Good afternoon,
The Business Registry API specifications have been published. You can view them at https://bcregistry-demo.apigee.io/docs/businessproxy/1/overview.
In addition, there are postman collections available at https://developer.connect.gov.bc.ca/br/apigw-business-api-demo.postman_collection.json.zip.
The sandbox environment will be updated next week (between Aug 26 and Aug 30, 2024) with our latest code base to allow you to begin working and testing with our APIs.
David McKinnon
