Interact with Midjourney using Discord API • Part I
useapi.net
Posted on September 14, 2023
This practical guide shows you how to create basic automation using Midjourney /imagine command as an example.
For this exercise, you’ll need Discord account with active Midjourney subscription, $10 Basic Plan will do just fine.
Follow these simple steps to obtain:
Discord server id number, referenced in this article as
server_idDiscord channel id number, referenced in this article as
channel_idDiscord token, referenced in this article as
discord_token
We will be using listed below Discord API public endpoints:
Application Commands to get Midjourney imagine command details and post imagine interaction to desired Discord channel
Get Channel Messages to retrieve imagine interaction(s) results (messages) from Discord channel
Please feel free to use public Postman collection referencing Discord API mentioned in this article. Make sure to place your values into collection variables and save them before executing GET and POST collection calls:
Discord API authorization
All Discord API calls mentioned here require HTTP Authorization header with discord_token, example:
Authorization: discord_token
Retrieve imagine Discord interaction details
Execute application-commands GET request https://discord.com/api/v10/channels/channel_id/application-commands/search?type=1&include_applications=true&query=imagine
Response body:

We will need application_commands[0] object which has imagine command details, let’s extract it for future references:

Fields
application_idandapplication_commandshould be set to values extracted in step above.Place your Midjourney prompt into
data.options[0].valuefield.session_idcan be just any random integer number, if you using linked above Postman collection this value will be autogenerated by Postman.
HTTP Response Status should be 204 No Content, any other response status indicate problem with your payload.
Finally retrieve imagine command results

The Discord endpoint for messages returns the top 50 messages from channel_id, with the most recent returned first. Depending on Midjourney settings and servers load, it can take anywhere from approximately 20 seconds (fast mode) to 10 minutes (relax mode) to generate an image.
You can execute the above call in the loop with 10…20 secs delay between calls until components array is not empty. Then extract the generated image from attachments[0].url field.
In our next article, we will cover ways to detect Midjourney prompt moderation, the execution of Midjourney upscale or create variations and enhance or modify button commands.
