ProductsBigiHubIntegration API platform
One API. Every provider.
BigiHub gives software companies one stable API for e-invoicing, virtual POS and marketplaces, and maps every request to the provider their customer chooses.
Up to fewer integrations to build and maintain
Up to faster go-live for a new provider
Code changes when a provider switches

01The problem
Why it exists
Every e-invoice integrator, bank POS and marketplace has its own API, auth model and quirks. Software vendors end up writing and maintaining the same integration a dozen times, and every provider change ripples into their product.
Our answer
Clients integrate once against BigiHub's canonical contract. BigiHub resolves the customer's connection, maps the request to the selected provider, runs it asynchronously and reports status, documents and signed webhooks back — the client's request never changes when the provider does.
Built forSoftware companies (ERP, accounting, e-commerce and vertical SaaS vendors) that need to offer many Turkish integrators to their own customers.
02What it does
Everything BigiHub takes off your plate.
One canonical contract
A single versioned REST API with OpenAPI docs; providers can change underneath without touching client code.
E-Invoice and e-Archive
Send, pull, track and fetch PDFs through QNB eFinans, EDM, Mysoft and BirFatura, in UBL-TR 1.2.
Automatic invoice type decision
Leave the type empty and BigiHub checks whether the buyer is a registered e-Invoice user, choosing e-Invoice or e-Archive for you.
Virtual POS
Payments, installments, refunds, voids and card storage across iyzico, Garanti, Ziraat, QNBpay, Posnet and VakıfBank.
Marketplace commerce API
Push products, stock and prices and receive orders from Trendyol, Hepsiburada, n11, Amazon, Pazarama, PttAVM, Çiçeksepeti, Idefix and automotive marketplaces.
Embeddable hosted forms
Drop in an invoice or payment form as an npm React component or a hosted link, secured by short-lived, single-use tokens with server-enforced field locks.
Signed webhooks and tracking
Every meaningful status change is pushed to the client's callback URL as a signed event.
Multi-tenant admin panel
Each company manages connections, encrypted credentials, invoices and webhooks from its own panel.
03How it works
From first step to everyday use.
Get an API key
Sign up and create a company; the panel issues a bearer API key.
Add connections
Pick the integrators your customer uses and store their credentials securely.
Send canonical requests
Call one endpoint per action; BigiHub queues the job and maps it to the chosen provider.
Receive results
Track status, download PDFs and get signed webhooks as each request progresses.

05The value
What changes when you use it.
Integrate once
One contract replaces a separate integration per provider.
Provider freedom
Customers switch or add integrators without code changes on the client side.
Fewer compliance mistakes
e-Invoice versus e-Archive and tax-exemption rules are handled by the platform.
Faster roadmap
New domains like shipping, SMS and email arrive through the same contract.
