A method for managing application configurations and associated credentials of a unified collaboration application, the method comprising: receiving, by an application integration management platform of a centralized computing device, an indication from an end-user computing device that an integration of a cloud application is to be installed and linked to a unified collaboration application, the cloud application running on a cloud application provider computing device connected to the centralized computing device over a network, and the centralized computing device including a credential management platform configured to provide a central location for a user to create and manage credentials for integrations of a unified collaboration application; installing, by the application integration management platform, the integration, wherein installing the integration includes generating a unique identifier of the integration and saving an application record that includes the unique identifier of the integration to an available applications database of the application integration management platform, wherein the available applications database is usable by a cloud application marketplace to identify available applications; receiving, by the application integration management platform, configuration input for the integration from the end-user computing device; storing, by the application integration management platform, the configuration input in an input application configuration database of the application integration management platform; receiving, by the application integration management platform, an enablement message from the end-user computing device indicating the integration is to be enabled; and transmitting, by the application integration management platform, an enablement notification to an application provider of the cloud application, wherein the enablement notification is usable to identify the integration. receiving, by an application integration management platform of a centralized computing device, an indication from an end-user computing device that an integration of a cloud application is to be installed and linked to a unified collaboration application, the cloud application running on a cloud application provider computing device connected to the centralized computing device over a network, and the centralized computing device including a credential management platform configured to provide a central location for a user to create and manage credentials for integrations of a unified collaboration application; installing, by the application integration management platform, the integration, wherein installing the integration includes generating a unique identifier of the integration and saving an application record that includes the unique identifier of the integration to an available applications database of the application integration management platform, wherein the available applications database is usable by a cloud application marketplace to identify available applications; receiving, by the application integration management platform, configuration input for the integration from the end-user computing device; storing, by the application integration management platform, the configuration input in an input application configuration database of the application integration management platform; receiving, by the application integration management platform, an enablement message from the end-user computing device indicating the integration is to be enabled; and transmitting, by the application integration management platform, an enablement notification to an application provider of the cloud application, wherein the enablement notification is usable to identify the integration.
