Wix API & Third-Party Integrations

Does Wix have API integration?

Yes, in both directions. Your Wix site can call other tools: Velo backend code sends requests to any REST API, with keys kept in Wix’s Secrets Manager rather than in page code. Other tools can call your Wix site: Velo HTTP functions give your site its own API endpoints for webhooks, and Wix’s REST APIs let outside systems read and update your site’s data. Wix events, like a new order, a form submission or a new member, can trigger code the moment they happen.

For simple jobs, an app from the Wix App Market may be enough. When there is no app, or the app doesn’t sync the fields, timing or direction you need, a custom integration is the answer.

 

Wix integrations we’ve built

Integration · what we built · where to read more:

• Firebase Authentication: one account for a Wix website and a US company’s statistics software. Sign-up creates the Firebase user first, then the Wix member; login checks Firebase and signs users into both. Read the Firebase case study

• Google Sheets API: a real-time Ground Sample Distance (GSD) calculator for a US drone services company. The backend opens the right tab for each sensor and reads the values from specific cells; new sensors are added by adding a tab. Read the Google Sheets case study

• External databases: live data from outside databases on a Swiss client’s Wix websites, with search filters, multi-level dropdowns and pagination across thousands of records, plus router pages with clean URLs and their own SEO settings. Read the external database case study

• Trello REST API: a US car-parts store’s Wix orders become formatted Trello cards the moment they’re placed, with every product, variant and price modifier. Read the Trello case study

• Google Maps API: a drone image overlap estimator that reads each photo’s GPS data and draws an overlap heatmap on Google Maps inside a Wix site. Read the overlap estimator case study

• Text-to-speech (browser Speech API): a play, pause and resume audio player for a German news website on Wix. Read the text-to-speech case study

• Payment provider APIs: Tamara, Tabby and Moyasar added as native payment options in Wix checkout. See our Wix eCommerce & checkout service

 

Can Wix integrate with Firebase (login and database)?

Yes. Wix has its own members and CRM, and Firebase has its own users, so they don’t sync on their own. We connect them with Velo: Firebase Authentication stays the single source of truth for logins, and the matching Wix member is created and kept in sync, so one account works on your Wix site and your app. Firestore or Realtime Database data can also be read and written from Wix backend code, for dashboards, member areas or app data shown on the site.

 

Can Wix connect to Airtable or Google Sheets?

Yes. Both have APIs that Wix backend code can call. Typical builds: show sheet or Airtable data on Wix pages, send form submissions or orders into a sheet or base, run a calculator or price list from a spreadsheet your team already edits, or keep a Wix CMS collection in sync with Airtable on a schedule. We cache data where it makes sense, so pages stay fast and you don’t hit the tool’s rate limits.

 

Can Wix integrate with my CRM or accounting tool (HubSpot, Zoho, QuickBooks, Xero)?

Check the Wix App Market first: many CRMs and accounting tools have an app that covers the basics. When it doesn’t, we connect to the tool’s API directly. For example, new form leads or members become HubSpot or Zoho CRM contacts with the right fields and tags, and paid Wix orders become invoices or sales receipts in QuickBooks or Xero. You decide what syncs, in which direction, and when.

 

Can I use an external database with Wix and keep pages SEO-friendly?

Yes. Keep the data in your own system and show it live on Wix, with no copy-paste into the CMS. For listing and detail pages that need to rank, we use Velo router pages: each record gets a clean URL, its own title and meta description, and server-rendered content that search engines and AI crawlers can read. That’s how we built searchable, paginated listings over thousands of external records for a Swiss client.

 

Can you build a private Wix app (Wix Blocks or Wix CLI) for my business?

Yes. Sadique Habibullah is a Wix Marketplace App Developer. A private app packages your integration or custom feature so it can be installed on several Wix sites and updated in one place, which suits agencies and businesses that run more than one site. We use Wix Blocks for widgets and the Wix CLI for full-stack apps with their own dashboard pages and backend. Need custom features on a single site instead? See our Wix Velo development service.

 

How we keep integrations secure and reliable

• API keys and tokens live in Wix’s Secrets Manager and run only in backend code.

• Incoming webhooks are checked before your data is changed.

• Errors are logged and retried, so a short outage at the other tool doesn’t lose data.

• We build and test on a copy of your site before anything touches live data.

• You get short notes on how the integration works and what to do if a key changes.

 

How much does a Wix API integration cost?

Third-party and API integrations start from $500, the same ‘from’ price as our Wix Marketplace profile. Private Wix apps and multi-tool syncs get a fixed quote after the call.

What changes the price: the tool’s API and authentication (a simple API key or OAuth), one-way or two-way sync, how many fields and records, whether you need live data or a scheduled sync, and your deadline.

Wix integration FAQs

Should I use Zapier or Make instead of a custom integration?

For a simple one-way trigger with low volume, Zapier or Make is fine. A custom integration is better when you need live data on your pages, two-way sync, logins, complex field mapping, or high volume without per-task fees.

Will an integration slow down my Wix site?

It shouldn’t. API calls run in backend code, and data that doesn’t change every second is cached. On the drone calculator, results come back in seconds every time the user changes an input.

Does it work on both Wix Editor and Wix Studio sites?

Yes. Velo backend code, HTTP functions and router pages work the same on Wix Editor and Wix Studio sites.

Do I need a Wix Premium plan?

Velo code runs on any Wix site, but a live business site needs a Premium plan for your own domain, and features like payments or paid member areas need the matching plan.

Who owns the code?

You do. It lives in your Wix site’s code files, and keys stay in your own Secrets Manager.

Can you fix an integration someone else built?

Yes. We review the code, fix what’s broken and document it so your team knows how it works.
