Generate descriptions from image file uploads
When a workflow has an image file rather than a public URL, send its supported base64 data for description generation.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create Image
Add an image and generate its alt text.
Why this helps
An image that is available only as a file may need extra handling before its description can be generated.
- Use a base64-encoded file upload when supported inputs are available.
- Generate a description without relying on a public image URL.
- Keep file-based image processing in the same workflow.
Setup
Build it in a few focused steps.
- 1Connect ActiveMerge and Alttext.ai once in the Notis portal.
- 2Create an automation in Notis or tell Notis what outcome you want from any channel.
- 3In one instruction, ask Notis to create an image using the supplied base64-encoded file and return its alt text.
- 4Choose the webhook trigger and arrange for your backend to send the supported file data.
- 5Choose where run reports go, then test with one real image file.
Questions about this workflow
Can Create Image accept a file upload?
Yes. The action supports a URL or a base64-encoded file upload.
Can a normal file path be submitted?
The described input is a base64-encoded file, so provide supported file data rather than assuming a local path can be read.
