Generate alt text for an image URL batch
Send a ready CSV to Alttext.ai to process many image URLs together and surface row errors for review.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Bulk Create Images
Upload and process a CSV of image URLs to generate alt text in bulk.
Why this helps
Processing a large set of generated or stored images one by one creates repetitive work and makes failures harder to spot.
- Process up to 100,000 image URLs in a batch.
- Review invalid rows through returned row errors.
- Keep bulk processing tied to a specific document or image job.
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 submit the supplied image URL CSV to Alttext.ai and report any row errors.
- 4Choose the webhook trigger and arrange for your backend to send the CSV when the batch is ready.
- 5Choose where run reports go, then test with a small real CSV.
