Saving the call to API

[turbofred69]

Hi all,

I need some information to built a report through an API call.

Calling the API works fine, but I've an additional challenge...

- The value returned by the API is either "unknown" or a date. Once the date is known, it no longer changes ==> So I need only one API call. It is useless to call the API again during later refresh.

- The API doesn't keep history over 2 months. The API reply is then back "unknown" ==> I need to record the date previously provided by the API to keep an history longer than 2 months

Any suggestions about how to do that? I've started to create a new table, but I can't figure out how to update this table with new API replies to keep them over time.

Any help appreciated of course!

Hi @turbofred69 ,

You can try to use data flow and incremental refresh to save historical data.
