How to pass processDefinitionKey in REST URL

[vrdhn]

I want to start a process and I know this is how I start using REST service:
http://localhost:8989/activiti-rest/service/runtime/process-instances
Method: POST
{"processDefinitionKey":"PurchaseRequestProcess",
"variables":[
  {"name":"formId","value":"1"},
  {"name":"requesterId","value":"kermit"}
]}
Unfortunately, I develop my application using Oracle Apex. So by default, it only provides the developer to fill variable and there is no place to pass processDefinitionKey data.
Is there anyway to pass the value of processDefinitionKey in the URL itself?
Please I am so confuse and I really need help in this. Thank you.

From this URL I can get the key.
http://localhost:8989/activiti-rest/service/repository/process-definitions/Process:1:43
How do I pass the key into another URL?
Like this? http://localhost:8989/activiti-rest/service/runtime/process-instances/processDefinitionKey?Process

No, that's not possible.
Not sure if I'm following … this is a very typical approach for doing an HTTP POST (the params are in the body)

[vrdhn]

If that's not possible, then is there any way to replace the value of formId and requesterId?
I want the value of formId and requesterId are flexible..

um … yes. It's in the body of the json you have, it's whatever you want.
Don't think we're on the same page here …
