@shama Please do not create 2nd accounts and use it to post the same issue on multiple topics… I have removed all of them and the unnecessary 2nd account.

As for your new issue, I moved tit into a new topic.

First you have not formatted your code as required… Please repost your code properly.

Secondly, if you would search and read other API related topics and look at the examples on the API document page you might see that you are using quotes around your values that are not needed.
