AltTextLab Zapier integrationAutomate AltTextLab with Zapier.

The AltTextLab Zapier integration gives you 0 triggers, 1 action and 0 searches. One move, done well: hand it an image link and it writes the alt text. The catch is that something else has to start the Zap, and the image has to be public.

Overview

What the AltTextLab Zapier integration actually does

It lets another app send an image address to AltTextLab and get back a written description of that picture, ready for the alt attribute of a web page. No copy and paste, no tab switching. Zapier carries the link in, AltTextLab answers with text, and Zapier carries the text out to wherever you keep it.

Three results you can expect from it, all built on the single action Generate Alt Text:

A filled description column. A content team logs product photos in a spreadsheet. Each new row with an image link comes back with its alt text in the next column, so nobody writes descriptions by hand on launch day.

A cleaner image library. A marketing team that drops visuals into a shared folder can get a draft description for each file the moment its public link exists, then review it instead of starting from a blank field.

Accessibility work that keeps pace. When a site adds pictures every week, the backlog of empty alt fields grows quietly. Plugging the action into the step where images are published stops that pile from forming in the first place.

What Zapier does not do here matters just as much. AltTextLab has no trigger on Zapier, so it never starts a Zap on its own: another app has to. It has no search either, so you cannot look up a description it wrote earlier. And it only reads images reachable by anyone, without a login. Anything behind a password or a firewall will fail.

Comparing tools? The same app also has an AltTextLab Make integration, and the Make vs Zapier comparison puts the two platforms side by side.

Vocabulary

Zapier words in one minute

Seven terms come back on this page. Here they are in plain English.

Zap
The automation you build in Zapier: one trigger, then one or more actions that run each time that trigger event happens.
Trigger
The event in an app that starts the Zap. Once the Zap is switched on, Zapier sits and waits for it to happen.
Action
What the Zap does after it starts: the step that writes, sends or moves something on your behalf. Generate Alt Text is one.
Task
The unit Zapier bills. One task equals one action your Zap completes successfully, and your plan counts those.
Polling vs instant trigger
A polling trigger is checked by Zapier on a timer. An instant trigger is reported by the app itself the moment the event happens.
Filter
A step that lets the Zap continue only when the incoming data meets a condition you set. Otherwise the run stops there.
Connection
Your account of an app, linked to Zapier once, then reused by every step that talks to that same app.
Cost

What it really costs you

Short version: AltTextLab is not a premium app, so it works on the free plan. Each description it writes costs one task.

  • TriggerFree, never counted
  • Generate Alt TextOne task per success
  • Free plan100 tasks a month, two steps per Zap
  • Premium appNo

The trigger never costs a task, however often Zapier checks for new data. Only a completed action is billed, and an action that fails is not counted. The free plan gives you 100 tasks a month, unlimited Zaps, and a check every 15 minutes on polling triggers. Its quiet limit: a free Zap has two steps, one trigger and one action. Add a filter (say, to skip rows without a link) and the Zap becomes multi-step, which needs a paid plan. A Zap with three actions uses three times more tasks than a one-action Zap.

Connect

Connect AltTextLab to Zapier in three steps

  1. 01

    Open your connections

    In Zapier, go to the Apps page of your account and click + Add connection. You need an AltTextLab account before you start, otherwise there is nothing to link.

  2. 02

    Find AltTextLab

    Type the app name in the dialog that opens, pick AltTextLab from the results, then click Add connection. A new browser tab opens on the AltTextLab side.

  3. 03

    Sign in and allow access

    Log in to AltTextLab in that tab and grant Zapier access to the account. The connection now shows on your Apps page and every future Zap can reuse it without asking again.

First Zap

Your first Zap: alt text for every new image row

GoalEach new row with an image link in a sheet gets its alt text logged in a review sheet automatically.

  1. 01

    Build: pick what starts it

    Create a Zap and choose the app that holds your image links as the trigger. AltTextLab cannot start a Zap, so this first card always belongs to another tool.

  2. 02

    Test the trigger

    Run the test. Zapier brings back the three most recent items from the connected account, so you map fields on a real row instead of a made-up one.

  3. 03

    Add Generate Alt Text

    Add an action, pick AltTextLab, then Generate Alt Text. Drop the image link from the trigger into the Image url field. Accepted formats: JPG, PNG, WebP, SVG, AVIF.

  4. 04

    Send the text back

    Add a step that logs the description in a separate review sheet, never the one the trigger watches. This third card makes the Zap multi-step, so it calls for a paid plan.

  5. 05

    Test, then publish

    Run each step once and read what came back. If the description reads well on a real image, click Publish to switch the Zap on for good.

Actions

The AltTextLab action

AltTextLab gives you 1 action. For each one: what it does for you, when to reach for it, and what to watch out for.

1

Generate Alt Text

Action

In Zapier“Generates alt text for an image using AI”

Give it the address of a picture and it returns a written description, produced by AI, that you can paste straight into an alt attribute or a media library field.

When to use it
right after a step that produces a fresh image link, such as a new product row or a newly shared file.
Watch out
the image must be public and in JPG, PNG, WebP, SVG or AVIF, or the step fails.
When it breaks

When it breaks

Zapier links no help article to AltTextLab, so the known trouble spots are the general ones, plus the public-link rule above.

Most failures here come from the setup around the action, not the action itself. Four cases cover nearly everything you will run into.

  • Old images are ignored

    A Zap only reacts to what happens after you switch it on. Images already sitting in your sheet or folder are never picked up, and clearing that backlog is a separate job.

  • The Zap feeds itself

    If you write the alt text back into the same place the trigger watches, each update can start the Zap again. It loops, and your task count drains fast.

  • A bulk upload gets held back

    Importing hundreds of images at once can make the trigger return a huge batch. Zapier's flood protection may hold it back rather than run every item.

  • The same row will not run twice

    On a polling trigger, Zapier keeps track of the rows it has already seen, so the same row never starts the Zap a second time.

FAQ

AltTextLab Zapier integration: common questions

01Is the AltTextLab Zapier integration free?
Yes, on the Zapier side. AltTextLab is not a premium app, so it runs on the free plan, which includes 100 tasks a month and unlimited Zaps. The limit to keep in mind is structure: a free Zap holds one trigger and one action, nothing more. If you want to write the description back into a sheet as a third step, or add a filter to skip empty rows, you move to a multi-step Zap, and that needs a paid plan. Whatever AltTextLab itself charges is a separate question this page does not cover.
02How many tasks does it use?
One task per description that comes back successfully. The trigger that starts the Zap is never billed, and neither is Zapier checking for new rows or files, however often it looks. If Generate Alt Text fails, for example because the image link is private, that run is not counted against your plan. Each extra action you add after it counts on its own, so a Zap that generates the text and then adds a row to a sheet uses two tasks per image. Plan for that when you size your monthly volume.
03Is it real time?
That depends entirely on the trigger, because AltTextLab has none. The app that starts the Zap decides the timing. If its trigger is instant, the app tells Zapier the moment something happens and no plan interval applies. If it is a polling trigger, Zapier checks on a timer: every 15 minutes on Free, every 2 minutes on Professional, every minute on Team and Enterprise. Look for the lightning bolt in the editor to know which kind you picked. AltTextLab then runs as soon as its step is reached.
04What does it take to connect AltTextLab?
An AltTextLab account, and that is about it. From the Apps page in Zapier, click + Add connection, search for AltTextLab, sign in in the tab that opens and grant access. The connection is then reused by every Zap that calls the app. On the content side, plan for images hosted at a public address. The single required field is the image URL, and if that link sits behind a login or a firewall, the action cannot read the picture and returns nothing useful.
05Why does Generate Alt Text fail on some images?
Usually because the link is not public or the format is not supported. The action reads the image from its address, so a file in a private drive, a preview link that expires, or a page that asks for a password will not work. The accepted formats are JPG, PNG, WebP, SVG and AVIF; anything else, such as a GIF or a PDF, falls outside that list. Test with one image you know is public first, then check what the trigger app actually sends in the field.
06What if the operation needed is not available?
Then the honest answer is that Zapier does not offer it for this app. AltTextLab exposes exactly one action and no trigger or search, so things like listing past descriptions or reacting to activity inside AltTextLab are out of reach. A common workaround is to store each result in a sheet or a database as a later step, so you keep your own history. For anything beyond that, compare what the same app offers on another platform before building around a gap.
07Zapier, Make or n8n for AltTextLab?
It depends on your criteria rather than on a winner. With a single action, the app behaves the same everywhere: an image link in, a description out. What changes is the frame around it. On Zapier, the free plan stops at two steps and bills one task per action. How Make and n8n bill and chain steps is outside this page, so check those terms against your own volume. If your team already runs one of these tools, staying there usually costs less effort than moving for one action.
