How do I check whether I can pass the InstaLink fee to my client?

Check the fee options while preparing the payment request, before you share the link. If your current link-creation screen offers fee pass-on, review the client's total with that option enabled and confirm that it matches what you agreed with them. Do not add a second manual fee on top without checking the displayed total.

If you cannot see a fee pass-on option, ask Skydo Support whether it is available for your request. Do not assume an existing link can be changed after sharing, or that every fee or tax is covered by the same control. Ask for confirmation before telling the client that the amount shown is the final all-in amount or promising a particular net payout.
