Yes, I was going to use the payment_id as a way of determining that the deposit was coming in from a particular source for my own internal purposes…
for instance the transactions I sent to the wallet had a payment id of ‘8ecd5245376247516adce5545b629a9ee85f3eaf84976e0855b9931c245857cb’
I would know the source was from an automatic payment from the mining pool.
I wanted to be able to query those specific transactions (with the payment_id) and run code based on those deposit transactions.
