This API reference is useful if you are trying to hit workflows from:
  1. An external Domo Instance
  2. An environment from outside of Domo
  3. A script running in Domo’s Jupyter Workspaces
If you are looking to hit a workflow from a Domo App, see the App Framework API Reference for Workflows and the guide on how to hit a workflow from a Domo App. If you are unfamiliar with how to authenticate against Product APIs, please see this overview page. For more background on Workflows, check out the Knowledge Base for an overview.

​
Start a Workflow

Starts a Workflow and returns details about the Workflow Instance. Method: POST
Endpoint: https://{instance}.domo.com/api/workflow/v1/instances/message Request Body
Property NameTypeRequiredDescription
messageNameStringRequiredMessage passed to start the Workflow Instance, usually "Start {workflow_name}
versionStringRequiredThe version identifier e.g. 0.0.1
modelIdStringRequiredThe id of the Workflow
dataObjectRequiredThe start parameters required to kick off the Workflow.

​
Input Parameters

For the data object containing the start parameters required to run the workflow, be careful to structure this object so it is consistent with the input types that you’ve already defined in your workflow. The valid input type options are:
  • boolean
  • date
  • dateTime
  • decimal
  • duration
  • number
  • object
  • person
  • dataset
  • group
  • text
  • time
You may pass in lists containing the above types and may also nest additional information in object type inputs.
A simple example of a workflow that takes two numerical inputs, might look like the following: 
{ "parameter1": 13, "parameter2": 7 }
Example 
{
  "method": "POST",
  "url": "https://{instance}.domo.com/api/workflow/v1/instances/message",
  "headers": {
    "X-DOMO-Developer-Token": "",
    "Content-Type": "application/json"
  },
  "body": {
    "messageName": "Start {{workflow_name}}",
    "version": "{{workflow_version}}",
    "modelId": "{{workflow_id}}",
    "data": {}
  }
}
HTTP Response Returns the information about the instance of the Workflow that was just started. The status property can take the values null, IN_PROGRESS, CANCELED, or COMPLETED. A status of null might be valid. It just means the workflow hasn’t reported back as started yet.
