In an approach for an API key access authorization, a processor receives a transaction identity, a part of a token, and an API key identity attribute from a server. The transaction identity is generated in the server associated with generating the token. A processor receives a request from a client with the transaction identity for the part of the token. A processor looks up a transaction table via the transaction identity as an index. The transaction identity is associated with the part of the token and the API key identity attribute. A processor retrieves a client identity attribute through a second server via an IP address of the client. The second server registers the client. A processor matches a policy via the API key identity attribute and the client identity attribute. A processor sends the part of the token to the client.
