Marketplace Service issue

[past cipher]

The rewards keep duplicating when spamming the buy button while only paying once. I tried adding rebound, but nothing worked.

it's lowkey hard to read it from there💀 but its cause inside ur you don't actually check if ur UpdateAsync errored or like whether the pcall succeeded or not

so even if the updateasync failed ur code still sees granted == true and returns puchase granted and since no purchase History was written it grants another reward

so

if setSuc and setErr and granted then
  return PurchaseGranted
else
  return NotProcessedYet
end

might fix it

it may also be safer to not have the user spam requests, I would have a like "pending" table of the players pending a request then update the table neccessary. @past cipher

oh

[umbral peak]

tell me if the script worked or smt

[past cipher]

It's my first time monitizating so I'm not good at it

[past cipher]

Okay, I'll try

[umbral peak]

nah its fine

[past cipher]

@umbral peak Still bugged, I used 10ms autocliker and gave me 3x the reward

That's weird lowkey, looking at the documentation, Roblox queues a separate purchase request on their backend which makes sence ofc

its possible you could have multiple pending receipts on the backend so they go in with the same Id basically

then the queued receipts callback ur stuff simultaneously

[past cipher]

I'll try to remake the code

[umbral peak]

yeah Id just have a pending list of players

pretty simple compared to actually understanding the service

[past cipher]

oh wait

I tried to debug and

oh nvm

[past cipher]

@umbral peak Yoooooo I figured it out

So it's not really duplicating

It's purchasing multiple times while granting the same reward

Also, thanks for trying to help!
