Customer context: The customer would like to use specific API endpoints from both v1 and v3 versions and is curious about the discrepancy in available endpoints between the versions.
Customer: Why are some API endpoints available in API v1 but not in v3 and vice versa?
Answer: API v1 is deprecated, meaning no new endpoints will be added to it. On the other hand, API v3 is a newer version still under development, so enhancements and new endpoints are being added continuously. You have the ability to use both v1 and v3 simultaneously.
