Sync API

The Sync API allows you to make synchronous, blocking calls to the Mambu Process Orchestrator (MPO) by issuing calls to a sync server instead of the standard MPO base URL.

Requests to the standard MPO base URL return confirmation that the call was received, but the call is non-blocking for your application code. The process or state diagram output is returned later as an additional response, or you must make another call to check its status.

When using the Sync API, the output is returned synchronously, and your request will be blocked waiting for the outputs.

Use the API Call node to invoke a sync API request.

How it works

Every MPO instance has a corresponding sync server with the following base URL:

https://TENANT_NAME-syncapi.mpo.mambu.com/

To make synchronous calls to MPO, you must issue calls to the sync server base URL. You may also issue synchronous calls to your MPO sandbox using the following base URL:

https://TENANT_NAME-syncapi.sandbox.mpo.mambu.com/

Synchronous requests use the sync server as an intermediary to make the request for you. Your request will be blocked until the process or state diagram output is returned or the request times out.

Configuring a sync API request in the UI

To configure a synchronous request, you need to:

• Add the API Call node after the step from which you need an output.
• Provide the {{__callback_url}}.
• Specify the parameters which are to be sent to the task.

Generating a sync API request

Once the process or state diagram is set up to receive a sync API request, send a request to the sync Server to invoke a task. This synchronous request must include a signed hash to ensure that requests are coming from a known sender.

For more information on how to create a signature, see API Basics.

Request body

The request body must include either the process ID or an alias of the task you want to invoke and any parameters you want to pass into the task. You may provide an optional timeout for the request, in seconds. If you do not specify a timeout, the default value of 60 seconds will be used.

Example using the process ID

{
     "timeout": 30,
     "ops": [{
          "conv_id": 33220,
          "company_id": "i123456789",
          "type": "create",
          "obj": "task",
          "data": {
               "param": 1
          }
     }]
}

Example using an alias

{
     "timeout": 30,
     "ops": [{
          "obj_alias": "an-alias",
          "company_id": "i123456789",
          "type": "create",
          "obj": "task",
          "project_id": 27443,
          "stage_id": 33164,
          "data": {
               "param": 1
          }
     }]
}

Responses

{
    "ops": [
        {
            "proc": "ok",
            "data": {
                "info": {
                    "param_1": "value_1",
                    "param_2": "value_2",
                    "param_3": "value_3"
                }
            }
        }
    ],
    "request_proc": "ok"
}
