You can manually share a request with your client by sending them a link to it.
To be able to do that, activate Allow share via link without requiring login when you first publish the request. This is available in the last step (Finalize) of the request builder:
As soon as the request is published, you’ll see a new page with the Client Share Link that you can copy to your clipboard:
If you don’t copy and send the link to the client immediately, you can do it later through the Requests tab. Find your request and click the dotted area in the upper-right corner to see a drop-down menu with Share Settings:
Once there, a pop-up will appear with the Client Share Link that you can copy and manually send to your client.
