This guide explains how to use the delete
method on the Message
resource of
the Google Chat API to delete a text or card message.
In the Chat API, a Chat message is represented by the
Message
resource.
While Chat users can only send messages that contain text,
Chat apps can use many other messaging features, including
displaying static or interactive user interfaces, collecting information from
users, and delivering messages privately. To learn more about messaging
features available for the Chat API, see the
Google Chat messages overview.
With app authentication, you can use this method to delete a message that the Chat app sent. With user authentication, you can use this method to delete a message that the authenticated user sent. If the user is a space manager for the space, you might also be able to delete a message that other space members sent. For more information, see Learn about your role as a Space Manager.
Prerequisites
Python
- A Business or Enterprise Google Workspace account with access to Google Chat.
- Set up your environment:
- Create a Google Cloud project.
- Configure the OAuth consent screen.
- Enable and configure the Google Chat API with a name, icon, and description for your Chat app.
-
Create OAuth client ID credentials for a desktop application. To run the sample in this
guide, save the credentials as a JSON file named
client_secrets.json
to your local directory.
- Choose an authorization scope that supports user authentication.
Delete a message with user authentication
To delete a message with user authentication, pass the following in your request:
- Specify the
chat.messages
authorization scope. - Call the
delete
method on theMessage
resource. - Set
name
to the resource name of the message to delete.
The following example deletes a message with user authentication:
Python
- In your working directory, create a file named
chat_message_delete_user.py
. Include the following code in
chat_message_delete_user.py
:from google_auth_oauthlib.flow import InstalledAppFlow from googleapiclient.discovery import build # Define your app's authorization scopes. # When modifying these scopes, delete the file token.json, if it exists. SCOPES = ["https://www.googleapis.com/auth/chat.messages"] def main(): ''' Authenticates with Chat API via user credentials, then deletes a message. ''' # Authenticate with Google Workspace # and get user authorization. flow = InstalledAppFlow.from_client_secrets_file( 'client_secrets.json', SCOPES) creds = flow.run_local_server() # Build a service endpoint for Chat API. chat = build('chat', 'v1', credentials=creds) # Use the service endpoint to call Chat API. result = chat.spaces().messages().delete( # The message to delete. # # Replace SPACE with a space name. # Obtain the space name from the spaces resource of Chat API, # or from a space's URL. # # Replace MESSAGE with a message name. # Obtain the message name from the response body returned # after creating a message asynchronously with Chat REST API. name = 'spaces/SPACE/messages/MESSAGE' ).execute() # Prints response to the Chat API call. # When deleting a message, the response body is empty. print(result) if __name__ == '__main__': main()
In the code, replace the following:
SPACE
: a space name, which you can obtain from thespaces.list
method in the Chat API, or from a space's URL.MESSAGE
: a message name, which you can obtain from the response body returned after creating a message asynchronously with the Chat API, or with the custom name assigned to the message at creation.
In your working directory, build and run the sample:
python3 chat_message_delete_user.py
If successful, the response body is empty, which indicates that the message is deleted.
Delete a message with app authentication
To delete a message with app authentication, pass the following in your request:
- Specify the
chat.bot
authorization scope. - Call the
delete
method on theMessage
resource. - Set
name
to the resource name of the message to delete.
The following example deletes a message with app authentication:
Python
- In your working directory, create a file named
chat_delete_message_app.py
. Include the following code in
chat_delete_message_app.py
:from google.oauth2 import service_account from apiclient.discovery import build # Specify required scopes. SCOPES = ['https://www.googleapis.com/auth/chat.bot'] # Specify service account details. CREDENTIALS = ( service_account.Credentials.from_service_account_file('credentials.json') .with_scopes(SCOPES) ) # Build the URI and authenticate with the service account. chat = build('chat', 'v1', credentials=CREDENTIALS) # Delete a Chat message. result = chat.spaces().messages().delete( # The message to delete. # # Replace SPACE with a space name. # Obtain the space name from the spaces resource of Chat API, # or from a space's URL. # # Replace MESSAGE with a message name. # Obtain the message name from the response body returned # after creating a message asynchronously with Chat REST API. name='spaces/SPACE/messages/MESSAGE' ).execute() # Print Chat API's response in your command line interface. # When deleting a message, the response body is empty. print(result)
In the code, replace the following:
SPACE
: thename
of the space where the message is posted, which you can obtain from thespaces.list
method in the Chat API, or from a space's URL.MESSAGE
: the message name, which you can obtain from the response body returned after creating a message asynchronously with the Chat API, or with the custom name assigned to the message at creation.
In your working directory, build and run the sample:
python3 chat_delete_message_app.py
If successful, the response body is empty, which indicates that the message is deleted.
