Question

Trying to call graph calendar API using ClientSecret flow from java code but I am getting url not found error from code.

Below is the code being used - the same ClientSecret flow works for getting the AD details of user.

public class ClientSecretFlow {

private final static List<String> SCOPES = Arrays.asList("https://graph.microsoft.com/.default");

public static void main(String[] args) throws Exception {

    final ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
            .clientId("81df77....").clientSecret("BHf7Q.....")
            .tenantId("c4714741....").build();

    final TokenCredentialAuthProvider tokenCredentialAuthProvider = new TokenCredentialAuthProvider(SCOPES,
            clientSecretCredential);


    final OkHttpClient httpClient = HttpClients.createDefault(tokenCredentialAuthProvider);


    String json = "{\"subject\": \"Event testing\",\"start\": {\"dateTime\": \"2021-12-15T08:34:45.317Z\",\"timeZone\": \"UTC\"},\"end\": { \"dateTime\": \"2021-12-20T08:34:45.317Z\", \"timeZone\": \"UTC\"}}";

    RequestBody formBody = RequestBody.create(MediaType.parse("application/json"), json);


    Request calendarrequest = new Request.Builder()
            .url("https://graph.microsoft.com/v1.0/users/{userid}/calendar/events").post(formBody)
            .build();

    try {
        Response response = httpClient.newCall(calendarrequest).execute();

        System.out.println(response);

        // Do something with the response.
    } catch (IOException e) {
        e.printStackTrace();
    }
    // sending outlook mails for calendar invite

}

}

Hi @Ravindran, Rohit

This error is usually because your user does not have an MS 365 license, make sure your user has been granted an MS 365 license before calling the /calendar/events endpoint.
