Google Sheet Update Api : Getting error [Request is missing required authentication credential]

问题

I am calling Google Sheet Update Request in Postman with following parameters:

Url:https://sheets.googleapis.com/v4/spreadsheets/SpreadSheetId/values/SheetName!A1:D5 Request Type : PUT
Headers : Authorization - MyAccessToken
Request Body :

Getting Response :

Note : For Updating into Spreadsheet, I follow these steps :

Create an application on Google Api Console using this link and then move to Credentials section. Click Create Credentials, then OAuth Client ID, Create Application type as Web Application. For now leave the Restrictions Section. Then Create. Now Application is created.
Add some project Name in the OAuth Consent Screen Tab
Now, Authorize the API using this link. In the right corner, open the Settings Icon. Select Use your own OAuth Credentials as true. Add the Client Id and Client secret from the Project on Google Api Console. Select the Scope as https://www.googleapis.com/auth/spreadsheets under the Google Sheet Api v4 in the dropdown, then Authorize the API.

If Get redirect_mismatch_uri. then Copy the redirect URI till the oathPlayground or before the prompt parameter and paste it into the Authorized Redirect URI under the restrictions Section of project in Google Api Console. Then Access Token will be generated,

Get Access Token. Copy this access token in the request which I defined earlier.

But Getting error. I am not able to figure out the problem. Thanks in Advance..

Since you already have a refresh token, you can retrieve access token using refresh token. As a sample, it shows a method of how to retrieve access token using refresh token by curl. The access token retrieved by refresh token has the expiration time. Please confirm it.

You can see the detail infomation here. https://developers.google.com/identity/protocols/OAuth2WebServer

Curl command :

curl -L \
  --data "refresh_token=### refresh token ###" \
  --data "client_id=### client id ###" \
  --data "client_secret=### client secret ###" \
  --data "grant_type=refresh_token" \
  https://www.googleapis.com/oauth2/v4/token

Result :

{
 "access_token": "### access token ###",
 "token_type": "Bearer",
 "expires_in": 3600
}

Below curl command is for retrieving the information of access token. If the expiration time of access token had been over, the response is {"error_description": "Invalid Value"}. If it's not, you can see a following response.

Retrieve information of access token :

curl -L \
 --data "access_token=### access token ###" \
https://www.googleapis.com/oauth2/v2/tokeninfo

Result :

{
 "issued_to": "#####",
 "audience": "#####",
 "scope": "#####",
 "expires_in": 1234,
 "access_type": "offline"
}

EDIT1

This sample code is for updating the range of sheet1!A1:C2 to [["test1","test2","test3"],["test4","test5","test6"]].

Sample code :

curl -L -X PUT \
-H "Authorization: Bearer ### access token ###" \
-H "Content-Type: application/json" \
-d '{"values":[["test1","test2","test3"],["test4","test5","test6"]]}' \
"https://sheets.googleapis.com/v4/spreadsheets/### spreadsheet ID ###/values/sheet1%21a1%3ac2?valueInputOption=USER_ENTERED"

Result :

{
  "spreadsheetId": "### spreadsheet ID ###",
  "updatedRange": "sheet1!A1:C2",
  "updatedRows": 2,
  "updatedColumns": 3,
  "updatedCells": 6
}
