Overview

What the 44API Zapier integration does for you

The 44API Zapier integration plugs a VAT and tax ID checker into the rest of your tools. When a new customer, order or supplier shows up in another app, Zapier hands the number to 44API and gets back a verdict, so nobody copies numbers into a registry form by hand anymore.

Three results come out of it. First, a checked VAT number on every new B2B customer: with Validate VAT Tax Number, 36 of the 53 supported countries go through an official registry (all 27 EU states included), and the other 17 only get a format and checksum check. Second, a batch verdict on up to 10 numbers in one step with Validate VAT Numbers Batch, handy when a supplier list lands all at once. Third, a whitelist that follows your team: Add IP to Whitelist, Remove IP From Whitelist and List All Whitelisted IPs keep the Cloudflare WAF list in step with who actually needs access.

What Zapier does not do here matters just as much. 44API has no trigger, so a validation result can never start a Zap on its own. The Zap starts in another app (a form, a CRM, a spreadsheet) and 44API always comes second. And for the 17 format-only countries, no company data comes back, only a yes or no on the structure of the number.

Vocabulary

Zapier vocabulary in one minute

Seven words cover everything on this page. Read them once and the rest flows.

Zap
The automation you build in Zapier: one trigger, then one or more actions that run every time the trigger event happens.
Trigger
The event in an app that starts a Zap. Once the Zap is on, Zapier waits for it. 44API has none, so another app fills this role.
Action
What the Zap does once it has started: the step that writes, sends or checks something for you. 44API offers five of them.
Task
The unit Zapier bills: one action that completes successfully. The number on your plan is a count of those and nothing else.
Polling vs instant
Polling: Zapier asks an app for new items on a timer. Instant: the app calls Zapier itself the moment the event happens.
Filter
A step that lets the Zap go on only when what arrived meets the condition you set, and stops it there otherwise.
Search step
A step that looks up something that already exists, so the next steps can use what it found. 44API has one: Find VAT Validation.
Cost

What the 44API Zapier integration really costs

Zapier bills tasks, and only actions count. The trigger never costs a thing, and neither does Zapier looking for new data, however often it checks.

  • Free plan100 tasks a month
  • Free plan Zap size2 steps
  • Premium appNo
  • Cost of the trigger0 tasks

Each 44API action that succeeds is one task, so a Zap that validates a number and then writes the verdict elsewhere uses two. A failed action is not counted. 44API is not a premium app, so it works on the free plan: 100 tasks a month, but Zaps of two steps only. Add a filter, a second action or the Find VAT Validation search and the Zap turns multi-step, which needs a paid plan. The interval grid below applies to the trigger of the other app when that trigger polls.

Connect

Connect 44API to Zapier in 3 steps

  1. 01

    Open Apps and add a connection

    In your Zapier account, open the Apps page and click + Add connection. You need an existing 44API account before you start, since Zapier links an account rather than creating one.

  2. 02

    Find 44API and confirm

    Type 44API in the search box of the dialog, pick it from the list, then click Add connection. A new tab opens on the 44API side, where the rest happens.

  3. 03

    Sign in and grant access

    Sign in to 44API in that tab and grant Zapier access to the account. Back in Zapier, the connection shows up in your list, linked once and reused by every 44API step of every Zap.

First Zap

Your first Zap: check the VAT number of each new customer

GoalEvery new row in a customer sheet gets its VAT number checked by 44API, and the verdict goes back into the row.

  1. 01

    Pick what starts the Zap

    Create a Zap and choose the app and event that start it: here, a new row in the sheet where customers land. 44API cannot start a Zap, so this step always belongs to another app.

  2. 02

    Test the trigger

    Run the trigger test. Zapier brings back the three most recent rows of the connected account, so you map the next steps against a real customer, not a blank.

  3. 03

    Add the 44API action

    Add an action, choose 44API, then Validate VAT Tax Number. Map the country column to Country and the number column, stripped of its prefix, to VAT/Tax Number.

  4. 04

    Write the verdict back

    Add a second action that writes the result back into the row. Two actions make the Zap multi-step, so this needs a paid plan; on the free plan, stop after the 44API step.

  5. 05

    Test, then publish

    Run each step once and read what 44API returned before going further. When the answer looks right, click Publish to switch the Zap on.

Actions

The 5 actions of 44API on Zapier

44API gives you 5 actions. For each one: what it does for you, when to reach for it, and what to watch out for.

1

Add IP to Whitelist

Action

In Zapier“Adds an IP address to the CloudFlare WAF whitelist.”

Puts an IPv4 or IPv6 address on the Cloudflare WAF whitelist from inside a Zap, instead of someone doing it by hand in a dashboard.

When to use it
a new office or server needs access, and the request already arrives through a form or a ticket in another tool.
Watch out
IP Address is required, so a Zap fed an empty value stops at this step.
2

List All Whitelisted IPs

Action

In Zapier“Returns all IP addresses in your whitelist with summary counts.”

Returns every address currently on your whitelist, along with summary counts, as data the next steps can reuse.

When to use it
an access review where the full list gets copied into a sheet or a message, so someone can check who still needs to be on it.
Watch out
this is an action, not a trigger: it only runs when something else starts the Zap, and each successful run counts as a task.
3

Remove IP From Whitelist

Action

In Zapier“Removes an IP address from the CloudFlare WAF whitelist.”

Takes an address off that same Cloudflare WAF whitelist, the mirror image of the previous action.

When to use it
someone leaves the team or a server is retired, and access should close when the record changes in your other tool.
Watch out
pass the exact IPv4 or IPv6 address that was added; the field is required and nothing gets removed without it.
4

Validate VAT Tax Number

Action

In Zapier“Validates a VAT, GST, or tax ID number. 53 countries: 36 with an official registry lookup (all 27 EU states plus GB, NO, CH, RS, IS, IL, CA, AU, NZ) and 17 with format and checksum validation only.”

Checks one VAT, GST or tax ID number and tells you whether it holds up. In 36 countries, including all 27 EU states, the check goes through an official registry; in 17 others it stops at format and checksum.

When to use it
a new B2B customer signs up and the number should be confirmed before the first invoice goes out.
Watch out
the number goes in without its country prefix, and format-only countries return no company data.
5

Validate VAT Numbers Batch

Action

In Zapier“Validates multiple VAT numbers at once (max 10).”

Sends up to 10 VAT numbers to 44API in a single step and returns a verdict for each of them.

When to use it
a supplier list or a spreadsheet export arrives with several numbers that all need checking at the same moment.
Watch out
here every number keeps its country prefix, the opposite of the single check, and a list longer than 10 has to be split first.
Searches

The 44API search step

1 search step looks for data that already exists in 44API, so a later step can use it.

44API has one search step. It sits at the bottom of the action-event list, under the SEARCH heading. Adding it makes the Zap multi-step, so it needs a paid plan.

1

Find VAT Validation

Search

In Zapier“Looks up a VAT number and returns validation result.”

Asks 44API about a VAT number and hands the validation result to the following steps, without writing anything anywhere.

When to use it
a deal moves forward in your CRM and the next step needs to know whether the customer's number is valid before acting.
Watch out
Country Code takes two letters, like DE or FR, and the number goes in without its prefix. There is no find-or-create variant here.

The three settings every search exposes

  1. Successful if no search results are found?
    Left on its default, a search that finds nothing stops the Zap right there. Switched on, the Zap carries on empty-handed.
  2. Create X if it doesn't exist yet?
    This box turns a search into a find-or-create. Find VAT Validation has no such variant, so this search only ever looks.
  3. If multiple search results are found?
    Three ways out: keep the first match (the default), stop the Zap, or hand every match on at once.
When it breaks

When the 44API Zap breaks

Zapier attaches no help article to 44API, so the cases below are the general Zapier limits that hit a validation Zap.

If a Zap stops for a reason not listed here, the Zapier troubleshooting guide walks through the checks to run.

  • Existing records are never checked

    A Zap only reacts to what happens after you switch it on. Customers already in your sheet stay unchecked, and moving that backlog is a separate job.

  • The Zap keeps setting itself off

    If the Zap writes the 44API verdict into the very sheet its trigger watches, it can restart itself again and again and burn through the task count fast.

  • A bulk import gets held back

    When the trigger app suddenly returns a huge batch, after an import or a migration, Zapier's flood protection can hold it back instead of running it all.

  • The same item never runs twice

    On a polling trigger, Zapier keeps track of what it has already seen, so one customer does not start the Zap twice and one check is not billed twice.

FAQ

44API and Zapier: frequent questions

01Is the 44API Zapier integration free?
Yes, on the Zapier side, because 44API is not a premium app and works on the free plan. That plan gives 100 tasks a month and Zaps of two steps: one trigger from another app and one 44API action. Adding Find VAT Validation, a filter or a second action turns the Zap multi-step, and that needs a paid plan. Your 44API account itself is a separate matter, with its own terms on the 44API side.
02How many Zapier tasks does a 44API check use?
One per successful action. Validate VAT Tax Number, Validate VAT Numbers Batch and the three whitelist actions each count as a task when they complete. The trigger from the other app costs nothing, and Zapier looking for new data is free as well. A failed action is not counted. A few apps and actions take more than one task when they complete, so the count per check is not always one.
03Does 44API work in real time with Zapier?
It depends on the app that starts the Zap, since 44API has no trigger of its own. If that app has an instant trigger, it calls Zapier the moment the event happens and the plan interval does not apply. If it polls, Zapier checks on a timer: every 15 minutes on Free, 2 on Professional, 1 on Team and Enterprise. The 44API action then runs as the next step. A Zap built on an instant trigger shows a lightning bolt in the editor.
04What is needed to connect 44API to Zapier?
A 44API account and a Zapier account. In Zapier, open Apps, click + Add connection, search for 44API, confirm with Add connection, then sign in and grant access in the tab that opens. The connection is saved once and reused by every 44API step. If the Zap touches something you do not own, you also need read or write access to it. For a new Zap there is no need to connect again: just pick the account already linked.
05Why does a VAT check fail on a number that looks fine?
Check the prefix first. Validate VAT Tax Number and Find VAT Validation want the number without its country prefix, with the country given separately, as a two-letter code for the search. Validate VAT Numbers Batch wants the reverse, prefix included, and at most 10 numbers. Also keep in mind that for 17 of the 53 countries, 44API only checks format and checksum and cannot return company data. Fix the format first, then rerun the step test.
06What if the 44API operation required is missing?
Then Zapier cannot do it with 44API alone. The integration covers 5 actions and 1 search: single and batch VAT checks, a VAT lookup, and three whitelist actions. There is no trigger, so a validation can never start a Zap by itself. The workable options are to start the Zap from another app and chain 44API after it, or to compare other automation tools before committing. The full list of operations sits in the blocks above.
07Zapier, Make or n8n for 44API?
Decide by criteria, not by brand. Zapier fits when the 5 actions and the search listed here cover the job and you want a short setup. For Make or n8n, first check that a 44API module or node exists, then compare setup effort, how each run is billed, and where the tool is hosted. The right answer is the tool that already covers your exact operation. Keep in mind that the free Zapier plan stops at two steps.
