Hi @GaryP-AE
I don’t know if this is what you’re after but we announced a change to the Bills API endpoint in May and recently turned off the old version of the endpoint which may have affected some integrations.
We have sent several communications out to integrators we had in our records warning them of the change. It could be that some of those integrators haven’t been able to switch over yet.
You can read the full details of the change we’ve made in the thread linked above.
Hope that helps!
