i want to send some LINK to a contract B from a contract A, and in the same function call a function in contract B, im using transferAndCall(address _to, uint _value, bytes _data) function in the LinkToken contract, my question is : what should i put in the _data parametre and if you can give an exemple on how to do it so it can be more apparent ?

If you're just transferring tokens I don't think you need to put anything in the data parameter.

The data parameter is only used to pass additional parameters to indicate what the intention of the transfer is if a contract allows transfers for multiple reasons.

  • what value should i put ? i can't let it empty
