An n8n workflow with a form for an event’s details and a picture prompt. OpenAI draws the art, Bannerbear lays it on a template with the text, and Discord gets the banner. Event banners made with AI art and a Bannerbear template is an n8n workflow in the Marketing \& SEO category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page or copy its JSON, then import it into an n8n canvas. Nothing runs until you activate it in n8n. ## About ### What it is This n8n workflow makes an event banner from a short form. You enter a template, the event’s title, place and date, and a prompt for the picture. OpenAI draws the picture, and Cloudinary hosts it. Bannerbear places it and the text on a template, and the finished banner is posted to a Discord channel. Seven nodes run it, beside eight sticky notes. ### Who it suits Community and event teams who announce events often and want a banner on brand each time. Skip it if you have no Bannerbear template, since the layout comes from there. Who uses it, and how | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Community | Community managers | Announce meetups | A manager enters a date and a venue and posts a banner to the server. | | Events | Event organizers | Make a banner for each talk | An organizer makes one banner for each speaker from the same template. | | Education | Course teams | Announce workshops | A course lead posts a workshop banner with art that fits the topic. | | Marketing | Small agencies | Draft social banners fast | A designer gets a first banner to refine in minutes. | You need some n8n and four accounts: import a file, add three credentials, and paste a handful of ids and names. ### Where to use it Any n8n that can reach OpenAI, Cloudinary, Bannerbear and Discord will run it. The form runs inside n8n, so your team opens its address. - n8n Cloud: import the file there and share the form address - Your own n8n server: the same file and steps - Bannerbear: the template that sets the layout - Discord: the channel that gets the banner ### How to set it up Download saves a zip with `workflow.json` and Mindket’s setup notes in your downloads folder. Setup takes three credentials, an unsigned Cloudinary preset, a Bannerbear template and a Discord channel. What you need first | Need | Detail | | --- | --- | | n8n | On n8n Cloud or on a server of your own | | OpenAI | An API key | | Cloudinary | An account and an unsigned upload preset | | Bannerbear | A template with four layers, and a project key for its version 2 API | | Discord | A bot on your server that may post in the channel | 1. In n8n, create a workflow, open its menu, choose Import from File and pick `workflow.json`. 2. Add an OpenAI credential and select it in `Generate AI Banner Image`. 3. In `Upload to Cloudinary`, replace `` and ``. 4. In `Set Parameters`, replace `` and ``. 5. Add a Bannerbear credential and select it in `Send to Bannerbear Template`. 6. Add a Discord bot credential and select it in `Discord`. Replace `` and ``. 7. Open the form’s test address, fill it in and submit. ### How to use it Open the form, fill it in and submit. The banner appears in the Discord channel a short while later. Make the first one with a plain prompt. What to change for a different result | To change | Where | | --- | --- | | The layout | The Bannerbear template and the layer names in \`Send to Bannerbear Template\` | | The picture | The prompt on the form, and the size and quality in \`Generate AI Banner Image\` | | The message | The text in \`Discord\` | | Where it goes | Swap \`Discord\` for another network’s node | ### Example A community manager picks the first template and enters a meetup’s title, a city and a date. The prompt asks for a night skyline in blue. OpenAI draws the skyline, and Cloudinary hosts it. Bannerbear places it behind the title, the city and the date, and Discord shows the banner under a line that announces the event. ### For newcomers and experts **If you are new.** n8n draws a workflow as boxes joined by lines, and each box, a node, does one job. Here one box takes the form, one draws, one stores the picture, one builds the banner and one posts it. Try it once with a short title. **For experts.** The OpenAI node returns the picture as a binary field, and an HTTP Request sends it to Cloudinary as multipart form data. The Bannerbear node waits for the image, and a second HTTP Request downloads it for Discord. Where to look closer | Node | What it does | What to know | | --- | --- | --- | | \`Generate AI Banner Image\` | Draws the picture | Version 2.3 of the node, with \`gpt-image-2.6-flare\` | | \`Upload to Cloudinary\` | Stores the picture and returns its address | Authentication is none, because an unsigned preset needs no key | | \`Send to Bannerbear Template\` | Fills four layers and waits for the image | It polls every two seconds, up to ten tries | | \`Download Banner\` | Fetches the finished image | It reads \`image\_url\_jpg\`, else \`image\_url\` | ### Good to know An unsigned preset’s name can be found in a web page’s code, so allow only the formats you need and turn on `disallow_public_id` in Cloudinary. - The repair: the picture step drew with DALL·E 3, which OpenAI’s deprecations page, read on 12 November 2026, lists as removed on 12 May 2026. This copy names \`gpt-image-2.6-flare\`, and the node still returns binary \`data\` - Bannerbear: n8n’s node calls the version 2 API, and Bannerbear’s docs say version 5 keys do not work there. A banner that takes over about twenty seconds ends the run with an error - Placeholders: the template ids, the Cloudinary cloud name and preset, and the Discord ids are yours to fill in - Layers: your template needs the layers \`placeholder\_image\`, \`placeholder\_text\`, \`placeholder\_location\` and \`placeholder\_date\`, or change the names in the node - Not run: this copy was not run against OpenAI, Cloudinary, Bannerbear or Discord - Your data: the prompt goes to OpenAI, the picture to Cloudinary and Bannerbear, and the banner to Discord - Credentials: the JSON holds none ## README ```markdown # Event banners made with AI art and a Bannerbear template An n8n workflow with a form for an event's title, place, date and a prompt for its picture. OpenAI draws the picture, Cloudinary hosts it, and Bannerbear places it and the event text on a template. The finished banner is posted to a Discord channel. ## What is inside - `workflow.json`: the workflow as n8n exports it, fifteen nodes: seven that do the work and eight sticky notes. It holds no credential. - `README.md`: these notes. ## What we changed from the original copy - The credential links are gone. Select your own for OpenAI, Bannerbear and Discord. The Cloudinary step needs none. - The picture step was the OpenAI node at version 1.3, which draws with DALL·E 3 unless told otherwise, and the file names no other model. OpenAI's deprecations page, read on 12 November 2026, lists DALL·E 3 as removed on 12 May 2026. The node is now version 2.3 and names `gpt-image-2.6-flare`. The deprecations page lists `gpt-image-1` for shutdown on 23 October 2026 and `gpt-image-2` on 10 February 2027, and names the 2.5 and 2.6 `sunburst` and `flare` models as replacements. - The options are `1024x1024` and quality `medium`. The old quality, `standard`, is a DALL·E 3 value. The node still returns the picture as the binary field `data`, which the Cloudinary step reads. - The Cloudinary address holds your cloud name as ``, and the upload preset is ``. The step linked a Query Auth credential. Cloudinary's documentation says an unsigned upload needs only `file` and `upload_preset`, with no signature or `api_key`, so the node's authentication is set to none. The preset must be unsigned. - The form offered two Bannerbear templates by the author's own names, each tied to the author's template id. The choices are `Template one` and `Template two`, tied to `` and ``. - `Download Banner` read `image_url_jpg`. Bannerbear's version 2 reference lists `image_url` only, so the node reads `image_url_jpg` when it exists and `image_url` otherwise. - The Discord server and channel are `` and ``. The file option names the field `data` outright. - The form's address was a random identifier. It is `event-banner` now, and the form is titled `Event banner maker`. - The notes are rewritten. One showed a picture on the author's own Cloudinary account, and it is removed. Another said the banner goes to X, but the workflow posts to Discord, and the notes now say Discord. - Nothing else. ## Before you start - An n8n instance, on n8n Cloud or your own server. - An OpenAI API key. - A Cloudinary account with an unsigned upload preset. - A Bannerbear account, a template whose layers are named `placeholder_image`, `placeholder_text`, `placeholder_location` and `placeholder_date`, and a project API key for Bannerbear's version 2 API. Its documentation says a version 5 key does not work with version 2 endpoints. - A Discord bot that is on your server and may post in the channel. ## Set it up 1. In n8n, create a workflow, open its menu and choose Import from File. Pick `workflow.json`. 2. Add an OpenAI credential and select it in `Generate AI Banner Image`. 3. In `Upload to Cloudinary`, replace `` in the address and `` in the query. 4. In `Set Parameters`, replace the two template ids. Rename the two choices in the form if you like, and keep the two sets of names the same. 5. Add a Bannerbear credential and select it in `Send to Bannerbear Template`. If your layers have other names, change them in its modifications. 6. Add a Discord bot credential and select it in `Discord`. Replace `` and ``. 7. Open the form's test address, fill it in and submit. ## How a run goes 1. `n8n Form Trigger` shows a form with a template choice and the title, place, date and image prompt. 2. `Set Parameters` turns the template choice into a template id and copies the other fields. 3. `Generate AI Banner Image` draws the picture from the prompt. 4. `Upload to Cloudinary` posts the file with the upload preset. The answer holds `secure_url`. 5. `Send to Bannerbear Template` fills four layers: the picture, taken from `secure_url` with `f_auto,q_auto` added, then the title, the place and the date. It waits for the image, trying up to ten times. 6. `Download Banner` fetches the finished banner. 7. `Discord` posts the message `New Event Alert!` with the title, place and date, and attaches the banner. ## Change the look - The layout: the Bannerbear template, and the layer names in `Send to Bannerbear Template`. - The picture: the prompt on the form, and the size and quality in `Generate AI Banner Image`. - The message: the text in `Discord`. - Where it goes: swap `Discord` for another social network's node. - The file host: replace `Upload to Cloudinary` with another host that gives back a web address. ## Good to know - n8n's Bannerbear node calls the version 2 API and polls every two seconds, up to the number of tries you set, which is ten. A banner that takes longer ends the run with an error. - An unsigned preset's name can be found in a web page's code. Cloudinary's documentation advises allowing only the formats you need with `allowed_formats` and turning on `disallow_public_id`. - Each run costs one OpenAI image, one Cloudinary upload and one Bannerbear image. - This copy was not run against OpenAI, Cloudinary, Bannerbear or Discord. - The prompt goes to OpenAI, the picture to Cloudinary and Bannerbear, and the banner to Discord. - The JSON holds no credential. ``` ## What is in it 3 files, 19 KB, downloaded as a zip. ```text NOTICE.md 643 B README.md 6 KB workflow.json 13 KB ``` ## Workflow check Checked by Mindket on 13 Nov 2026.
