# Credential API Group

This section covers the methods involved in implementing a Docusign Credential API. The Docusign Credential API can be used to authenticate with an email and password to acquire your API credentials. The credentials can then be used to access the Docusign Connect API methods described earlier. If you have an integration key from Docusign, you can place it in front of the email argument bracketed, “\[“ and “]”.

The Docusign Credential API exposes the following methods:

* [Login](Login) – Allows you to authenticate with an email and password to retrieve your API credentials required to access the Docusign Connect API.
* [Ping](Ping) – Allows you to validate that the Credential API is alive.
* [GetAuthenticationToken](GetAuthenticationToken) –This can be used to get a one-time-use URL with an authentication token to launch the Docusign member system.
* [RequestSenderToken](RequestSenderToken) – This is used to get a one-time-use login token that allows the user to be placed into the Docusign sending wizard.
