Question: I have two platforms. Can I use one API key for my two platforms, or do I require two separate API keys?
Response: You may have multiple keys, or can use the same key, in as many services as you want. This is at your discretion. Note, you can periodically request a new key, roll over to that, and revoke your older key (effectively doing a key rotation). You may also wish to have a spare key available so if needed you could revoke the key in use and use the spare.
