Using the API on Multiple Domains
An API Key is unique for the subdomain of the page you embed the API into. You are welcome to register as many keys as you like.
- images can be sent to the API from any domain. image_url does not need to be the same as the domain your key is registered for.
- your callback routine uplink_url can be any domain (images can be saved anywhere you like)
Depending on the use, for distributed applications it may be easier to embed the API on one domain, and create custom code to send images and callback routine parameters appropriately.
