Afternoon Hendry,
If I understand you correctly, you would like Create to navigate to a URL on a scheduled basis that will retrieve a file which then subsequently needs to be imported into Create.
Is the url consistent and the file I presume has the latest data during each fetch?
Are there any credentials needed?
If the file is public without any credentials required this should be feasible but only with a custom event action to perform the curl call on a signal and upload the file to a file object after which a new record event could fire an import action against said file.
Please let me know the answer to the questions above and I’ll do my best to point you in the right direction as far as an event action is concerned if appropriate.
