Webhook Sync: Look Up & Sync External Data to Sheets
External systems (CRM, help desk, forms) have data that should sync to your Sheets. Notis webhook automations look up matching rows and sync data—keep records aligned without manual merges.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Look up spreadsheet row
Finds the first row in a google spreadsheet where a cell's entire content exactly matches the query string, searching within a specified a1 notation range or the first sheet by default.
Why this helps
Multiple systems hold overlapping data. Manual reconciliation is error-prone and constant.
- External data automatically synced to matching Sheets rows
- No manual data entry or reconciliation
- Records stay aligned across systems
- Single source of truth for all tool integrations
Setup
Build it in a few focused steps.
- 1Connect Google Sheets to Notis.
- 2Create a new automation: 'When an external service POSTs an update to my webhook, look up the matching row in my Sheets tracker (match on customer ID, email, or task ID) and sync the updated fields.'
- 3Tell Notis: The lookup criteria (which field to match on, e.g., customer_id). Which Sheets columns to update with external data.
- 4Generate your webhook URL. Share it with the external system's webhook settings.
- 5Select 'Notis Webhook' as the trigger.
- 6Pick a notification channel.
- 7Test by POSTing sample data to your webhook—the matching Sheets row should update.
Questions about this workflow
What if the external data doesn't match any row in Sheets?
Tell Notis to create a new row if no match is found. Or, only sync if a match exists—your preference.
Can I transform external data before syncing?
Yes. Tell Notis to map external field names to Sheets columns and apply any formatting rules (date formats, string transforms, etc.).
What if the external system sends conflicting data?
Notis will sync the latest data. Or, you can configure a rule to only sync if the external data is newer than the current Sheets value.

Supported Triggers and Actions
Notis builds workflows that link Asana to Google Sheets. A trigger fires from one place; an action lands in another.
Asana triggers
Google Sheets actions
Attachment Added to Task
Triggers when an attachment is added to a task.
Add Sheet to Spreadsheet
Adds a new sheet (worksheet) to a spreadsheet. use this tool to create a new tab within an existing google sheet, optionally specifying its title, index, size, and other properties.
New Comment on Task
Triggers when a comment is added to a task in a project.
Aggregate Column Data
Searches for rows where a specific column matches a value and performs mathematical operations on data from another column.
New Task Created
Triggers when a new task is created in a project.
Append Dimension
Tool to append new rows or columns to a sheet, increasing its size. use when you need to add empty rows or columns to an existing sheet.
Task Moved to Section
Triggers when a task is moved to a section in a project.
Batch get spreadsheet
Retrieves data from specified cell ranges in a google spreadsheet; ensure the spreadsheet has at least one worksheet and any explicitly referenced sheet names in ranges exist.
Tag Added to Task
Triggers when a tag is added to a task. Note: Asana's event structure is inverted for tag events — the resource is the task and the parent is the tag. So parent.gid gives the tag GID.
Batch update spreadsheet
Updates a specified range in a google sheet with given values, or appends them as new rows if `first cell location` is omitted; ensure the target sheet exists and the spreadsheet contains at least one worksheet.
Task Updated
Triggers when a task is updated in a project.
Batch Update Values by Data Filter
Tool to update values in ranges matching data filters. use when you need to update specific data in a google sheet based on criteria rather than fixed cell ranges.
Clear Basic Filter
Tool to clear the basic filter from a sheet. use when you need to remove an existing basic filter from a specific sheet within a google spreadsheet.
Clear spreadsheet values
Clears cell content (preserving formatting and notes) from a specified a1 notation range in a google spreadsheet; the range must correspond to an existing sheet and cells.
