Each Application Programming Interface (API) connects differently. To begin with, check the current list of data source connectors to ensure that a connector does not already exist. You can see the list of available services on the Service Connectors page here for Klips or here for PowerMetrics.

If the API is not currently listed, you can then perform a web search for the API's REST connector to determine the authentication method. Best results are achieved by using the search terms service name API or service-name developers. Depending on the API, perform one of the following actions.

• For an API that uses basic authentication - username or password - use the web accessible connector. For more information see REST/URL Connector.
• For an API that uses an OAuth Token, contact support@klipfolio.com.
• For an API that uses an API key for authentication, add the API key to the end of the API connection URL. An API key is often used as a value in a query parameter or header. For more information on using the API key, refer to the API documentation.
• For an API that that requires a separate login URL/call and a data URL/call, use Two Step Authentication. For more information see Two-step authentication.
