You should not be doing that. You should use graphql to load a virtual terminal to build your tickets

Thanks for that Jessa,
Do you have any documentation About the graphql API.

Our current interface (barSTOCK Drink Exchange) however uses direct Access to the database and a script to update live Prices.

Thanks,
Stuart

If it’s for a stock type price changes why do you need to mess with account and ticket tables? Surely it’s just price changes?
Graph api has basic self documentation listing functions and variables and there are several topics on forum to get going.
It’s a big topic to tutorial everything so you need to use tutorial for basic starter then develop using the more basic documentation within it itself.

Hallo Jesse,
Just to update you. I have solved the issue via the ‘unconventional’ way. It works a treat.
I will however long-term deploy the API methodology,
Thanks for your pointers.

Stuart
