Vlocity Facts #24| Calling an Integration Procedure from Salesforce Flows

 We can call Integration Procedure from Salesforce Flows

we can use Integration procedure[IP] for complex requirements like for call outs, record creation or deletion, looping between records and performing Aggregative functions with out using Apex. 

Either we can use Apex class to call IP or In Flexcards, Omniscripts. But we can't call IP when ever any event happens on record to handle this we can use salesforce flows [record trigger flow or screen flow] to call Integration procedure.

Scenario: When amount >= 1000 we need to execute some set of steps like callouts or updating related records by using record trigger flow we can trigger IP.

1. Apex Class: 

global with sharing class IntegrationProcedureInvocable {
@InvocableMethod(label = 'Integration Procedure')
global static List < IntegrationProcedureOutput > runIntegrationServiceInvocable(List < IntegrationProcedureInput > input) {
System.debug(LoggingLevel.Error, JSON.serialize(input));
IntegrationProcedureOutput result = new IntegrationProcedureOutput();
result.output = JSON.serialize(
namespace.IntegrationProcedureService.runIntegrationService(
input[0].procedureAPIName,
new Map < String, Object >
 {
 'Id' => input[0].input
},
new Map < String, Object > ()));
System.debug(LoggingLevel.Error, JSON.serialize(result));
return new List < IntegrationProcedureOutput >
{
 result
};}
global class IntegrationProcedureInput
{
@InvocableVariable(label = 'Procedure Name') global String procedureAPIName;
@InvocableVariable(label = 'Input') global String input;
}
global class IntegrationProcedureOutput
{
@InvocableVariable(label = 'Output') global String output;
}}

When calling IntegrationProcedureService.runIntegrationService, be sure to replace the namespace with omnistudio, vlocity_cmt, vlocity_ins, or vlocity_ps.

Input Settings

Procedure Name: Specify the Integration Procedure to be run using this format: Type_SubType (note the underscore).

Input: For each input variable required by the Integration Procedure, choose Variable and specify the name of the input variable using the following format: {!variableName}

Output Settings: For each variable that is returned by the Integration Procedure, choose Variable and specify the name of the output variable using the following format: {!variableName}

2. Salesforce Record Trigger Flow

 Create record trigger flow on opportunity with condition when Amount >= 1000

Now drag and drop one apex action in that select the apex class what you have created by using above code and configure like this.

After that activate the flow.

Vlocity Facts #01 | OmniStudio DataRaptors

DataRaptor is a mapping tool that  you can use to read, transform, and write Salesforce data. For Example. In each interaction with a digital customer  or business process, the system needs to extract the data in order to display it. If the user modifies this data or enters new data, they also need to be saved. This is where we use OmniStudio DataRaptors.  Where to use DataRaptors? Retrieving Data:   OmniScript calls  DataRaptor Extract (via the integration procedure) to read the data from Salesforce. For example, OmniScript editing an account should display data such as account name, phone number, website, and so on. Manipulating data: OmniScript captures modified and new data based on user input. For example, an agent changes the  phone number of an account. Save Data:   OmniScript calls DataRaptor Load (via the integration procedure) to write the data back to Salesforce. For example, the updated account phone number is saved back to the Account rec...

Vlocity Facts #34 || Getting the details from the URL in a FlexCard and an Omniscript

Image
 1.The parameters in the URL must be in the format c__Node, followed by their values, in order to extract the parameters from the URL. For example: If you need to show different layout or different set of actions for community users and salesforces users you can pass different parameters in URL. For Community Portal Pass Community or any other reference value in ' c__Type '. https://salesforce.lightning.force.com/lightning/cmp/ omnistudio__vlocityLWCOmniWrapper?c__target=c%3ApHXTestFlexCard&c__tabIcon=custom%3Acustom18& c__Type =Community  For Salesforce Users Pass Salesforce or any other reference value in ' c__Type '. https://salesforce.lightning.force.com/lightning/cmp/ omnistudio__vlocityLWCOmniWrapper?c__target=c%3ApHXTestFlexCard&c__tabIcon=custom%3Acustom18& c__Type =Salesforce  2. We can get the value as {Params.c__Parameter} from the FlexCard and we can execute different actions based on the input. 3. From the omniscript,  we can retrieve ...

Vlocity Facts #44 || Communication between Omniscript and Flexcard [Pub/Sub]

Image
Flexcards have the ability to trigger and listen to two kinds of events: Custom and Pubsub events . Custom Events: Facilitate the transmission of information between a child and its parent. This can occur between a child Flexcard and its parent Flexcard, or between an element and the Flexcard to which it belongs. Pubsub Events: Allows communication between two separate components. This could occur between two separate Flexcards on the same Lightning page, known as sibling Flexcards, or between a Flexcard and an Omniscript.  In this post I will discuss about Pub/Sub event. Consider we have omniscript and flexcard individually on home page when an update happens we need to show those details in flexcard. To achieve this we can use pub/sub event. Step 1: Create a omniscript according to your requirement. I'm trying to create Contact record by using Step element and data raptor post action. Now to trigger the flexcard we need to configure the messaging frame work when an update happen...
