A token and secret pair is a method to authenticate and enable access to secure data.
Token: The token is used in conjunction with the secret to authenticate the request.
Secret: The secret is the ‘password’ that is used to authenticate against the token. It is known as a token and secret pair because a token is associated with its secret (the pair).
Together they work to confirm the identity and authentication of a payment.
Each app has a Token and Secret Pair for Sandbox and Live.
