Help in programming for Power BI Desktop

Greeting,

I'm a new & beginner programer.

I'd like to know if there is a programming guide I can refer to, to develop tools for Power BI Desktop.

I'm planning to develop a Windows progam to:

• update an excel sheet
• open Power BI desktop
• do refresh
• maybe apply some filters
• export PDF
• save the file
• upload the .pbix file to some internet page & Power BI Report server.

Is there any guide/instructions I can refer to for building my program?

Thanks,

Hussain
