Insert Custom Data to Custom post Taxonomy

Hello Guyz, Im using typeform and webhook to fetch data from typefrom to my wordpress site now i can fetch the data in a json format and decoded the data to normal array. Now i want to store that data to a custom post’s taxonomy. For example i have a post name vents and have 1 taxonomy contributor the taxonomy have 2 fields name and description also the typeform have 2 fields same as name and description. Once i fetch the data from typeform i have to store that data to my CPT taxonomy Programatically throgh code or function. I hope you guyz understand my question thanks
