Posted on by Community Member

Hi, I am a newbie to Dynamics CRM online using trial version. how can i access crm data with rest api from some rest client like

url: https://myurl/api/data/v8.2 ? I am not using Active Directory. Currently i am sending GET request with username and password in header, but response is HTTP Error 401 - Unauthorized: Access is denied.

I am pretty sure about some oauth token api, but how can i get token through rest api to consume it in getting rest of data.

Your earliest response will be highly appreciated.

Thanks

Hi,

The tenant id for your Office 365 tenant is displayed as part of the URL:

manage.windowsazure.com/tenantname

See: https://support.office.com/en-us/article/Find-your-Office-365-tenant-ID-6891b561-a52d-4ade-9f39-b492285e2c9b?ui=en-US&amp
