Camunda 404 Rest API Error

I have created my own Camunda Spring boot application and trying to use the Rest API for the same. getting 404 error.

Do I need to deploy engine-rest along with my application to access Rest API?
example I tried below
http://localhost:8080/process-definition/key/taskform/start

Please suggest me at the earliest?

If you’ve added the the REST API you should be able to test it via
localhost:8080/rest/engine

I get sample app from git, not started using http://start.camunda.com

I created new app using http://start.camunda.com and then accessed the following URL : localhost:8080/rest/engine so below is the output.
[{“name”:“default”}]

when I am trying with this
http://localhost:8080/process-definition/key/Pierian-Camunda-process/start, so getting 404 error? please suggest

This means the REST API is working correctly.

The rest call is incorrect - you’re forgetting to add the rest endpoint:

http://localhost:8080/rest/process-definition/key/Pierian-Camunda-process/start,

@Niall. I have downloaded the package from start.camunda.com
i have selected the options REST API and WebApps under camunda modules.
However when i access the http://localhost:8080/rest/engine , i am getting No message content error. Please assist.

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

No message available

@Bharath_Kumar1 try with engine-rest

How are you accessing this api? Postman or browser or restclient?
