This n8n workflow shows an easy way to automate the creation of social media assets using AI and a service like BannerBear. Designed for the busy marketer, leveraging AI image generation capabilities can help cut down production times and allow reinvesting into higher quality content. How it works This workflow generates social media banners for online events. Using a form trigger, a user can define the banner text and suggest an image to be generated. This request is passed to OpenAI's Dalle-3 image generation service to produce a relevant graphic for the event banner. This generated image is uploaded and sent to BannerBear where a template will use it and the rest of the form data to produce the banner. BannerBear returns the final banner which can now be used in an assortment of posts and publications. Requirements A BannerBear.com account and template is required An OpenAI account to use the Dalle-3 service. Customising the workflow We've only shown a small section of what BannerBear has to offer. With experimentation and other asset generating services such as AI audio and video, you should be able to generate more than just static banners!

Quick overview This workflow runs on a Mon/Wed/Fri schedule to generate an Instagram carousel or TikTok slideshow using OpenAI (GPT-4o-mini and gpt-image-1), sends the slides to Telegram for approval, and only then uploads the images and schedules the post via PostFast. How it works Runs every Monday, Wednesday, and Friday at 8am and loads your brand, topics, slide count, platform filter, and Telegram chat ID. Retrieves your connected social accounts from PostFast and keeps only accounts that are connected and match the selected platforms. Uses OpenAI (gpt-4o-mini) to write a carousel as strict JSON containing a caption and slide-by-slide headings, body text, and visual descriptions. Builds per-slide image prompts and uses OpenAI (gpt-image-1) to generate a 1024×1536 portrait image for each slide. Sends the generated slide images to Telegram and waits for you to approve or decline posting. If approved, requests per-account upload URLs from PostFast, uploads each slide image to the provided storage URLs, and schedules one PostFast social post per account with the slides in order and the generated caption. Setup Install and enable the PostFast community node (n8n-nodes-postfast) and
Create Zoho Books invoices from email attachments using OpenAI OCR
Quick overview This workflow monitors an IMAP inbox for emails with invoice attachments, uses OpenAI to OCR and extract structured invoice data, looks up customers and tax/currency settings in Zoho Books, and then creates a new Zoho Books invoice with the original attachment included. How it works Triggers when a new email arrives via IMAP. Filters for emails that contain attachments, then splits each attachment into its own item for processing. Normalizes each attachment’s binary data and routes it to OpenAI for OCR based on whether it is a PDF or an image. Fetches taxes, currencies, and active customer contacts from Zoho Books and prepares the data for matching and invoice creation. Sends the OCR text plus Zoho Books tax metadata to OpenAI to validate that the document is a sales invoice and to return invoice and customer details as JSON. Filters out non-invoice attachments, matches the extracted customer to an existing Zoho Books contact (with a configurable fallback), and posts a new invoice to Zoho Books using multipart upload to attach the original file. Setup Add IMAP credentials for the mailbox that receives invoice emails. Add Zoho Books OAuth2 credentials and ensure the c
Send CRM lead outreach emails with Notion, Gmail, Google Drive and OpenAI
Quick Overview This workflow watches a Notion CRM for leads ready to contact, checks Gmail to avoid duplicate outreach, then sends or drafts an email with Google Drive PDF attachments and updates the lead status in Notion, with bounce detection that marks invalid emails (using OpenAI to extract addresses). How it works Triggers when a lead page is updated in a selected Notion CRM database. Validates that the lead’s Email field looks like an email address and searches Gmail Sent for recent messages to that recipient to detect prior outreach. If the lead was already emailed and the current status is safe to overwrite, it updates the Notion lead status to “Emailed.” If the lead was not previously emailed, it downloads two PDF attachments from Google Drive, converts them to Gmail attachments, and either creates a Gmail draft for specific domains (optionally sending a Twilio SMS to a rep) or sends a generic vs personalized Gmail email based on whether a contact name exists. After sending, it waits briefly, searches Gmail for bounce messages mentioning “Address not found,” and updates the Notion record to “INVALID EMAIL” (or sets “Emailed” when the status indicates the lead is in an acti
