blockchain – Understanding the configuration of the iquidus API

I am trying to understand what values ​​they ask me in the configuration. They are to install the block browser for Iquidus. I know how to get the Genesis block, since I have rigidly encoded it when I made a fork to create a new altcoin, however, I'm not sure how to get the genesis_tx. I know you can convert it from the Genesis block but I'm not sure how.

"genesis": {
"genesis_tx": "",
"genesis_block": ""}

As for the configuration of the API, they request an address, blocking index, blockhash and txhash. The blocking index can be any value within the height of your block … so I choose any value for the index with the corresponding address in the transaction list? Also, how do I get the txhash and the blockhash? In my opinion, these values ​​are subject to change and I know they are stored in the chain of blocks … Does anyone know how I can retrieve this information?

"api": {
"blockindex": "",
"blockhash": "",
"txhash": "",
"address": ""
}

I appreciate your time and consideration.
