Method 1: Installation in the Google Analytics Code Box
The JivoChat code has the same criteria for placement as the code of Google Analytics, so can be placed in the same code box. This will not cause conflicts or disruption of your site in any way.
To install JivoChat on your site, go into your OpenCart admin panel, then navigate to Settings: System -> Settings.
Next, find your default template and click Edit.
Then, navigate to Server -> Google Analytics Code and paste the JivoChat code into the box. And you’re done!
The JivoChat code is available in the JivoChat admin panel, in the Installation section: Sites -> Settings -> Installation.
You can also reach the JivoChat code through this direct link: https://admin.jivosite.com/widgets/installcode/
Method 2: Installation with an ftp-client.
You can also connect JivoChat to your site through its source files, using an ftp-client.
Navigate to: Your site/catalog/view/theme/Your template/template/common/footer.tpl.
Open the footer.tpl file and paste the JivoChat code before the </body> tag.
Make sure to save the settings, and you’re done!
