We will talk about how to call a Lightning Auto-launched flow from the Apex class in this blog post.<\/p>\n\n\n\n

The flow in Salesforce can be launched without user Interaction such as from a process builder or the apex code. So here we are creating a auto launched flow and call it through the apex code.<\/p>\n\n\n\n

Let\u2019s take a simple example to understand how to call a lightning flow from the apex.<\/p>\n\n\n\n

Example<\/strong><\/h1>\n\n\n\n

In this example, we are getting the value of Opportunity Stage name based on the opportunity id that we are passing from the apex code.<\/p>\n\n\n\n

Firstly, we have created lightning auto launched flow in which we have created two variables first is recordId<\/strong> and it is set as \u2018available for Input\u2019 <\/strong>and second is Opportunitystage<\/strong> which is used to send output to the apex class, and it is set as \u2018available for Output\u2019. <\/strong>Kindly refer below image.<\/p>\n\n\n\n

1.<\/strong> RecordId Variable<\/strong><\/h2>\n\n\n\n
\"RecordId<\/a><\/center>\n\n\n\n

2.<\/strong> Opportunity Stage Variable<\/strong><\/h2>\n\n\n\n
\"Opportunity<\/a><\/center>\n\n\n\n

Secondly, to get opportunity records we have added \u2018Get Records\u2019<\/strong> element in flow. Further more, we assign opportunity stageName field to the \u2018Opportunitystage\u2019<\/strong> variable as shown in below image.<\/p>\n\n\n\n

3. Get Opportunity Record<\/strong><\/h2>\n\n\n\n
\"Get<\/a><\/center>\n\n\n\n

4. Get Opportunity Record Filter<\/strong><\/h2>\n\n\n\n
\"Get<\/a><\/center>\n
Get Opportunity Record Filter<\/i><\/center><\/font>\n\n\n\n

For instance, to call flow from apex class, create an instance of an Interview object by using \u2018Flow.Interview.flowName\u2019<\/strong>. It uses start() method to execute your flow.<\/p>\n\n\n\n

5. Lightning Flow<\/strong><\/h2>\n\n\n\n
\"Lightning<\/a><\/center>\n\n\n\n

For example, refering to the apex class code below, you will notice we have created the instance of Interview object and passes opportunity Id as a parameter.<\/p>\n\n\n\n

\/\/Create parameter\nMap<String, Object> Params = new Map<String, Object>();\nParams.put('recordId','006p000000Aal2EAAR');\n\n\/\/create instance of Interview\nFlow.Interview.GetOpprtunityStageName stage = new Flow.Interview.GetOpprtunityStageName(Params);\n\n\/\/Invoke start method\nstage.start();\n\n\/\/get value from Flow\nstring stageName=(string)stage.getvariableValue('opprtunityStage');\nsystem.debug('stageName::: '+stageName);\n<\/code><\/pre>\n\n\n\n
As a result, after execution of flow it will return the stage of that particular opportunity which id we have passed as a parameter. kindly refer to the below image.<\/p>\n\n\n\n
6.<\/strong> Debug Result<\/strong><\/p>\n\n\n\n
\"Debug<\/a><\/center>\n\n\n\n
In conclusion, using the steps above you can call lightning auto launched flow from the apex code.<\/p>\n\n\n\n
