At what level can I start doing heist?

I´m new player to path of exile and when I was checking all the different content players can do I got interested in heists. But I wasn´t able to find out when I can start doing this, do I need to go trough all the campaign, or is there minimum lever requirement or something like that? I am level 50 right now and I was just wondering if I´ll be able to check this out anytime soon or I need to level up much more.
I don´t have much experience with PoE so far so any info is appreciated, thanks!

You are high enough level to start heist. Just need rogue's markers to go to the harbor and some contracts to run.

Heist can be started as soon as you start act 6 (returning to Lionseye watch). This is roughly level 50, but milage may vary, and the game should force a heist contract in the first zone or two and introduce you to the mechanic.

However, you can't get super deep with it at that point, Grand Heists cannot be done prior to level 68 (or at least, the ability to open extra rooms and wings requires an ability to complete level 68 heists). In addition, prior to end game, you'll be forced to take really low rate encountering of smugglers caches in campaign zones, or moderately expensive maps from Whakano (or players, which tend to be cheap, but requires interacting with the market which is always a crapshot experience of afk or busy players, and many don't list low level contracts as it's often not worth their time to sell and likely will cost WAY more, as Chaos is often the lowest value players are willing to interact with).

Like most of the past content, I'd generally say you don't meaningfully interact with them until 68 where you can run maps and open up atlas passives to aim for the mechanic to be consistant.
