2. Invoke callout()

1. Overview

invokeCallout() is the legacy outbound callout method in Skyvva used to send data from Salesforce to external systems such as SAP or SAP PI via outbound interfaces.

This method belongs to the Interface API Version V2 architecture and is primarily designed for simple and synchronous outbound processing scenarios.

It is commonly used in SFDC to SAP PI (SFDC2SAPPI) integration where minimal processing logic is required.

2. Purpose

The main purpose of invokeCallout() is to:

Trigger outbound communication from Salesforce
Send a single record (or related child records) per request
Provide a lightweight integration mechanism
Support basic SAP PI integration flows

3. When to Use invokeCallout()

Use invokeCallout() when:

The integration does not use Message Type Template (IStructure)
A simple outbound call is required
Queueable or advanced processing is not required
Working with legacy SAP PI integration (SFDC2SAPPI adapter)

4. Limitations

invokeCallout() has the following limitations:

Does NOT support Message Type Template (IStructure)
Does NOT support Queueable processing
Does NOT support Batch processing
Limited to legacy V2 integration architecture

8. Parameters

invokeCallout() requires the following parameters:

Parameter	Description
Interface ID	The Skyvva Interface configuration ID
IDs	Salesforce record IDs to process
Mode	Execution mode (`SYNC`, `AUTO`, `FUTUR`, `BATCH`)

9. Sample Apex Script for invokeCallout()

List<Id> ids = new List<Id>();
for(Account a : [SELECT Id FROM Account]) {
    ids.add(a.Id);
}
IServices.invokeCallout('Interface_ID', ids, 'BATCH');

10. Processing Flow

11. Key Characteristics

Legacy V2 integration method
Simple outbound processing
Synchronous execution only (SYNC/AUTO)
Mainly used for SAP PI (SFDC2SAPPI) integrations
No support for modern message structures or async queueing

12. Summary

invokeCallout() is a legacy Skyvva outbound method designed for simple and direct integration scenarios.

It is best suited for:

SFDC2SAPPI-based SAP integrations
Simple synchronous outbound communication
Existing legacy systems that do not require modernization

13. Recommendation

Use invokeCallout() only for legacy or existing integrations
For new implementations, consider invokeCalloutV3() for better scalability, adapter support, and message flexibility
