Power Platform provides a variety of tools to extend the platform and user experience. If you need to work with the Dataverse, you can use the Dataverse Web API and Organization service.
Or develop your business logic by using the Dataverse plug-ins. You can use Data import, Synchronization, Virtual entities, Azure integration, and Webhooks for integration purposes.
Dataverse data integration can be defined as an inbound and outbound process. The inbound data integration brings data into the Dataverse database and the outbound - from the Dataverse.
There are two patterns to bring data in or out: pull and push. To trigger data out (push), the Dataverse uses the Event Framework that provides a capability to register the custom code to run on a specific event, like data update. You can use the Dataverse Plug-in tool to register the Plug- in or Webhooks to trigger the message to the third-party provider. In the case of an Automated flow, you can use the Common Data Service (current environment) trigger "When a row is added, modified or deleted." Reference:
