# Making requests
The Open Data Protocol (OData) is a data access protocol built on core protocols like HTTP and commonly accepted methodologies like REST for the web. There are various kinds of libraries and tools can be used to consume OData services.
These examples are from https://www.odata.org/getting-started/basic-tutorial/ (opens new window), updated as Lodata examples.
The examples in this documentation are an introduction to OData requests and do not cover all the available functionality. See the OData protocol documentation for more extensive documentation and examples.
