Call API Rest Camunda embedded

Camunda 7 Topics Discussion & Questions

Hi Camunda team,

I have a spring boot application with camunda embedded.

I would like to call these apis call within the microservice itself or call through Java.

1 - GET localhost:8081/rest/process-instance?businessKey={id}
2 - GET localhost:8081/rest/job?processInstanceId={id}
3 - PUT localhost:8081/rest/job/{id}/retries

Is it possible? call these apis with JavaDelegate or the microservice api itself?

It is indeed. If you’re running a JavaDelegate you’d have access to the engine’s JavaAPI so you can run any method that the REST API could enact.

Hi @Niall thank you for your reply, Can you tell me where I can find it in the documentation?

This is a good place to start:
https://docs.camunda.org/manual/7.16/user-guide/process-engine/process-engine-api/

Hello @Niall, thank you for your reply.

I tried to follow the documentation but when I try to retry an incident, it is creating a new one instead of retry the current incident.

My java code:

private void retryJob(String processInstanceId) {
        ManagementService managementService = processEngine.getManagementService();

        String jobId = managementService.createJobQuery().processInstanceId(processInstanceId)
                                        .list()
                                        .stream()
                                        .findFirst()
                                        .map(Job::getId)
                                        .orElse(null);

        managementService.setJobRetries(jobId, 1);
    }

    private String getProcessInstanceIdByBusinessId(String processDefinitionKey, String businessId) {
        RuntimeService runtimeService = processEngine.getRuntimeService();

        return runtimeService.createProcessInstanceQuery()
                             .processDefinitionKey(processDefinitionKey)
                             .list()
                             .stream()
                             .filter(processInstance -> processInstance.getBusinessKey().equalsIgnoreCase(businessId))
                             .findFirst()
                             .map(ProcessInstance::getProcessInstanceId)
                             .orElse(null);
    }
