Overview

What the OnSync Zapier integration actually does

OnSync is a CRM, a shared place where business teams manage customer conversations, contacts and sales follow-up. Connected to Zapier, it can start a Zap when a contact arrives, receive contacts from other tools, and send WhatsApp messages without anyone typing them.

Three outcomes cover most uses. A contact base fed by your forms: a form or a booking tool starts the Zap and Create Contact adds the person to OnSync, so sales stop retyping leads. A WhatsApp message on cue: Send Message writes to a phone number through OnSync, for a confirmation, a reminder or a welcome. Your contacts copied elsewhere: New Contact passes each new OnSync contact to a spreadsheet, a mailing tool or an accounting app.

Now what the app page leaves out. There is no search for OnSync on Zapier: a Zap cannot check whether a contact already exists before creating it, so the same person can land twice. There is no action to update or delete a contact either; the integration only creates. And both actions need a phone number: a source that does not carry one cannot feed them.

The trigger is also a polling trigger, so a new contact does not move instantly. If you are still weighing tools, start with the Zapier review.

Vocabulary

Zapier vocabulary in one minute

Eight words come back throughout this page. Here they are in plain English.

Zap
The automation you build on Zapier: one trigger, then one or more actions that run every time the trigger event happens.
Trigger
The event in an app that starts the Zap. Once the Zap is on, Zapier waits for it. OnSync has one: a new contact.
Action
What the Zap does once started: the step that writes, sends or moves something for you, such as creating an OnSync contact.
Task
The unit Zapier bills: one action your Zap completes successfully. The count on your plan is a count of those.
Polling trigger
A trigger Zapier checks on a timer: it asks the app for new items at a fixed interval and keeps what it has not seen before.
Instant trigger
A trigger the app reports itself, calling Zapier the moment the event happens. OnSync has none on Zapier.
Filter
A step that lets the Zap go on only when what arrived meets your condition, and stops it quietly otherwise.
Multi-step Zap
Any Zap beyond one trigger and one action. A second action, a filter or a search makes one, and it then needs a paid plan.
Cost

What an OnSync Zap really costs

The New Contact trigger never costs a task, however often Zapier checks OnSync. What you pay for is each action that succeeds: one contact created, one task; one WhatsApp message sent, one task.

  • New Contact trigger0 task
  • Create Contact, Send Message1 task each when it succeeds
  • Free plan100 tasks a month, 2-step Zaps
  • Premium appNo, OnSync runs on the free plan

A Zap that creates a contact and then messages it uses two tasks per person. A message that fails is not counted. OnSync is not a premium app, so the free plan works: 100 tasks a month, unlimited Zaps, two steps per Zap, and a check every 15 minutes for New Contact. That last point matters: on the free plan, a welcome message can leave up to 15 minutes after the contact appears. A filter or a second action makes the Zap multi-step, which needs a paid plan.

Connect

Connect OnSync to Zapier in 3 steps

  1. 01

    Open your connections

    In your Zapier account, open the Apps page and click + Add connection. A connection is your OnSync account linked to Zapier once, then reused by every Zap that uses OnSync.

  2. 02

    Find OnSync

    Type OnSync in the search box of the dialog, pick it, then click Add connection. You need an existing OnSync account here, so have the login of the right workspace ready.

  3. 03

    Sign in and grant access

    Sign in to OnSync in the tab that opens and grant Zapier access. Pick an account that can read and create contacts, including contacts other people on the team own.

First Zap

Your first OnSync Zap

GoalLog every new OnSync contact in a spreadsheet, then greet it on WhatsApp through OnSync.

  1. 01

    Pick the trigger

    Start a new Zap, choose OnSync as the app and New Contact as the event, then select the OnSync connection from the previous section.

  2. 02

    Test on a real contact

    Run the test. Zapier brings back the three most recent contacts of the connected account, so the next steps are mapped on a real person, not a placeholder.

  3. 03

    Add the spreadsheet row

    Add the spreadsheet app as the first action and map what OnSync sent into the columns. Test this step and check the new row before going on.

  4. 04

    Add the WhatsApp message

    Add OnSync again with Send Message. Map the contact's number into Phone Number, country code included. Two actions make this a multi-step Zap, so it needs a paid plan.

  5. 05

    Test, then publish

    Test the message on your own number first and read what came back. When it looks right, publish the Zap. Each new contact then costs two tasks.

Triggers

The OnSync trigger

1 event starts a Zap when something happens in OnSync. Zapier checks for them at the interval your plan allows.

1

New Contact

Polling trigger

In Zapier“Triggers when there's a new contact.”

Starts your Zap whenever a new contact shows up in your OnSync account, and hands that contact to the steps that follow. It is the way to let the rest of your tools know someone new has entered the CRM.

How it fires
Zapier goes and looks at regular intervals, and how often depends on your plan: every 15 minutes on the free one.
When to use it
a sales team wants every new OnSync contact copied into the mailing tool used for its newsletter.
Watch out
never pair it with Create Contact in the same Zap, or each new contact will create another one.
Actions

The 2 OnSync actions

OnSync gives you 2 actions. For each one: what it does for you, when to reach for it, and what to watch out for.

1

Create Contact

Action

In Zapier“Creates a new contact in your account.”

Adds a new contact to your OnSync account from whatever started the Zap: a form, a booking, a payment.

When to use it
leads from a website form should land in OnSync without a salesperson retyping them.
Watch out
First Name and Phone Number are required, and with no search available the Zap cannot check for duplicates first.
2

Send Message

Action

In Zapier“Send a message to a whatsapp number through OnSync”

Sends a WhatsApp message to a phone number through OnSync, with the text you compose from earlier steps.

When to use it
a customer books an appointment and should get a confirmation on WhatsApp right after the Zap runs.
Watch out
Phone Number is required and must include the country code, otherwise the step cannot reach anyone.
When it breaks

When an OnSync Zap breaks

Zapier attaches no help article to OnSync, so no app-specific error is on record. What breaks here comes from the required fields and from the limits every Zap shares.

Most of these do not show up on day one. They appear as a contact created twice, a message that never left, or a task count draining faster than planned. When one hits, the Zapier troubleshooting page is the next stop.

  • A phone number without its country code

    Send Message needs the recipient's number with the country code. A source that stores local numbers only will make the step fail on every run.
  • The contact loop

    New Contact plus Create Contact in OnSync is a Zap writing where its own trigger watches. Each contact creates a new one, which starts the Zap again and burns tasks.
  • Duplicates on the way in

    There is no OnSync search on Zapier, so Create Contact cannot check first. If the same person fills your form twice, OnSync gets two contacts.
  • Old contacts are never picked up

    A Zap only reacts to what happens after it is switched on. Contacts already in OnSync when you publish will not start it; moving them is a separate job.
  • A bulk import gets held back

    When a trigger suddenly returns a huge batch, after a bulk import or a migration, Zapier's flood protection can hold the runs back instead of firing them all.
  • The same contact twice? Not from the trigger

    Zapier keeps track of what it has already seen on a polling trigger, so one OnSync contact does not start the Zap twice. Duplicates come from the source.

FAQ

OnSync Zapier integration: frequent questions

01Is the OnSync Zapier integration free?
Yes. OnSync is not a premium app, so it works on the free Zapier plan: 100 tasks a month, unlimited Zaps, and a check for new contacts every 15 minutes. The catch is the two-step limit. A Zap such as a form that creates an OnSync contact fits. A Zap that creates a contact and then sends it a WhatsApp message has two actions, so it is multi-step and needs a paid plan. The same goes for any filter you add.
02How many tasks does an OnSync Zap use?
The trigger is free: Zapier checking OnSync for new contacts never costs a task. Each action that succeeds costs one. Creating a contact is one task, sending a WhatsApp message is another, so a Zap doing both uses two tasks per person. An action that fails, for example because the phone number is missing, is not counted. The real risk is a loop: New Contact feeding Create Contact in the same account keeps creating contacts and eats through the task count.
03Is the OnSync integration real time?
No. New Contact is a polling trigger: Zapier asks OnSync for new contacts at regular intervals and keeps only the ones it has not seen. The interval depends on your plan: 15 minutes on Free, 2 minutes on Professional, 1 minute on Team and Enterprise. On paid plans you can change it and run a check by hand from the editor. For a welcome message built on New Contact, count on that interval.
04What does it take to connect OnSync to Zapier?
An existing OnSync account and a Zapier account. From the Apps page in Zapier, click + Add connection, search for OnSync, click Add connection, sign in to OnSync in the tab that opens and grant access. Use an account that can read and create contacts, including those owned by teammates. Before building, check the data you will send: both actions need a phone number, and Send Message wants it with the country code.
05Why does OnSync end up with duplicate contacts?
Because OnSync has no search on Zapier. Create Contact always creates; it cannot look up whether the person is already there first. If the same lead submits your form twice, or two tools feed the same OnSync account, you get two contacts. Keep one source per Zap, and if your form tool can block repeat entries, use that. Never chain New Contact into Create Contact on the same account: that Zap triggers itself and keeps adding contacts.
06What if the OnSync operation you need is not listed?
Then the Zapier editor does not offer it, on any plan. For OnSync, Zapier offers New Contact, Create Contact and Send Message, nothing more: no update, no delete, no search. The usual approach is to keep the missing step in the tool that handles it best, such as a spreadsheet for tracking or your form tool for deduplication, and let OnSync do what it does on Zapier. This list was read from the Zapier app page in October 2026.
07Zapier, Make or n8n for OnSync?
Choose on criteria, not on a ranking. Coverage first: on Zapier, OnSync gives one polling trigger and two actions, with no search and no update, so check whether the other tool's catalog covers the step your flow needs. Then volume: on Zapier the trigger is free, each contact created or message sent is a task, and anything past two steps needs a paid plan. Count your new contacts and messages for a month, then compare that with the pricing model of each tool.
