+# google-sheets-remote-schema
+
+[Google Sheets API](https://developers.google.com/sheets/api/) is a service to read, write and format data in sheets programatically.
+
+## Adding Google Sheets as Remote Schema
+
+To be able to query Google Sheets data via Hasura, it needs to be added as a Remote Schema using the Hasura Console.
+
+- Get the Google Sheets API Key by visting the [Authorize Requests Sheets API](https://developers.google.com/sheets/api/guides/authorizing#APIKey) page.
+- Set the API key as `GOOGLE_SHEETS_API_KEY` environment variable.
+- We need to input the spreadsheet id from where we are going to fetch data. Set that as `SPREADSHEET_ID` environment variable. We can find the sheet ID in the url.
+- This custom resolver is used to accept a user's email and will return a filtered list of data pertaining to that user.
