ISSUE:

WHEN I POSTING THROUGH THE POST MAN BY GIVING CORRECT TOKEN , API KEY & THE FILES PARAMETERS TO BE EMBEDDED, I AM GETTING MESSAGE "202-ACCEPTED" BUT THE PROCESS IS NOT COMPLETED. IT IS SAYING "The reqeust has been accepted for processing , but the processing has not been completed.The request might or might not be evnetually acted upon, as it might be disallowed when processing actually takes place".

Please kindly provide the solution.
