Thanks for reaching out to the Adobe Stock community.
I have licensed images already and I need to show proof that I have the proper license. I don't see anywhere in the order history to download a form that shows I have permission to use the images I have purchased.
We do not provide a separate proof for the licenses. The assets which are licensed are always displayed under the "license history tab".
Also, you can get the invoice for the purchases you have made. Please refer to Managing your Membership FAQ: How do I print a payment receipt or invoice to understand the workflow.
If you still face any troubles, feel free to update this thread.
I came here with the same question... the receipts you provide don't even have the proper number of the clips. How can I match up the invoices with each clip when they don't even reference the ID number?
