We have been made aware through our another software provider that HMRC have made a minor change to security service XML api's on 22nd February to enhance security. Therefore we have been advised to make changes.

I wanted to know where IFS are with this and if there is any subsequent changes to be made in IFS system.

Can I please get a response urgently, as this could affect us from sending CIS submissions /Supplier Verifications to HMRC which are statutory requirements
