Verifying an API Key
If a print service provider has provided users of the printer driver with API keys, the Workflow
process that receives print jobs will need to verify the API key. This topic shows how to do that.
The API key in the HTTP headers
If the printer driver was configured with an APIkey, it will include the API key in its HTTP
headers as a bearer token when sending a print job. Bearer token authorization looks like this:
Authorization: Bearer «token»
where «token» will be the API key.
The Workflow process
The Workflow process will begin with a Server Input task.
In order to tell the printer driver if an API key is missing or incorrect, the Input task of the
process must be set to return a custom HTTP server response code, which is stored in a
variable (in this example: %{http_response}).
