You will have to extract it from the fields array. Its position in that array may vary depending on the tabs you have enabled, transaction type, and transaction content. This Guide is not exactly relevant, but may give you some ideas about positioning: https://www.manager.io/guides/17100.

No. Custom fields are defined only for a single transaction type.
