Hi Guys,
I’m going to show you how to connect Google blogger API using python. I had a requirement of creating more than 100 plus blog pages by duplicating the existing blog page. Below is the below breakdown:
- Retrieving the blog page from blogger
- Extract and copy the content from the blog page
- Create a new blog page and insert the extracted content
The main reason for posting this article, I couldn't find the right tutorial that can help in understanding the code in one go and it took a lot of time to accomplish this task. I hope this tutorial will help you.
There are two ways, you can interact with your blog using python:
In this blog, I will show how we can interact with blogger API using python with Oauth 2.0. It is a recommended way to interact with your Google API resources. The first step will be creating project and credentials
In order to access your enabled APIs(i.e, Blogger API in our case), we need to create credentials, these credentials must be kept in secret and otherwise, someone may steal your keys, you will end up paying for Google once the quota is exceeded. Please follow the below steps to create credentials for your project. Steps are in the below, video you can use it for creating client_secret.json file.
- Open the Google API Console Credentials page.
- Click Select a project, then NEW PROJECT, and enter a name for the project, and optionally, edit the provided Project ID. Click Create.
- On the Credentials page, select Create credentials, then OAuth client ID.
- You may be prompted to set a product name on the Consent screen; if so, click Configure consent screen, supply the requested information, and click Save to return to the Credentials screen.
- Select Web Application for the Application Type. Follow the instructions to enter JavaScript origins, redirect URIs, or both.
- Click Create.
- On the page that appears, copy the client ID and client secret to your clipboard, as you will need them when you configure your client library.
After creating the project, you need to enable the Blogger API v3 in the Google API console. Please follow the below steps:
- Navigate to APIs & Services
- Search for Blogger API
- Enable it
Your client-secrets should look like below:
{"web":{"client_id":"814572920180-5lua2cehvonjidhjck5sql4gf2roavu5.apps.googleusercontent.com","project_id":"wordpress-learning-203906","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://oauth2.googleapis.com/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"R0B_Ayy6A-PBhRIJ5nhUmFOe","redirect_uris":["http://localhost:8090/"]}
Note, after downloading the client_secret.json file, make sure to change the name. The name should be renamed as client_secret.json and place it in the folder wherever your current project is. My project folder is "E:\blogger api\python-blogger"
Open the command prompt and run as an administrator, navigate to the project folder, mine is "E:\blogger api\python-blogger" and install below libraries:
- pip install --upgrade google-api-python-client
- pip install httplib2
- pip install oauth2client
After installing libraries, copy the below the code and save it in your project folder and save the file with .py extension,
import httplib2
from oauth2client.client import flow_from_clientsecrets
from oauth2client.file import Storage
from oauth2client.tools import run_flow
from googleapiclient import discovery
CLIENT_SECRET = 'client_secret.json'
SCOPE = 'https://www.googleapis.com/auth/blogger'
STORAGE = Storage('credentials.storage')
# Start the OAuth flow to retrieve credentials
def authorize_credentials():
# Fetch credentials from storage
credentials = STORAGE.get()
# If the credentials doesn't exist in the storage location then run the flow
if credentials is None or credentials.invalid:
flow = flow_from_clientsecrets(CLIENT_SECRET, scope=SCOPE)
http = httplib2.Http()
credentials = run_flow(flow, STORAGE, http=http)
return credentials
credentials = authorize_credentials()
print(credentials)
*Note: please take care of the indentation, if you have issues copying from here, you can check using here

After saving it, run the python program, then you will see a browser will ask to login into your Google account and request to grant the permission. Once you have accepted it. You should see the message authentication successful, message on the command prompt
Once the authentication is successful, credentials.storage file will be created in the project folder, please refer to the below screenshot.
Credentials.storage file contains all information required for authentication, which prevents the program from authenticating again every time we are running the program. This is one time set up.
Then, create a function as below:
def get_pages_from_jobs(blogId):
credentials = authorize_credentials()
http = credentials.authorize(httplib2.Http())
discoveryUrl = ('https://www.googleapis.com/blogger/')
service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)
*Note: please take care of the indentation, if you have issues copying from here, you can check using here
At the end of the program, we need to call the above function(below highlighted in red). After the function, the code should look like this:
import httplib2
from oauth2client.client import flow_from_clientsecrets
from oauth2client.file import Storage
from oauth2client.tools import run_flow
from googleapiclient import discovery
CLIENT_SECRET = 'client_secret.json'
SCOPE = 'https://www.googleapis.com/auth/blogger'
STORAGE = Storage('credentials.storage')
# Start the OAuth flow to retrieve credentials
def authorize_credentials():
# Fetch credentials from storage
credentials = STORAGE.get()
# If the credentials doesn't exist in the storage location then run the flow
if credentials is None or credentials.invalid:
flow = flow_from_clientsecrets(CLIENT_SECRET, scope=SCOPE)
http = httplib2.Http()
credentials = run_flow(flow, STORAGE, http=http)
return credentials
credentials = authorize_credentials()
print(credentials)
def get_pages_from_jobs(blogId):
credentials = authorize_credentials()
http = credentials.authorize(httplib2.Http())
discoveryUrl = ('https://www.googleapis.com/blogger/')
service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)
get_pages_from_jobs(xxxxxxx)
*Note: please take care of the indentation, if you have issues copying from here, you can check using here
After that, you can copy the below code, you can copy the respective code for corresponding actions:
1. For users
Add the below code(highlighted in yellow) just below service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)
users = service.users()
# Retrieve this user's profile information
thisuser = users.get(userId='self').execute()
print('This user\'s display name is: %s' % thisuser['displayName'])
*Note: please take care of the indentation, if you have issues copying from here, you can check using here
2. For Listing for blogs
For listing the blogs, we need to add the below code(highlighted in yellow) along with the above 1st action, just below print('This user\'s display name is: %s' % thisuser['displayName'])
blogs = service.blogs()
# Retrieve the list of Blogs this user has write privileges on
thisusersblogs = blogs.listByUser(userId='self').execute()
for blog in thisusersblogs['items']:
print('The blog named \'%s\' is at: %s' % (blog['name'], blog['url']))
3. For posts associated with specific users
For listing the blogs, we need to add the below code(highlighted in yellow) along with the above 1st, 2nd action, Add the below code(highlighted in yellow) just below print('The blog named \'%s\' is at: %s' % (blog['name'], blog['url']))
posts = service.posts()
# List the posts for each blog this user has
for blog in thisusersblogs['items']:
print('The posts for %s:' % blog['name'])
request = posts.list(blogId=blog['id'])
while request != None:
posts_doc = request.execute()
if 'items' in posts_doc and not (posts_doc['items'] is None):
for post in posts_doc['items']:
print(' %s (%s)' % (post['title'], post['url']))
request = posts.list_next(request, posts_doc)
*Note: please take care of the indentation, if you have issues copying from here, you can check using here
4. For getting a specific page using ID
This code independent of the above 1,2,3 actions, you can just the below code(highlighted in yellow) directly just below the service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)
page=service.pages()
onepage=page.get(blogId=’xxxxx’,pageId=’xxxxx’).execute()
print("this will show specific onepage", onepage)
*Note: please take care of the indentation, if you have issues copying from here, you can check using here
5.For creating multiple posts/pages(in drafts)
This code independent of the above 1,2,3 actions, you can just the below code(highlighted in yellow) directly just below the service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)
cities=['canada','singapore','germany','italy']
for item in cities:
title="title something"+item
payload={
"content": "<div dir=\"ltr\" style=\"text-align: left;\" trbidi=\"on\">\nEspeciallySports is a sports news portal aims at bringing the latest sports news for the fans that cover MMA, WWE, UFC, Cricket, Football, etc </div>\n",
"title": title
}
respost=page.insert(blogId='xxxx',body=payload,isDraft=True).execute() #publishing the new post
print("printing the page id:",respost['id'])
*Note: please take care of the indentation, if you have issues copying from here, you can check using here
6. For updating the existing post with ID
This code independent of the above 1,2,3 actions, you can just the below code(highlighted in yellow) directly just below the service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)
payload={
"content": "<div dir=\"ltr\" style=\"text-align: left;\" trbidi=\"on\">\nEspeciallySports is a sports news portal aims at bringing the latest sports news for the fans that cover MMA, WWE, UFC, Cricket, Football, etc </div>\n",
"title": title
}
respost=page.update(blogId=’xxxxxx’, pageId=’xxxxx’, body=payload, publish=True).execute() #updating the existing post/page
