I can't find how to filter jetton transactions from tonweb.getTransactions(address,limit). Does anyone worked on this part and know how to filter Ton only transactions ?

use tonapi

This examples show how to process specific coins by checking their balances. My issue is that i don't want to accept any kind of jettons at the momet / only toncoins accepted / when i am getting all transactions using tonweb ( toncenter api provider ) i don't see any fields that will tell me that the transfer is jetton.

Maybe i really have to switch to tonapi. But don't know if tonweb supports tonapi.

try Tonpay SDK then. You'll be able to enforce the currency of the invoice, and only TON (in your case) will be accepted

not the case for me. It's another payment system so it won't be accepted by my employers.

it'll save you (and your employers) a lot of time, but the choice is yours 🍊
