  2. Go to
  3. Download the latest  ZohoEmbededAppSDK.min.js and save in the "lib" folder of your source code directory.
  4. Any file hosting server can be used to host the application.

    Note: An example of how the application can be hosted using Python server is given below:

    • Go to the website
    • Choose Windows x86 MSI Installer (2.7.6) (sig) to download.
    • Once Python is installed, run the server using the following steps:

    For Windows:

    1. Open Command Prompt and go to the location where you had downloaded and kept the unzipped source code for the embedded app.
    2. Start the Python server in HTTP mode with the following command
      • C:Python27/python.exe -m SimpleHTTPServer 8000

    For Mac:

    1. The python module already exists in the mac OS. So you need not download it again. Go to the location where you have saved the source code for the embedded app.
    2. Open up the Terminal and start Python by executing the following command
      • python -m SimpleHTTPServer 8000
    3. Execute http://localhost:8000 on the browser tab to verify the host from local machine.
