Xero Id Custom Field
We have the Xero integration but before that I had set up a custom field on the organisation record call Xero Id which I had started to populate with a value that would connect the Insightly record to Xero. (This process is now redundant as the integration does this for me).
When I go to the custom fields in settings I can see the organisation custom field Xero Id that I set up but under contacts I can also see a Xero Id that I don't remember setting up.
When I go to advanced reporting I can see the organisation custom field there and can search for the values that I had entered. Under the contact reports I cannot see a Xero Id custom field.
What I am wondering if whether or not Insightly uses either or these two custom fields to link records to gether or is there some other mechanism? It is really strange that I can see a contact custom field of Xero Id in the settings but nowhere else.
I don't want to delete either of them until I am assured it is not going to mess up my integration.
