Does anyone have any insight into the differences between using the APIs provided by abr.gov.au and ASIC Connect (or are they the same thing behind the scenes perhaps)? i.e. of I want to validate business names, check ABNs etc which one should I be using, there seems to be a lot of overlap?
I recommend using the ABR API’s if they provide the data you require. For ABN registrations that is the source of truth.
Raw data also available (and regularly updated, but I would not assume as quickly as the API) from https://data.gov.au/dataset/ds-dga-5bd7fcab-e315-42cb-8daf-50b7efc2027e/details
