UAE e-invoicing API,
plug and ship.
One REST API to ingest invoices from any system, standardize them, validate them pre-transmission, and submit them through accredited service providers to the Federal Tax Authority. Validation is free. You pay only on submission.

Three steps from your invoice to a cleared FTA reference
Ingest
Send a plain JSON invoice via the REST API. Or push from a prebuilt connector (Zoho, QuickBooks, Xero, Tally, SAP, NetSuite, Dynamics). Or drop a CSV or PDF in the portal.
Standardize & Validate
We map your invoice to PEPPOL PINT AE, then run the full UAE FTA rule set before anything leaves the system: mandatory fields, TRN format, tax math, and routing eligibility. Validation errors come back human-readable, and this step is free. It does not count toward billing.
Submit & Track
The validated invoice is delivered to the Federal Tax Authority through an accredited service provider, the only billable event. Clearance status, FTA reference, and the compliant PDF flow back through the API and via signed webhooks on every state change, so your system stays in sync without polling.
Use the API directly, or connect through what you already have
Three integration paths into the same orchestration engine.
Your code
Call the REST API from any language. Bearer-token auth, idempotent submits, signed webhooks. SDKs available on request.

Prebuilt connectors for Zoho, QuickBooks, Xero, Tally, SAP, NetSuite, and Dynamics. The API powers them under the hood.
For businesses →Custom ERP or in-house
If your system is not on the list, we build the connector for you at no extra charge. The same API, dressed in your stack.
How that works →We include every piece you would otherwise build, host, and maintain
An in-house e-invoicing integration is not one project. It is several. It starts with what an accredited service provider is and only grows from there. Here is what we take off your plate.
On your own
- ✕ Apply for accreditation, then maintain it
- ✕ Map and re-map PEPPOL PINT AE as the rules change
- ✕ Run pre-transmission validation logic yourself
- ✕ Negotiate and stitch in a UAE ASP per route
- ✕ Build retries, dedupe, and webhook signing yourself
- ✕ Carry the penalty risk if an invoice slips
- ✕ Track every FTA rule change in-house
Done for you
- Accredited ASP included, nothing to apply for
- PEPPOL PINT AE mapped for you, updates handled
- Free pre-transmission validation on every invoice
- Multi-ASP routing handled by the orchestration layer
- Idempotent submits, signed webhooks, retries built in
- Validation catches errors before the FTA does
- We track every rule change so you do not have to
Built for two kinds of teams
Whether you are integrating one stack or shipping e-invoicing inside someone else's, the same API does both jobs. New to the mandate? Start with the UAE e-invoicing guide.
Wire UAE e-invoicing into your stack
Your finance team uses your tools. Your developers add one HTTP call. Compliance becomes a property of the system, not a project.
- One REST API for submit, status, void
- Free pre-transmission validation on every call
- Webhooks for cleared, rejected, voided
Ship e-invoicing inside your product, white labeled
Add UAE e-invoicing to the product or service you already sell. White label the dashboard, your customers see your brand, and the accredited provider stays included.
- White label dashboard, your brand
- Multi-tenant API per client
- Free custom connectors for unique stacks
Two things competitors will not give you
Both of these came up first in every conversation with finance and engineering teams evaluating UAE e-invoicing software. Neither shows up in competitors' pricing pages.
Validation is free. Submission is the only billable event.
We separate validation from submission inside the API. Every invoice runs the full FTA rule set first. If it fails validation, it is not sent and you are not charged. Other UAE providers charge per API call or per invoice, whether or not anything reached the FTA. We do not. Your spend tracks successful submissions only.
- Failed validations cost nothing
- Pre-flight any draft invoice for free
- Billing aligns with what actually got submitted
If our connector does not cover your system, we build one. At no extra charge.
A custom POS, an internal ERP, a homegrown billing platform. Send the docs or the schema, and our engineering team writes the connector against the EInvoice Direct API. You pay for the software, not the integration.
- Schema mapping handled end to end
- Reasonable scope, agreed up front in writing
- Maintained as your system or the FTA rules change
- Available for businesses and white-label partners
API questions, answered
Is there a UAE e-invoicing API I can call from my code?
Yes. The EInvoice Direct API is a REST API designed for the UAE FTA mandate. You submit a plain JSON invoice, we standardize it to PEPPOL PINT AE, validate it against the FTA rule set, and submit it through an accredited service provider to the Federal Tax Authority. A clearance reference and a compliant PDF come back in the response.
Are you an accredited service provider yourselves?
No. EInvoice Direct is an orchestration layer built by Massive FZCO. We hold commercial partnerships with multiple accredited UAE service providers, and one of them is included with every plan. Your code talks to a single stable API and we handle the routing under the hood.
How is the API priced? Per call, per invoice, or per submission?
Per successful submission. Every invoice runs through pre-transmission validation first, and the validation step is free. If validation fails, the invoice is not sent to the Federal Tax Authority and you are not billed. The only billable event is a successful submission, so bad invoices cost you nothing.
Do I need to apply for FTA accreditation or join Peppol?
No. An accredited UAE service provider is included with every plan. Your application talks to one API. The accredited provider handles the official network, the FTA reporting, and the format updates.
What does the API actually do?
Five things, in order. Ingest your invoice in plain JSON. Standardize it to PEPPOL PINT AE. Validate it against UAE FTA rules pre-transmission, for free. Submit it through an accredited service provider, the only billable event. Track its clearance status through the API and signed webhooks.
Will the API work with my ERP or accounting system?
Yes. You can integrate the API directly into any system. We also ship prebuilt connectors for Zoho, QuickBooks, Xero, Tally, SAP, NetSuite, and Dynamics, which call the same API under the hood. If your system is not on the list, we build the connector for you at no extra charge.
How do I handle status changes? Polling or webhooks?
Webhooks. Every state transition (validated, submitted, cleared, rejected, voided) fires a signed webhook to your endpoint. Submissions are idempotent by your invoice reference, so safe to retry on network failures. A polling endpoint is also available if your environment cannot receive inbound calls.
Is there a sandbox?
Yes. Sandbox keys are issued alongside live keys. The sandbox mirrors live validation and submission behavior with test FTA references, so you can build and test against realistic responses before you switch to live.
How quickly can a team go live?
Most teams go live within days. The API is designed for fast onboarding, the validation messages are human-readable, and our Dubai-based engineering team is available to unblock during integration.
