Which sentences are correct?
We don’t have to go there if we don’t want to.
or
We haven’t to go there if we don’t want to.
American or British English, the correct way to phrase this idea is:
We don't have to go there if we don't want to.
The other sentence
We haven't to go there if we don't want to [Wrong]
as far as expressing this particular idea of not having to go somewhere, is incorrect. Why? When have to/has to is negated, the result is don't have to/doesn't have to (do not have to/does not have to).
- You have to do this / You don't have to do this
- They have to go / They don't have to go
- He has to be there / He doesn't have to be there
haven't/hasn't (have not/has not) is used to express a lack of something:
- We haven't a clue.
- We have not a single vote.
- I haven't the faintest idea of his whereabouts.
- She hasn't the slightest hint of the answer.
I haven't got to go there would also be correct, although likely rarer.

In American English, at least, you would use the first construction:
We don’t have to go there if we don’t want to.
First of all, "correct" is not a very precise term in languages because they evolve constantly, and the definition of "correct" changes over time and depending on who you ask.
We don’t have to go there if we don’t want to.
This certainly sounds more natural than the other example. I would classify it as "nothing wrong with this one".
