Can a method using @InvocableMethod have multiple input parameters ?

Arun Kumar 1141Arun Kumar 1141
Hi Saravana,

Yes, a method annotated with '@InvocableMethod' can have numerous input parameters required. The annotation '@InvocableMethod' is used for defining an approach that can be identified by a Flow or Process Builder, and the approach can accept numerous input parameters of various forms.

For example:
You can write an apex code to create Contact having 2 parameters, FirstName and LastName using @InvocableMethod.

If you find this answer helpful, please mark it as best.
Thank you.

In the below articles, it is mentioned we can have at most one input parameter. Which I interpret as maximum one input parameter only . Am I correct ?

InvocableMethod Annotation | Apex Developer Guide | Salesforce Developers (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_annotation_InvocableMethod.htm)

Inputs and Outputs
There can be at most one input parameter and its data type must be one of the following:
  • A list of a primitive data type or a list of lists of a primitive data type – the generic Object type isn’t supported.
  • A list of an sObject type or a list of lists of an sObject type.
  • A list of the generic sObject type (List<sObject>) or a list of lists of the generic sObject type (List<List<sObject>>).
  • A list of a user-defined type, containing variables of the supported types or user-defined Apex types, with the InvocableVariable annotation. Create a custom global or public Apex class to implement your data type, and make sure that your class contains at least one member variable with the invocable variable annotation.
