When your project is deployed, invoke your function from Apex.
Make sure the current directory is your project root directory and use the following command to create an Apex class:
1sf apex generate class --name FunctionApex --output-dir force-app/main/default/classesIn VS Code from the Command Palette, choose SFDX: Create Apex class and enter the filename FunctionApex.
Tip
This command creates a FunctionApex.cls file with template code. Replace the contents of the file with the following Apex code:
1public with sharing class FunctionApex {
2 public static void test() {
3 System.debug('Invoking myfunction');
4
5 functions.Function myFunction = functions.Function.get('MyFunctionProject.myfunction');
6 functions.FunctionInvocation invocation = myFunction.invoke('{"name":"MyAccount"}');
7 String jsonResponse = invocation.getResponse();
8
9 System.debug('Response from myfunction ' + jsonResponse);
10 }
11}This class file invokes the function with a sample payload and prints the response.
Deploy your Apex code to your scratch org using the following command:
1sf project deploy start --target-org MyOrgAliasIn VS Code, from the Command Palette, choose SFDX: Push Source to Default Scratch Org.
Tip
Deploying your Apex code with sf project deploy start can cause the following error:

7force-app/main/default/classes/FunctionApex.cls Type is not visible: functions.Function (6:51)This error appears when the Apex class is running on API version 52.0 or earlier. To fix this issue, navigate to /force-app/main/default/classes/ and open the FunctionController.cls-meta.xml file. Edit the file to update the API version to 53.0 or later:
1<?xml version="1.0" encoding="UTF-8" ?>
2<ApexClass xmlns="http://soap.sforce.com/2006/04/metadata">
3 <apiVersion>53.0</apiVersion>
4 <status>Active</status>
5</ApexClass>Open the scratch org’s Developer Console to create a TraceFlag record. This record enables Apex debug logs in your scratch org and lets you execute apex log commands if needed.
1sf org open --path /_ui/common/apex/debug/ApexCSIPageNow, invoke your Apex code to execute your function:
Linux/OSX
1echo "FunctionApex.test();" | sf apex run --file /dev/stdinWindows
1echo "FunctionApex.test();" | sf apex runThe output looks something like this:
1Compiled successfully.
2Executed successfully.
