If you’re a blogger, digital marketer, or developer looking to automate your Blogger (Blogspot) posts using the Blogger API, one of the key questions you must be asking is:

“How many posts can I publish daily or monthly via the Blogger API without hitting limits or restrictions?”

This article provides a complete A to Z guide explaining the Blogger API posting limits, quotas, best practices, how to monitor usage, and how to safely automate your blog posts.

What is Blogger API?

The Blogger API is a RESTful service offered by Google that allows developers to programmatically access and manage Blogger blogs. Using the API, you can create, update, delete, and retrieve blog posts and comments without manually using the Blogger web interface.

It’s widely used to automate tasks like bulk posting, content syndication, or integrating Blogger with other systems.

Why Automate Posting Using Blogger API?

  • Save time: Automate bulk blog publishing instead of manual work.

  • Consistency: Schedule and post content regularly without human error.

  • Scale: Manage multiple blogs or large amounts of content from a single program.

  • Integration: Connect Blogger with other platforms (CMS, social media, databases).

Blogger API Quotas and Limits: What You Need to Know

Google imposes limits to protect users and infrastructure. These limits control:

  • How many API calls you can make per day

  • How many posts you can publish in a given time

  • Rate limits to avoid spam and abuse

1. API Request Quotas

The Blogger API falls under Google Cloud's API management system. For most users, the default quota is:

  • 10,000 API requests per day per Google Cloud project (subject to change).

  • 100 requests per 100 seconds per user (rate limiting).

Every API call counts as one request. For example:

  • Creating a post = 1 request

  • Editing a post = 1 request

  • Deleting a post = 1 request

2. Daily and Monthly Post Limits

Technically, since one post creation is one API request, you could publish up to 10,000 posts per day if you only do posting through your API key.

But:

  • Google expects typical users to publish fewer posts.

  • Publishing hundreds or thousands daily might flag your account for suspicious activity.

  • There are practical limits due to rate limiting and account health.

Recommended safe posting volumes:

Time FrameRecommended Number of Posts
Daily20 - 50 posts
Monthly600 - 1500 posts

3. Rate Limiting and Backoff

You can’t send all requests at once because Google limits how many requests you can send per 100 seconds (usually 100 requests). To avoid hitting this:

  • Space out your posts over time.

  • Implement exponential backoff on errors (retry with increasing wait time).

  • Use batch processing carefully.

4. Account and Blog-Specific Limits

Google may apply stricter limits depending on:

  • Age of your Google account.

  • Blog’s reputation and past violation history.

  • Spam detection algorithms.

  • Content compliance with Google policies.

New or flagged accounts may have tighter limits or risk suspension if too many posts are made in a short time.

How to Monitor Your Blogger API Usage and Quotas?

  1. Google Cloud Console:
    Go to console.cloud.google.com > Select your project > APIs & Services > Dashboard.
    Here you can view your API usage and quota consumption.

  2. API Response Headers:
    Some API responses include quota remaining and reset time headers.

  3. Error Responses:

    • 403 Quota Exceeded means you hit a quota limit.

    • 429 Too Many Requests means you hit a rate limit.

Best Practices for Using Blogger API to Automate Posts

  • Start slow: Begin with a small number of posts per day to gauge limits.

  • Respect rate limits: Add delays between posts to avoid throttling.

  • Use exponential backoff: Automatically retry failed requests with increasing wait times.

  • Validate your content: Ensure your posts follow Google’s content policies to avoid flags.

  • Monitor your quota: Regularly check usage in Google Cloud Console.

  • Use OAuth 2.0 properly: Authenticate securely and refresh tokens as needed.

  • Log API errors and responses: Helps to debug and avoid repeated failures.

  • Batch your posts if possible: Group multiple API requests in batches (if supported) to optimize calls.

Step-by-Step: Automate Posting Using Blogger API

Step 1: Enable Blogger API and Create Credentials

  • Visit Google Cloud Console.

  • Create a new project.

  • Enable the Blogger API.

  • Create OAuth 2.0 client credentials.

Step 2: Authenticate

Use OAuth 2.0 to authenticate your application with the user’s Google account.

Step 3: Use the API to Post

Send POST requests to the endpoint:

bash
POST https://www.googleapis.com/blogger/v3/blogs/{blogId}/posts/

with JSON body containing the post content.

What Happens If You Hit the Limits?

  • Your API requests will start to fail with errors.

  • You may get temporary restrictions.

  • Google may flag your account for suspicious activity.

  • Worst case: Your blog or Google account might be suspended.

Always plan your automation to avoid hitting limits.

Real-World Use Cases of Blogger API Automation

  • News Aggregators: Automatically pull news from multiple sources and post on your blog.

  • Content Marketing: Schedule and publish hundreds of SEO-optimized posts.

  • E-commerce: Publish product updates, announcements, or reviews automatically.

  • Multi-blog Management: Manage content for many Blogger blogs from a central dashboard.

Final Thoughts

The Blogger API is a powerful tool to automate your blogging workflow, saving time and increasing productivity. While the theoretical limits are quite high, practical and policy-related constraints mean you should be cautious about how many posts you publish daily or monthly.

By following the guidelines above, monitoring your API usage, and respecting Google’s rules, you can automate your Blogger content successfully without risking your account or blog.
