FAQ: How can I select another Xero tenant (account)?

Coupler.io allows choosing any tenant under the connected account to pull data from.

The drop-down has all tenants available under your account. All further configurations will be applied to the chosen tenant. 

Please note, that Coupler.io defines available tenants during the connection creation, so, if you add a new tenant and would like to use it also, then you have to reconnect the Xero account.
