Ajay You have to enable CORS (Cross origin Resource Sharing). This is because your web api is in another domain and your web client consuming web api is in other domain. For example if your API is hosted somewhere like www.Ajay.com and the client domain from where the API needs to be consumed is www.mukesh.com in that case web api needs to enable cors . To enable cors please refer https://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api Regards Mukesh Nayak
