Hire a Zapier Developer
Custom Zapier builds for workflows that go beyond drag-and-drop: Code steps, webhooks and API integrations that connect the apps your business runs on.
What a Zapier developer builds
Code by Zapier steps
When the built-in actions are not enough, we write JavaScript or Python Code steps to transform data, run logic and call services.
Code steps keep complex rules inside one Zap instead of spreading them across spreadsheets and manual work.
Webhooks
We use Webhooks by Zapier to receive data from any app that can send it, and to push data to apps that accept it.
That means your tools can talk to each other even when there is no ready-made Zapier trigger or action.
API integrations
If an app has an API, we can connect it, including authentication, pagination and error handling.
We build these as API request steps or custom integrations, so your data moves between systems without copy and paste.
Multi-step builds
Paths, filters, formatters, lookups and storage combined into reliable multi-step Zaps.
Each build is documented, so you know what every step does and what to check if something changes.
When do you need a Zapier developer?
Some workflows need more than drag-and-drop.
If an app has no Zapier connection, or your data needs reshaping before it moves, you need someone who can write code and work with APIs.
A Zapier developer builds custom Zapier integrations with Code steps, webhooks and API calls.
For planning, fixing and everyday Zaps, our Zapier expert service is the right fit.
For custom builds, our developers handle the code while you focus on running your business.

How we work
Filling up the form
First you fill-up the form with all your automation and integration requirements, the platform you want to integrate, & other expectations.
Creating quote
We scope the build, the apps and APIs involved, and send a quote based on the estimated time to complete it.
Getting started
Once you accept the proposal, our developer builds, tests and documents the integration in the agreed time frame.
Zapier developer services
Custom integrations
Connect apps that have no Zapier integration, using webhooks and API requests.
Fix and harden Zaps
Find why complex Zaps fail, fix them and add error alerts so you hear about problems first.
Documentation and handover
Every build comes with notes on how it works, so your team can maintain it.
What do you need built?
Apps without a Zapier connection
Not every app is on Zapier. If it has an API or sends webhooks, we can still connect it.
We handle authentication, requests and responses inside your Zaps.
Your new tool joins the rest of your stack without manual exports.
CRM and lead routing
Leads arrive from forms, ads, landing pages and chat in different formats.
We clean, enrich and route each lead to the right owner and pipeline with Code steps and lookups.
Your CRM and email tools stay in sync without duplicates.
E-commerce data sync
Orders, customers and inventory often live in different systems.
We build integrations that keep store, accounting, fulfilment and support tools in sync.
Including custom logic for things like order tagging, segmentation and high-risk order alerts.
Teams lose hours pulling numbers into reports by hand.
We pull data from your apps through their APIs and send it to sheets, dashboards or chat on a schedule.
Everyone sees the same numbers without anyone copying them.

Zapier developer FAQs
A Zapier developer builds custom automations with Code by Zapier steps, webhooks and API requests, for workflows that standard triggers and actions can’t handle.
If you need Zaps planned, built or fixed with standard apps, hire a Zapier expert. If you need Code steps, webhooks or API work, you need a Zapier developer.
Yes. If your software has webhooks or an API, it can be connected.
JavaScript or Python, the two languages Code by Zapier supports.
Yes, even if one of your app isn’t on Zapier website, you can still use it.
Not all software apps have an existing Zapier connection.
If this is the case we can create a custom integration using APIs and web-hooks between the two applications you want to connect.
We follow a crisp 3-step process for delivering the complete automation project. You can read more about it here.
