Understanding Invocable Apex methods can significantly enhance the flexibility and power of your Salesforce automations. These methods allow you to call complex Apex code from processes, flows, and even external applications. Here’s a breakdown of the 5 key areas you need to focus on:
1. Basics and Definition
– Invocable Apex Methods are marked with the @InvocableMethod annotation.
– They enable the execution of Apex from a flow, process, or REST call.
– Only static methods can be annotated as invocable.
2. Considerations for Design
– Design these methods to be bulk-safe to handle multiple records efficiently.
– They should have a global or public access modifier.
– Consider the context of use to maintain the flexibility of the method.
3. Parameters and Return Types
– Invocable methods accept a list of a specific class type as parameters.
– Only primitive data types, collections, typed sObjects, or a List of a class that implements the InvocableVariable interface are supported.
– Return values must be a List of a specific type, enabling bulk processing.
4. Use Cases and Integration
– Ideal for complex business logic that can’t be achieved through configuration.
– Can be called from Salesforce automation tools or external applications via REST.
– Enhances reusability of code across various Salesforce orgs and scenarios.
5. Best Practices
– Write unit tests to cover various scenarios and ensure your code is deployable.
– Keep the methods context-agnostic to maximize their utility.
– Document the purpose and usage of each Invocable Apex Method to aid future development and maintenance.
Embrace the power of Invocable Apex to make your Salesforce org more dynamic and integrated.
