To initiate a scheduled invoice generation, an Autolaunched Flow invoking the Invoice API invocable class should be created where the flow will be called in a Batch Job.
Here are the necessary steps to follow:
Create a new Autolaunched Flow (No Trigger).
Add a new input variable that will serve as the unique identifier for each record to process. This input variable is necessary for the Batch Job creation.
Click the New Resource button.
Provide the following details:
Resource Type = Variable
API Name = Desired API Name of the input variable
Data Type = Text
Available for input (under the Availability Outside the Flow) = TRUE
Add a Get Records element to retrieve the record where an invoice will be generated.
Make sure to provide the exact object of the record.
Filter the records to be processed based on the stored record in the input variable.
Add an Action element to invoke the Invoice API invocable class.
Filter by Type and select Apex Action
Find and select the Invoice API invocable class.
Note: This is a test setup on how to set up Invoice API in Schedule Flow
Note: The required batch size would be 60 only to prevent hitting a governor limit.
Set up Flow
Create a Schedule Trigger Flow
Set Schedule
Select Object (ex. Opportunity)
Drag Get Records to the screen and select Gateway Account as Object and map the ID to the Opportunity Gateway Account
· Drag Action to the Screen. Filter by Type and select Apex Action and select Invoice API as Action
· Configure the apex action to pass the following Opportunity’s details to the invocable variables:
· Gateway Account = Opportunity’s Gateway Account (custom field)
· Amount = Opportunity’s Amount
· Currency = Opportunity’s Currency
· Token = Opportunity’s Payment Source (custom field) → Token
· Relate Record To = Opportunity record ID
· Relate Record To - Field = custom lookup field under the Gateway Invoice object that looks up to the Opportunity object
· And Click Done
· And after that, your flow should look like these
