Request node for Syncro. In the credential field, select Create new credential, choose HTTP Header Auth, and add your Syncro API key in the header value. Name the credential clearly, such as Syncro API Key.
8. Confirm the HTTP Request node method is POST and the URL uses the ticket number in the path tickets/{{Ticket}}/timer_entry. The body should include start_at and end_at fields.
9. Open the Webhook node and note the production URL. For testing, use the Test URL. Configure your source system to POST JSON with call_id, date_started, and date_ended in milliseconds to this URL.
10. Run a test POST. In n8n, watch the execution map. If the sheet returns a ticket, the flow should reach the HTTP step. If no ticket is found, it should go to the NoOp step.
11. Check Syncro to confirm a new timer entry appears on the correct ticket. If you see a 401 error, verify the API key and base URL. If no match occurs, confirm the Call value in the sheet exactly matches the call_id sent.
12. After testing, switch the Webhook node to use the production URL in your source system and activate the workflow.
