Hi All,
I'm new to ServiceNow and I do not possess any knowledge of coding.
I want to send an outbound REST message to Google Chat whenever a P1, P2, and P3 case is created.
I have followed the document https://docs.servicenow.com/bundle/rome-servicenow-platform/page/administer/integrationhub-store-spokes/task/setup-g-hangouts.html and created below,
From ServiceNow end,
Connection Alias, Credentials, Connection, System OAuth Application Registry. Enabled all the possible scopes under Application Registry/ OAuth Entity Scopes for testing purposes.
From Google End,
A New Project, Enabled and configured Google Chat API, Created a Service Account. Enabled all the possible scopes under App Registration.
Test Case,
Created an Action on Flow Designer with a REST API Get method to call https://chat.googleapis.com/v1/spaces for testing purposes to check the status of the connection.
Result,
Problem 01 - OAuth token releases but is only available for exact 60 minutes.
Problem 02 - REST Action Return an Error,
"error": { "code": 403, "message": "Request had insufficient authentication scopes.", "status": "PERMISSION_DENIED", "details": [ { "@type": "type.googleapis.com/google.rpc.ErrorInfo", "reason": "ACCESS_TOKEN_SCOPE_INSUFFICIENT", "domain": "googleapis.com", "metadata": { "service": "chat.googleapis.com", "method": "google.chat.v1.ChatService.ListSpaces"
I have tried all the possible solutions related to the error and still no luck.
Many thanks if someone can help.
Solved! Go to Solution.

Hi,
there is an issue in Google Chat API. This is not related to ServiceNow.
As you can read here: Google Chat REST API Docs you should define the OAUTH2 scope to "https://www.googleapis.com/auth/chat.bot
" but if you take a look at the oauth2 scope definitions for google OAuth 2.0 Scopes for Google APIs there is no scope for chat.
Solution
Use a Bot with a incomming webhook insted.
Create a Webhook in Google Chat and save the generated URL which looks like: https://chat.googleapis.com/v1/spaces/AAAAXXXXXX/messages?key=XXXXXXX&token=XXXXXXX
You can use a POST request to send a Card like this:
Create a Rest Message in ServiceNow
Add a Body:
{
"cards": [
{
"sections": [
{
"widgets": [
{
"keyValue": {
"topLabel": "${top_label}",
"content": "${content}",
"contentMultiline": "true",
"bottomLabel": "${bottom_label}",
"onClick": {
"openLink": {
"url": "${url}"
}
},
"icon": "${icon}",
"button": {
"textButton": {
"text": "${button_text}",
"onClick": {
"openLink": {
"url": "${button_url}"
}
}
}
}
}
}
]
}
]
}
]
}
Auto-generate variables and set some test values.
Now you can save and test it.
Create a FLOW Action
Create a Flow and use the Action

According to https://developers.google.com/chat/api/reference/rest/v1/spaces/list it looks like you need the "https://www.googleapis.com/auth/chat.bot" scope added to you oauth profile.
Please confirm you've added specifically this scope.
And then, also selected it in the Profile
If helpful or correct, please indicate so!

Hi Mattias,
Yes. I have added both https://www.googleapis.com/auth/chat & https://www.googleapis.com/auth/chat.bot scopes and selected them on the profile as well.
But still no luck and even though this chat.bot scope is mentioned in google docs. It is not accepted as a valid scope in Google API console from the Google end.
Very much appreciate your support on this.
Thank you.

Hi
please check the page https://developers.google.com/identity/protocols/oauth2
There are really helpful hints to make your OAuth based authentication work. Also the the topic "scopes" is covered there.
Kind regards
Maik

Hi Maik,
Thank you for reaching out. I have followed the mentioned document and configured below steps.
OAuth configuration is complete by following this doc from ServiceNow.
https://docs.servicenow.com/bundle/rome-servicenow-platform/page/administer/integrationhub-store-spokes/task/setup-g-hangouts.html
As per the shared page by you, I was managed to create a OAuth 2.0 Client ID and a Service Account as well.
But as I mentioned in my initial email "Insufficient Scopes" error with Method failed: (/v1/spaces) with code: 401 - Invalid username/password combo is all i have as the result.
I was wondering whether i have to follow the service account with JWT key for this? I do not know.
So far OAuth 2.0 Client ID/ Secret configured token fails to get the job done.
Thanks.
