Without an screen shot we cant help, but what i think at this stage is.

the API result return a list, and you can just saving the list.

what i suggest:

Make the api call as data. and then create API workflow, which take that data as input.

then when you call the api on next step call the API workflow on list, and pass the api call. on it.

and choose this api call as input.

inside the workflow create the job.
