Can you add this to links also? they also have a UISP ID

Does what you've done appear on sectors and APs also?

Can you give me an example of what a link's url looks like in UISP? Pulling up this link isn't working for me: https://db.mesh.nycmesh.net/admin/meshapi/link/609/change/?_changelist_filters=q%3D365

[Andrew-Dickinson]

Oh bummer you’re right I don’t think it supports deep-linking to links :(

[Andrew-Dickinson]

The best we could do would be to call the UISP API and describe the link and then hyperlink to one of the endpoints, but gross

I can make it work on sectors. I can also add it to access points, but I don't see any UISP IDs for them, at least in my copy of the DB.
