Have you successfully mapped into an inline list ?
Yes!
The next steps are:
Step 4
Put your new array in another table (where your Inline list will point out) using a Single Value column
Step 5
Create so many columns as parameters your API call has. In my case, I have 6 parameters. These columns must be Single Value type using your array column as main source (step 4) and its Row parameter must be pointing out some position (item) of your array.
If your JSON payload has the same schema/items always, that Row parameter can be a static number otherwise, you have to create some logic to retrieve the right array position and find the desired value (what I did).
I hope it helps you at least to know what to do.
Feliz noche!
