Connector deployment in zoho for third party integration

Connector deployment in zoho for third party integration

Hi Team,
I would like to create third party integration with zoho Desk and Want to deploy my code bases in Zoho any where.
Can you please confirm that is it possible to deploy custom code/script for third party integration to zoho environment.

I have tried with various options but not get any luck.
1. I had tried with extension but it is providing only UI extension not any backend job which can trigger every time and execute my custom script to sync the zoho desk with third party.
2. Checked for connection but looks like it is providing just API configuration not able to add any custom script or code.
3. Connector using sdk has this kind of facility but How can I deploy my script in zoho desk enviroment.

Any help will be really appreciable!!! Thanks
