To capture value from a database table in a select widget

Q&A
1

I need to load a list of data from an auxiliary table created in the database inside my select object. How can I do this using an API?

If you cannot store those data using the Business Data Model (BDM) feature of Bonita then I recommend to use the REST API extension SQL data source available as a community contribution to get the data from your database.

You can then call this REST API extension using a Bonita form variable initialize with a REST GET API call.
