How to design table to store the value without proper mapping

I am having below two table. T1_CATEGORIES table is preloaded with data and I know the categories name.

My application is going to Consume some API and in API will get the name in response which is not same as Table 1 categories name. Manually i know which name is mapped to T1_CATEGORIES name. e.g,

So from API i will get the autoloan and i want to insert that in to T2_SUBID_CATEGORIES table. I am facing issue how i will get the T1_CATEGORIES_ID from table T1. How can i map this so my T2_SUBID_CATEGORIES will contains the data as below,

Can you please help me to design this. I don't want to handle it in my java code. Any suggestion/approach must be apricated. Thanks
