Calculate third-party shipping rates

[Keyurp]

I want to calculate Shipping rates using a third-party career API. I want to use my own. So it is possible now?

Also, I read the Shopify documentation and in this Shopify says that only an advance plan is allowed for third-party Shipping rates.

In the advance plan, I'm accessible to third-party shipping?

I want to use 'Mainfreight' to calculate the Shipping rates But only API is available.

So please provide your Feedback.

Did you have progress with this? It looks like the minimum requirement to activate CCS rates is to be on the Shopify plan and pay yearly.
