Hey @ovizii, I don’t think you are doing anything wrong here. I just gave this a go on my end and it seems the time parameter is added, but n8n continues to send the range parameters as well which seems to throw off the Wise API here.
I’ve raised a pull request to fix this problem here:
We’ll confirm once this has been merged.
In the meantime, you could use the range parameters to select a very short range only including a single result like so:
Now this will return the exchange rate at midnight UTC, but I hope that’s still close enough for your purposes. If not, you would need to either wait for the fix to be released or call the WISE API directly via the HTTP Request node.
Please accept my apologies for the inconvenience this might cause.
