Add a Clickatell gateway
After creating a Clickatell account on the Clickatell website you also have to create a new REST API integration and switch the integration on. You then get a REST API key that you use in the Clickatell gateway to access your Clickatell account.
If you use an older Communicator / Central Clickatell account you can still use that account with Diafaan SMS Server. The Communicator / Central API uses an (HTTP) API id, a username and a password to identify your account.
