Integrate Dynamics with External system using REST api

Hi,

Hope someone can help.

I have a task to create a bi-directional sync with an external application.

The external application supports REST api.

Below is what I am trying to achieve.

1. Create sync and fetch information into Dynamics using REST.

2. Whenever a new record gets created in the external application, it should also get created in Dynamics.

3. If any records gets updated/created in Dynamics, it should also get updated/created in the external application.(both system)

Your help and guidance would be great!
