Trigger

Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Update Image by Asset ID
Update an image’s alt text and metadata; its URL cannot be changed.
Why this helps
Image descriptions can become stale as the content around them changes.
- Update an existing record using its asset ID.
- Use page topic context to inform the requested change.
- Keep image metadata aligned with content updates.
Setup
Build it in a few focused steps.
- 1Connect Ahrefs and Alttext ai once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis in plain language from any channel.
- 3In one instruction, ask Notis to use the Ahrefs page context and update the specified Alttext ai asset with the requested alt text or metadata.
- 4Pick the notis_webhook trigger and choose where run reports go.
- 5Test with one real asset ID and review the proposed update details.
Questions about this workflow
Can this update an image URL?
No. Alttext ai does not allow the URL of an existing image to be updated with this action.
Does the workflow decide on a new alt text by itself?
The instruction should specify the intended change and provide the page context. Review the result for accuracy before relying on it.
