  1. Create credentials in Azure (an 'app')
  2. Configure Business Central to accept a connection from Trelica
  3. Connect Trelica to Business Central

Collect the IDs from Azure

You need three IDs which you can copy from Azure:

  1. From the Certificates & secrets tab copy the Client Secret Value (not the Secret ID)mceclip0.png

    The Client secret value will only be available for you to copy for a short period of time. If you are unable to view or copy it, then just create new one.

  2. From the Overview tab copy the Application (client ID) and the Directory (tenant) IDmceclip2.png
