Hi @HemantAHK, could you double check that you’ve filled out the form we sent you after you finished the course? Check your messages in Udemy - you should find it there 
For anyone else who comes across this thread, if you’ve filled out the form to request a certificate from Rasa (the form we send you after you finish the course), you should be good to go! We process the certificates in batches, so it can take a few weeks for the certificate to reach you. If it’s been longer than 3 weeks, please send us a message through Udemy and we’ll look into it for you!
