Co-ordinate Parameters from a feature service

[MattSully]

Dear all,

We have a few layers within our organisation.  One of which being the Rights of way layer.
What I need is the rest endpoint to have an url address to identify the following.

We need to passing the required centre co-ordinates in the URL.

What I need to have is the parameters to put on the end to link to the centre point of each right of way at a certain zoom level.

Do you have a specification for the URL parameters for this endpoint?

https://www.arcgis.com/apps/mapviewer/index.html?url=https://services-eu1.arcgis.com/nvL9EDc30lviBdl... This does not accept what I have put in.

This is the parameters of the last one which worked:

I would like know if I can put across any eastings and northings (I know that is a very UK orientated projection)
I have this as a URL at the moment.

I know I have lat long in there... Is this the right sort of parameters?

Ok this is the parameters I have put in place.  Doesn't seem to want the recognise 27700 at the BNG coordinate reference system we wish to use.  I am missing that part of it.

https://www.arcgis.com/apps/mapviewer/index.html?urls=https://services-eu1.arcgis.com/nvL9EDc30lviBd...

"centre=276075%2C138587%2C27700&level=20"  These are the parameters that I am struggling with.  If I have read this correctly it should work.

Right I think I have got what I need, looking at the various help documents, provided in the community and from tech support....  This is what I need.
