Important
We will be officially sunsetting v1. Starting from March 1, 2024 all calls will be routed to v2 endpoints. Although this change will be transparent to our customers we strongly advise you to update your code to use the v2 endpoints as they provide many more options.

Use this endpoint to submit the Midjourney /blend command to your Discord Midjourney channel. Results obtained as a callback via optional parameter replyUrl or by querying jobs/?jobid=jobid endpoint.

Your current Midjourney Settings and Presets will be used, log in to your Discord Midjourney account to adjust them to your liking.

It is important not to use the Midjourney account setup for API access for any purposes other than its intended use, such as executing /imagine or any other Midjourney commands manually or in conjunction with any other automation tools. The useapi.net API internally tracks the usage of the Midjourney account, including the number of currently active executions. Using it for other activities may cause API to function incorrectly.

  • blendUrls is required, must contain at least 2 valid URL image links.
    Up to 5 URL image links supported.

  • discord, server, channel are required, see Setup Midjourney for details.

  • maxJobs is optional, if not provided defaulted to 3.
    This value should be the same or less than your Midjourney subscription plan Maximum Concurrent Jobs. Currently, it should be 3 or less for Basic and Standard plans and 12 or less for Pro and Mega plans.
    Important Specifying a higher number than supported by your Midjourney subscription will prevent API from functioning properly.

    We recommend using sites like webhook.site to test callback URL functionality.

    One of URLs did not pass the Midjourney content moderation policy.
    If you wish to appeal login to Discord, navigate to the configured API server and channel, locate the moderation message, and proceed with the appeal process. Do not mention the fact that you’re using API for Midjourney request generation as it is prohibited by Midjourney policy and may result in a permanent ban of your Midjourney Discord account.
