Magento 2 Tier Price Auto-Incrementing Price ID

Currently I am generating new Tier Prices based on values i’m passing in. The Tier Price structure looks like this:

[     {         "price_id": "1",         "website_id": "0",         "all_groups": "0",         "cust_group": "1",         "price": "5.0000",         "price_qty": "1.0000",         "percentage_value": null,         "website_price": "5.0000"     } ] 

However, as you can see the price ID I have had to set as “1”. When doing this same process through the Magento Advanced Pricing an Auto-Incrementing ID number is attached to the Tier Price. I am looking for a way to get where that Auto-Incrementing number is and add it to my Tier Price.
