How to change/update the profile of a User in Salesforce from apex code

It's my first blog writing, so ignore all the grammatical errors here :)

A user profile update is not allowed through apex code generally and it through error FIELD_INTEGRITY_EXCEPTION, Cannot change profile for current user: Profile ID.

It can be achieve by Http callout. How to do this, its pretty simple. There are 2 way to do this:

1st: If we have community or a site enabled in our sf org. It's  3-4 step process.

• Create a visualforce page and assign a controller to it. Make this page public through guest user permissions.
• Define an action in apex:page tag.  which will be called when ever this page executes
• In controller : action: write the code to update the profileId. It works.

1 2 3 4 5 6 7 8 9 10

public void callPublicSite(){ String remoteURL = 'https://testing.force.com/ProfileUpdate?userId=' userId+'&profileId='+profileIdToUpdate; HttpRequest httpRequest = new HttpRequest(); httpRequest.setMethod('GET'); httpRequest.setEndpoint(remoteURL); HttpResponse httpResponse = new Http().send(httpRequest); }

Here "ProfileUpdate" is the public page . which is executes , whenever callPublicSite method is called. Hence result , it do the Http callout and execute public page with given parameters.

Page Controller

1 2 3 4 5 6 7 8 9 10 11 12 13

public void doProfileUpdate() { try { String userId = ApexPages.currentPage().getParameters().get('userId'); String profileId = ApexPages.currentPage().getParameters().get('profileId'); update new User(Id=userId,ProfileId = profileId); } Catch(Exception e) { System.debug('::::user profile not update'+e); } }

Page Code

1 2	<apex:page controller="ProfileUpdateController" action="{!doProfileUpdate}"> </apex:page>

2nd way to do this :  If the sf org don't have enabled site or community, then we have to make a http callout to restful class.

Note : Remote URL use like this if namespace is enabled in org:
String remoteURL = 'https://na34.salesforce.com/services/apexrest/namespace/ProfileUpdate?_HttpMethod=PATCH';

Http callout code
don't mix the "selectProfile" method in restful class. keep where you want to execute your business logic.
For Current user this solution won't work.

1 2 3 4 5 6 7 8 9 10 11

public void selectProfile(){ String remoteURL = 'https://na34.salesforce.com/services/apexrest/namespaceHereifAvailable/ProfileUpdate?_HttpMethod=PATCH'; String userId = '005e877812882' //userid HTTPRequest httpRequest = new HTTPRequest(); httpRequest.setMethod('POST'); httpRequest.setHeader('Authorization', 'OAuth '+UserInfo.getSessionId()); httpRequest.setHeader('Content-Type', 'application/json'); httpRequest.setBody('{"userId":"'+userId+'","profileId":"'+commProfileId+'"}'); httpRequest.setEndpoint(remoteURL); HTTPResponse res = new Http().send(httpRequest); System.debug('BODY: '+res.getBody()); System.debug('STATUS:'+res.getStatus()); System.debug('STATUS_CODE:'+res.getStatusCode()); return null; }

Restful apex class code

1 2 3 4 5 6 7 8 9 10 11 12

@RestResource(urlMapping='/ProfileUpdate/*') global with sharing class ProfileUpdate { @HttpPatch global static String updateProfile(String profileId, String userId) { update new User(Id=userId,ProfileId = profileId); return 'Profile Updated'; } }

This all is done because when callout is responded , it do all action with admin profile.


Let me know , if it helped you or if you have any question regarding this.
