Blogger JSON Feed API - [Data Sheet]

blogger json feed apiYou have finally reached the stage where you can now easily create BlogSpot widgets and plugins using your blog feed. Blogger gadgets and templates are coded using Blogger JSON Feed API which provides you with enough information to extract any information from a blog's feed in JSON format. We have discussed the most detailed tutorial where you learnt the basics of parsing JSON in JavaScript. If you have followed all this tutorial series, you are ready to build your custom gadget and add it to either Blogger widget directory or add it to your client's sites. Today I will share a Data Sheet of all important JSON objects, arrays and elements that will help you easily locate important data using direct queries.

In programming all objects, elements or arrays have a relationship between each other that is managed in a tree like structure. Where there is a parent/Child or Master/slave or Tree/branch relationship or hierarchy. This is a standard approach to organize data so that it could easily be sorted, re-organized, easily located and updated. You blog feed is similarly written in both XML and JSON format, out of which the JSON is more easily accessible and prompt to browser requests.

Below I have listed the Data Sheet for all JSON variables found in Blogger JSON Feed which you can use for direct access to important info related to your blog. You can find anything you want. You can run queries like:

  • Find the number of total posts published so far
  • Find the total list of all Labels used in the blog
  • Find Blog Title and meta Description
  • Find when was the blog last updated
  • Find information related to blog admin and authors
  • Find Post Published date and time
  • Find labels used inside the post
  • Access Post Title, Thumbnails used and Content written
  • Find total count of comments published inside a post
  • Extract short summary from your post content
  • Extract YouTube thumbnails from within the post
  • Find when was the post last edited
  • Find who wrote the post
  • Much more...


  • Objects are denoted with curly braces i.e. { }  and arrays with square brackets i.e. [ ].
  • "i" refers to index number and "j" refers to sub-index number.

  1. Can I do guest posting for this website?

    1. Buddy we have stopped accepting guests posts since a year. We may allow it later this year when we feel we need help in posting

  2. media$thumbnail shows the first images only, is there a way to use the second image instead?

    Thanks for the detailed information!

    1. Hi Micha,

      media$thumbnail is an object and not an array so by mentioning an index [2] wont work. There is a easy work around which I already shared in this part of the series:

      Display Posts by Label with 3rd Party Images

      Simple replace this part of the code:

      ListImage = json.feed.entry[i].content.$t.match(/src=(.+?[\.jpg|\.gif|\.png]")/)[1]

      with this

      ListImage = json.feed.entry[i].content.$t.match(/src=(.+?[\.jpg|\.gif|\.png]")/)[2]

      What this code does that it will scan your entire post for images. It will pick all images from inside the post. You can then choose which image to display by mentioning the image index inside [*]

      Let me know if you needed more help. I am glad you are trying the code and actually trying to learn by implementing. :)

  4. Hey Mustafa, I wanted to know is there a way to know when was the blog last updated without getting rest huge data along in response. Though "max-result=1" helps but still "category" in response is huge and is responsible for large size of response. How to solve this issue.
