Thank you @Victor!
Do you think that would be possible to update a list with link previews using countdown and Custom Actions for websites URLs that are already in a database?
Well, in theory it is possible. However, this might be blocked by Linkpreview.net - if you send too many requests, you can get “429 Too many requests / rate limit exceeded”.
First, you have a limited number of requests per hour (see Linkpreview’s pricing policy).
Second, there might be a limitation for the number of requests / minute (I didn’t find the limitation in the docs, but it usually exists).
As upon countdown timer finish the timer will send a request for each record in the list, you might hit either one or another limit.
Best regards, Victor.
