The Currencycloud API authentication and authorization endpoint. Submit a login ID and API key for a Currencycloud account. On successful login, a temporary authentication token is returned. An authentication token is required to make requests to all other endpoints in the Currencycloud API. Tokens expire after 30 minutes of inactivity. Token requests are limited to 10 calls per minute. For security, Currencycloud accounts are disabled when four unsuccessful login attempts are made within a short period. Account holders must [contact support](https://developer.currencycloud.com/support) to reactivate their account.
