How do I find the Tenant ID of my SharePoint Online Account using SPFX

Question

I want to get Tenant Id of my SharePoint online site using SPFX.

Is there any way to get it?

Answer 1

SO, Finally i got the solution for that. For that you have to call API and i.e. https://your_site.sharepoint.com/_vti_bin/client.svc.

I am providing the function to get TenantID.

static getTenant() {

const request = new Request('https://{your_site}.sharepoint.com/_vti_bin/client.svc', {
  method: 'GET',
  headers: new Headers({
    'Authorization': 'bearer'
  })
});
return fetch(request).then(response => {
  var data = response.headers.get('WWW-Authenticate').split(',');
  return data;
  }).catch(error => {
  return error;
});
}

You will get the Bearer realm component and that's your tenant ID.

or you can get it by other way.

Follow the article to get TenantID i.e

SPFx components contain the current tenant id information in the context object as well:

this.context.pageContext.aadInfo.tenantId._guid
