Web API Query Data Sample (Client-side JavaScript)
Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
This sample demonstrates how to perform basic query requests using the Dynamics 365 Web API using client-side JavaScript
Note
This sample implements the operations detailed in the Web API Query Data Sample and uses the common client-side JavaScript constructs described in Web API Samples (Client-side JavaScript)
In this topic
Prerequisites
Run this sample
Code sample
Prerequisites
To run this sample, the following is required:
Access to Dynamics 365 online or on-premises version 8.0 or higher.
A user account with privileges to import solutions and perform CRUD operations, typically a system administrator or system customizer security role.
Run this sample
To run this sample, go to Microsoft CRM Web API Query Data Sample (Client-side JavaScript) and download the sample archive file: Microsoft CRM Web API Query Data Sample (Client-side JavaScript).zip. Extract the contents of the sample archieve and locate the WebAPIQueryData_1_0_0_0_managed.zip managed solution file. Import the managed solution into your Dynamics 365 organization and run the sample. For instructions on how to import the sample solution, see Web API Samples (Client-side JavaScript).
Code sample
This sample includes two web resources:
WebAPIQuery.html
WebAPIQuery.js
WebAPIQuery.html
The WebAPIQuery.html web resource provides the context in which the JavaScript code will run.
