To start your self-/joint-assessment, you then need to choose the Accredited Host (AH) that you would like to use for your assessment and link to them on the Gateway. Also, when you want to share your verified data from the Gateway to another AH, you need to make the link.
To make the link, on the Gateway, click on "Accredited Hosts" in the menu of your Gateway facility profile.
In the list of Accredited Hosts, click on their name to go to the AH platform and register there. Note down your Gateway Facility ID, you will be asked to include it in your AH profile.
After registering, log back into the Gateway. You will see that, under the "Linked" header, the AH now appears as "Linked" to the Gateway.
