Task Object

Each Midjourney request submission returns a task object. The task object contains the following fields:

Field	Type	Description
`id`	string	Unique task identifier
`action`	string	Task type: `IMAGINE`, `UPSCALE`, `VARIATION`, `BLEND`, `DESCRIBE`, etc.
`status`	string	Task status
`prompt`	string	Submitted prompt
`promptEn`	string	Translated English prompt
`description`	string	Task description
`submitTime`	number	Submission time (millisecond timestamp)
`startTime`	number	Processing start time
`finishTime`	number	Completion time
`progress`	string	Progress percentage, e.g. `"100%"`
`imageUrl`	string	Generated image URL
`failReason`	string	Failure reason (only present on failure)
`properties`	object	Additional properties
`buttons`	array	List of available action buttons

Task Status

Status	Description
`NOT_START`	Task submitted, waiting to be processed
`SUBMITTED`	Task submitted to Midjourney
`IN_PROGRESS`	Task is being processed
`SUCCESS`	Task completed
`FAILURE`	Task failed

Action Buttons

After a task completes, the buttons field contains available follow-up actions:

{
  "buttons": [
    {"customId": "MJ::JOB::upsample::1::hash", "emoji": "U1", "label": "U1", "style": 2},
    {"customId": "MJ::JOB::upsample::2::hash", "emoji": "U2", "label": "U2", "style": 2},
    {"customId": "MJ::JOB::upsample::3::hash", "emoji": "U3", "label": "U3", "style": 2},
    {"customId": "MJ::JOB::upsample::4::hash", "emoji": "U4", "label": "U4", "style": 2},
    {"customId": "MJ::JOB::variation::1::hash", "emoji": "V1", "label": "V1", "style": 2},
    {"customId": "MJ::JOB::variation::2::hash", "emoji": "V2", "label": "V2", "style": 2},
    {"customId": "MJ::JOB::variation::3::hash", "emoji": "V3", "label": "V3", "style": 2},
    {"customId": "MJ::JOB::variation::4::hash", "emoji": "V4", "label": "V4", "style": 2}
  ]
}

Use the customId to call the Action endpoint to perform the corresponding operation (upscale, variation, etc.).

API Endpoints Overview

Method	Endpoint	Description
POST	`/mj/submit/imagine`	Submit an Imagine task
POST	`/mj/submit/action`	Execute an action (upscale, variation, etc.)
POST	`/mj/submit/blend`	Blend images
POST	`/mj/submit/describe`	Describe an image
POST	`/mj/submit/modal`	Submit modal confirmation
POST	`/mj/submit/shorten`	Shorten a prompt
GET	`/mj/task/{id}/fetch`	Query a single task
POST	`/mj/task/list-by-condition`	Batch query tasks
GET	`/mj/task/{id}/image-seed`	Get image seed

Midjourney tasks are processed asynchronously. After submission, you need to poll the task status. It is recommended to query every 3-5 seconds until the status becomes SUCCESS or FAILURE.
