Send historical events the last 90 days by api

I want to use orders data of stores as conversations event for recommend.
I search in document and found this Get started with click and conversion events | Algolia
Now there are two methods to send events

  • via api: this only allows events from the last four days
  • via csv upload: with this, I can upload events from the last 90 days but I have to upload file in browser

Question: how I can send events from last 90 days via api or is there a api to upload csv file ?

I asked the same question about a year before and now I want to know if there is any update about it!
Thank you!
