Tebex commands help

I am looking for some help with Tebex. I have it installed on my server and its checking for commands but I can’t figure out the right command to use to give people money when they purchase a package. The command I am using to test is:

giveaccountmoney {hexid} bank 1000

If anyone knows what the issue is your help would be greatly appreciated. Thanks!

Check this How to monetize your fivem server
Did you follow everything stated in there? if yes, when you make a payment does it stay at “DUE”? if so, make sure to have latest version of fxserver AND to set the command to work only if player is online because you are using {hexid}
