https://github.com/MicrosoftDocs/OData-docs/blob/main/Odata-docs/webapi/first-odata-api.md Hits: Postman Post some data to the web API app, using a tool such as HTTP REPL or [Postman] Triage note: This is just a reference link to Postman that can be deleted.

https://github.com/MicrosoftDocs/OData-docs/blob/main/Odata-docs/webapi/odata-expand.md Hits: Postman This tutorial uses Postman to test the web API. AND * Install Postman AND * Start Postman. Triage note: This looks like it might need cURL or some other option to test with. The instructions are not very specific for the actual testing but assumes Postman is used.

These two were from the Odata-docs repo that were not originally on our radar for repos to handle for this exercise.

If you decide to go with cURL, here are some examples topics we have that introduce and use cURL that might save some time: https://learn.microsoft.com/en-us/training/support/catalog-api-get-started-curl-vscode Test gRPC services with gRPCurl and gRPCui in ASP.NET Core | Microsoft Learn Get started with the Microsoft Learn Catalog API using curl and Visual Studio Code
