Hello Creators,
We will be deprecating the old purchasing endpoint for Creator Store assets on 10/23. Since we launched real-world currency (USD) pricing for Creator Store assets, we have disabled Robux purchasing through this endpoint and have replaced this with a newer API. This does not affect any other purchasing flows for other products on our platform. This API was not seeing that much traffic and is being replaced with the newer one below.
Old API
POST https://apis.roblox.com/creator-marketplace-purchasing-service/v1/products/{productId}/purchase
New API
POST https://apis.roblox.com/marketplace-fiat-service/v1/product/purchase
Please let us know if you have any questions or concerns.
