Hi @Himanshu_Pratap_Rana ,

We still feel that the input data is incomplete. We do not see the Json format or it’s Data. However, you have provided us with a Mail Body, where it is assumed we would have to replace the [Keywords] with the corresponding value in Json.

Do confirm on the other data and what is to be performed.
