1. API Testing:

After you create an app and enable API products for it, you can connect the app to those API products in the mock environment.

1. Click API Catalog on the menu bar.
2. Choose the API product.
3. Go to Reference Documentation and click Authorize to connect it.
4. In the Authorization popup, enter the Client ID for your app. Client ID is available on the apps page in your My Apps list (see the App registration section above), and the API Key value is the equivalent to your Client ID. Once authorization is complete, you can submit requests to the endpoints.
    

2. Specifics around datatypes

1. Date:

   1. If we add date filter format as dd-mm-yyyy, it is not filtering. so our list contacts filter as we added validation it is showing error message.  Currently filter with date accepts all other date formats such as: yyyy-mm-dd, mm/dd/yyyy, mm/yyyy, yyyy/mm, jan2023, 2023jan, dec12, 12/dec, 12-dec
