Calling Camunda process using PostMan REST API

 Best of camunda is we can perform operatio using REST API call. i.e. let say you have one bpnm file and uploaded on Camunda server and you want to access the process then you can do using REST api call.

our url will be

http://localhost:8080/engine-rest/process-definition/siddhu_process_1:1:bc2e074e-e35d-11ed-8f2e-7e7a91225434/start

{
“variables”: {
