I am trying to pay for the PDF API service as I have reached the end of the free quota but there is no way to do it - the "Learn More" link about quotas https://www.adobe.com/go/devs_quota returns 404 and there is not option to subscribe from the current integration.
How is this to happen? Do I have to create a new project and integration?
yeah. how to make payment?
Apologies for the delay in response.
