Importing large amounts of JSON data

[JB1]

Hi, when bringing in large amounts of JSON data via a REST API and updating back-end tables, what would be the preferred method? I have had issues in the past when trying to handle large amounts off data as variables in script. Thanks..

you can use here import set api to store those data into staging table and then map those data into your target table using transform map. . 

doc link for further details.

I forgot to mention that we are doing a GET from ServiceNow - the data is not being pushed into ServiceNow, so I do not think that the Import Set API is an option, unless I am mistaken..

Hi,

Are you consuming ServiceNow's GET endpoint in your external application?
