Customizing for Your Environment

Section titled “Customizing for Your Environment”

To deploy Plxtra effectively, you will need to integrate it with your business systems such as:

  • CRM
  • Identity and access management
  • Monitoring tools

Plxtra does not include these business systems such as they are difficult to standardise and are very dependent on organisations’ other infrastructure. They vary considerably from organisation to organisation. Instead, Plxtra provides APIs which enable Plxtra to be tightly integrated into an organisation’s business systems.

In addition, you may also need to develop or configure:

  • Exchange connectivity
  • Custom extensions
  • Specialized data feeds

APIs are provided for these integrations and customisations.
