Non of the plug-ins that are available support the brokers available in my country.
I plan to trade via different broker and different markets using APIs.
Is it possible to do it in Zorro? I don't want to invest time in develop and test a new plugin from scratch.
I can write a simple python tool which can call the APIs but that's pretty much it.
What are my options for the path of least resistance and good robustness.

Interactive Brokers and Finvasia are both available in India. Interactive Brokers in particular is recommended.

This is great. Thank you for the links. Follow up questions:
1- Would I be able to download historical data from them like how Zorro usually downloads from forex brokers?
2- Are IBKR and Finvasia available with Zorro Free version?

Read the manual first before posting questions.

Both questions are answered in the provided links. See https://zorro-project.com/manual/en/restrictions.htm for additional info about the Zorro licenses.

Will be great if there is Zorro integration with Zerodha as Zerodha is the largest and most technical savvy broker in India

You can pay oP Group to add it to Zorro:

Or develop it yourself:

Better yet, just use Interactive Brokers.
