Creating Remote Site Settings Dynamically

As remote site setting is essential for making callouts to external systems.
We can create remote site through apex code:

Steps:

1.      Add a metadataService class either through WSDL or you can use attached  file: metadataService.class

2.      Use below code:

public void createRemoteSiteSetting(){

    MetadataService.MetadataPort service = createService();

    MetadataService.RemoteSiteSetting remoteSiteSettings = new MetadataService.RemoteSiteSetting();

    remoteSiteSettings.fullName = ‘abc123';

    remoteSiteSettings.url = 'http://www.clrdp727.com';

    remoteSiteSettings.isActive=true;

    remoteSiteSettings.disableProtocolSecurity=false;

    service.createMetadata(new List<MetadataService.Metadata> { remoteSiteSettings });

}

// This method returns the metadata service, using this we can fire action to create the remote site settings.

public static MetadataService.MetadataPort createService()

{

    MetadataService.MetadataPort service1 = new MetadataService.MetadataPort();

    service1.SessionHeader = new MetadataService.SessionHeader_element();

    service1.SessionHeader.sessionId = UserInfo.getSessionId();

    return service1;

}
