Overview of D365 Rest APIs

The Dynamics 365 REST APIs are a collection of APIs that allow you to access data and functionality in Dynamics 365 Customer Engagement (CE) and Dynamics 365 Finance and Operations (F&O). These APIs are designed to be easy to use and to provide a consistent interface for interacting with Dynamics 365.


The REST APIs use the OData (Open Data Protocol) standard, which is a protocol for querying and updating data over the web. OData is based on the AtomPub and JSON standards, which make it easy to consume the APIs using a wide range of platforms and programming languages.


To use the Dynamics 365 REST APIs, you will need to authenticate your requests using Azure AD authentication. You can use either a client secret or a client certificate for authentication, depending on your needs.


Once you have authenticated your requests, you can use the REST APIs to perform a wide range of operations, including:

  • Reading and writing data from Dynamics 365

  • Executing custom functions and actions

  • Working with metadata to create, update, and delete entities and fields

  • Querying data using OData query parameters

You can find more detailed documentation and examples for the Dynamics 365 REST APIs at the following links:
