Verify and retrieve information from the Dynamics CRM Web API with the help of Angular 2 (TypeScript)

How can one authenticate and query the Dynamics CRM Web API from a Single Page Application developed with Angular 2 (TypeScript)?

Initial research indicates that:

  • The Dynamics CRM (version 2016 or 365) instance needs to be registered as an application in Azure.
  • Users can authenticate with Azure-registered applications via Azure AD. Azure provides a client authentication library known as ADAL in JavaScript.

Past efforts involved cloning different Angular 2 repositories utilizing ADAL, like this repository, and modifying their configuration files to connect to my Azure application. However, these attempts consistently resulted in 401 (Unauthorized) cross-domain errors, which are explained in my separate inquiry.

Interestingly, using the same configuration (e.g. clientId) outlined in this JavaScript tutorial by Microsoft proved to be successful.

Answer №1

The problem with Access-Control-Allow-Origin is primarily related to the server-side, regardless of whether you're working with Angular 1 or Angular 2.

To determine if your domain is permitted to make requests, you can manually send an options request. For instance, you could test if the AJAX request from http://localhost:3000 is allowed by using the following request:

OPTIONS: https://example.crm.dynamics.com/api/data/v8.0/accounts
Authorization: Bearer {accessToken}
Origin: http://localhost:3000
Host: example.crm.dynamics.com
Access-Control-Request-Headers: authorization
Access-Control-Request-Method: GET

If the domain is permitted, the response will be similar to the one shown here (check Access-Control-Allow-Origin):

To resolve this issue, ensure that the server supports CORS. If not, consider creating a web API as a workaround proxy.

Answer №2

Fei Xue's code snippet shared on GitHub at this link has successfully authenticated with a Dynamics CRM application in Azure and accessed the Web API.

Past experiences with similar code samples have led to encountering 401 Unauthorized HTTP errors. The mystery of why this particular sample works while others fail remains unsolved for now.
