Automate AltText.ai with Tray.ai
Generate alt text for an image in AltText.ai and start a workflow when AltText.ai sends “Image uploaded”.
What can you do with AltText.ai on Tray.ai?
AltText.ai uses AI to write alt text for images in over 130 languages, improving accessibility and image SEO for websites and online stores. Tray.ai connects to AltText.ai through the HTTP Connector, so your workflows can call the AltText.ai API alongside the rest of your stack.
- When AltText.ai sends “Image uploaded”, write the generated alt text back to your CMS.
- Generate alt text for an image each time a product is added to your online store.
- Scrape a page for images after each site release so new pages get alt text.
- Connects through
- HTTP Connector
- Authentication
- An API key in a request header
- Base URL

Set it up
Connect AltText.ai to Tray.ai
Each step uses AltText.ai's own API details, from its documentation.
Step 1
Save AltText.ai's API key
Save the key as a Tray.ai authentication. The HTTP Client puts it in the request header, read from $.auth. The key stays out of the workflow and out of the logs.
Step 2
Point the HTTP Client at the API
Add an HTTP Client step and use https://alttext.ai/api/v1 as the base URL. Or paste a cURL example from AltText.ai's API docs, and Tray.ai fills in the method, URL, and headers.
Step 3
Start with “List images”
It's one of 14 documented actions, under Images. The response comes back as data the next step can map into your other apps.
Step 4
Start workflows from AltText.ai events
Give AltText.ai the URL of a Tray.ai webhook trigger. “Image uploaded” can then start a workflow, and so can 1 other event.
