Accept MM2 as a payment or payout option for your business.
One API to let your users pay you in Murder Mystery 2 items — or get paid out in them. We hold the stock, run the bots, and handle delivery in game. You never touch inventory.
Every request is reviewed by hand, usually within two business days.
What sits behind the API
Automated bot fleet
Our own Roblox accounts hold and move every item.
Full MM2 catalogue
Knives, guns, pets and bundles, priced off live market data.
In-game delivery
Trades are executed by us, start to finish.
Named support contact
Partners get a direct line, not a queue.
How the integration works
Three calls either way. The mechanics are the same ones that run our own marketplace.
Call the payout API
Send the Roblox username of the person receiving items and what they should get, with an idempotency key so retries are free.
We reserve stock and assign a bot
The response tells you the payout is queued and names the bot holding it. Nothing settles until the items actually move.
Your user collects in game
They join that bot and accept the trade. We confirm delivery back to you once it has completed.
Read this before you design your flow. These are constraints of Roblox and of MM2, not of our API.
- Delivery is pull-based, not push
- Roblox will not let anyone hand items to a player who is not there. Our API tells you an item is reserved and which bot holds it — your user still has to join and accept the trade. We never report delivered until it has been.
- Item copies are fungible
- We guarantee the item type, not one particular copy. If the copy we listed is busy elsewhere, an identical one takes its place.
- Large payouts arrive in several trades
- Roblox caps how much can move in one trade, so a big payout is delivered as a sequence rather than in one window.
- A payout waits rather than fails
- We never refuse a payout because a copy is sitting on the wrong bot. It queues, and the API tells you who is holding it.
