IM1 Pairing integration

Pairing integration is the process that allows suppliers to integrate their system with any principal clinical system through an interface mechanism.

The Future of IM1

There are no current plans to decommission IM1. The long-term future is being considered and, in the future, there may be alternative options which replace IM1. There are no confirmed plans or timescales for this currently. 

NHS Digital will provide further updates if this changes. For more information please contact: [email protected].

Interface mechanisms enable separate systems to:

  • read patient information
  • extract information in bulk
  • enter data into the other system

You can find more information about each of the IM1 interfaces by downloading a copy of the interface mechanism fact sheet.

There are three existing suppliers, who providing the Foundation Solution set to meet the Foundation Capabilities on the Digital Care Services Framework, they each offer interfaces for consuming systems to integrate with, Cegedim (Vision), EMIS (EMIS Web) and TPP (SystmOne).

There are also several new suppliers who will provide the foundation set capabilities once they have completed the onboarding process for the Digital Care Services Framework.  

Each supplier of foundation capabilities must provide an 'interface mechanism' for use by 3rd party systems to support integration between the core providing systems and specialist applications, such as clinical decision,  support, patient facing services, document management or appointments.

Interface mechanisms enable separate systems to: 

  • read patient information
  • extract information in bulk
  • enter data into the other system

The interface mechanisms for the provider suppliers offer under the digital care services framework must comply with the IM1 - Interface Mechanism - GP IT Futures Capabilities & Standards - Confluence (

Any consuming supplier can apply to 'pair' their service with any provider supplier system.  


Complete the IM1 Clinical and Information Governance prerequisites form IM1 prerequisites form - NHS Digital.

Supplier Conformance Assessment List (SCAL) will be issued if prerequisites are confirmed and in place as part of the application process. Your application will be assessed for compatibility against the provider suppliers' APIs and you will need to include some information about the product you are wanting to develop. We may also ask you to submit evidence to show you meet the SCAL requirements. 

When we have confirmed your product is compatible, you will be asked to execute a Model Interface Licence with each of the provider suppliers, this will cover your use of the provider suppliers' APIs. Once the Model Interface Licence has been executed by both consumer and provider suppliers, you will be given access to a test environment so you can develop your solution using the provider supplier guidance/documentation.
