Transaction ID in REST API

[Sagaya1]

Hi ,

I need to validate the duplicate request in my REST API call . For that I need to read and use the transaction ID which will be sent by the 3rd party user while he/she trigger the REST API. 

So could you help to read and access the transaction id ?

Regards,

Sagaya Rajan.

Have you tried adding a column for transaction id to the table that's being updated by the request and doing a query before insert/update to check for duplicate transaction id?

var reqheader = request.headers;
var transaction_id= reqheader.transaction_id;
