Assurance process for APIs and services
Find out how to get assured for an API or service before your software goes live.
Overview
To use NHS APIs and services, your organisation must complete our assurance process and have your software approved by us before it can go live. This assurance process covers key areas such as regulations, security, clinical safety, technical standards, and information governance.
Although the assurance process will differ depending on your requirements, the information on this page will help you plan ahead for the main steps.
Our assurance process
We offer online and offline routes for assurance. The requirements are the same for all APIs and services. We intend to move to the online process for everyone, but for now you will be assured using one of the following.
- Online route: Digital assurance process for APIs and services
You can access the application via desktop or mobile, save progress, and complete it at your own pace. If the API or service you want to use is listed as assured through the Digital Onboarding Service, you must use this route. - Offline route: Supplier Conformance Assessment List (SCAL)
This is our offline, Excel-based route. If the API or service you want to use is not listed for the Digital Onboarding Service, you must use the SCAL process.
To find out about assurance for a particular API, read its API specification in our API and integration catalogue.
