Validation of New Relic License Key

Is there a way to verify the validity of a provided New Relic license key in a JavaScript application?

I have searched through the documentation but did not come across any API endpoint for this purpose.

UPDATE: Just to clarify, we do not have access to API keys that could be used to call an API endpoint and check the http status from the JSON response. We only have the license key itself available for performing this validity check.

Answer №1

Simply try accessing any of their endpoints with your API key. If the key is incorrect, you will receive an error message indicating so. This method essentially acts as a license key validation for all endpoints.

An example of the JSON response you may receive:

{"error":{"title":"No API key specified"}}

Answer №2

To ensure the validity of the license key, one could simply verify that it consists of a 40-character hexadecimal string. The Ruby agent adopts this method:

# A license key is an arbitrary 40 character string,
# usually looks something like a SHA1 hash
def validate_license_key_length
  key = Agent.config[:license_key]
  
  if key.length == 40
    true
  else
    ::NewRelic::Agent.logger.error("Invalid license key: #{key}")
    false
  end

agent.rb:443-454

Although the agent does not explicitly check for non-hex characters, one could employ a regex pattern like /^[0-9A-F]+$/ to perform such validation if deemed necessary.

In most cases of invalid keys, errors are likely due to incomplete pasting or accidental additional characters (typos). This approach should effectively handle such scenarios.
