Amnon kruvi - Across the industry, admins and developers suffer from lack of cooperation without even realizing it. Developers see declarative tools as too weak to accomplish requirements, whereas admins see code as too complex to support. The result is separation and lack of cooperation. It doesn’t have to be that way. In this session, we’ll learn how to extend declarative automation tools using code and a feature called Invocable Methods. Using these methods, we can create new options that will be available to administrators inside Process Builder and Flow, reduce our use of triggers, and allow greater visibility for system administrators into how their system works. All of this results in less demand for support, less maintenance, and more time to do what we love and develop! Does the title mention something about music? That must be some sort of mistake – surely there is no way to present such a topic in song. That would be silly.

• Can tackle complex requirements
• Fine control over performance
• Easier than declarative tools
Advantages of Coding

9. #YeurDreamin2019
• Takes weeks to deploy new features
• Change requests require new cycle
• Code is less visible to declarative administrators

14. #YeurDreamin2019

15. #YeurDreamin2019
• Can be called from process builder or flow
• Must be static, and public/global
• Method annotated with:
@InvocableMethod(Label=‘My Method’ Description=‘Description’)
Invocable Methods

16. #YeurDreamin2019
• Can take one parameter, which must be List<>
• Can accept a list of a custom class for more inputs
• Class members annotated as:
@InvocableVariable(Label=‘My Parameter’ Required=false)
Input Parameters

17. #YeurDreamin2019
• Can return a List<> of results, matching input index
• Values become flow output options
• Return values can’t be used in a process

21. Performance on par with triggers for operations
up to 200 records.
Beyond that, processes/flows start to choke.

22. Invocable methods can not run in all contexts
triggers can:
So only use for things you would normally put in an after trigger.
