## Overall flow
This diagram demonstrates how the different areas of our API are linked together. For more information about each element in this diagram, check out our [Definitions](https://docs.casava.co/definitions) page.
## Policy Change Management
An insurance policy can generally transition through the states shown in the diagram.
For example, a typical flow could see a policy go from:
Quoted -> Issued -> Expired or Cancelled.
Check out the [Get Policy Application Details page](https://docs.casava.co/reference/api-reference/policy/get-policy-application-details) in the API reference guide for how to get insurance policy status.
The full list of statuses are as follows:
1. Quoted
2. Applied
3. Accepted
4. Invalidated
5. Issued
6. Expired
7. Renewed
8. Canceled
9. Paused
