FGO API Documentation

Welcome to the FGO Invoicing API v7.0.

Base URLs

Environment	URL
Test	`https://api-testuat.fgo.ro/v1`
Production	`https://api.fgo.ro/v1`

Note: Test and production environments are separate and do not sync.

Getting Started

Create FGO Account
- Test: https://testuat.fgo.ro/inregistrare
- Production: https://www.fgo.ro/inregistrare
Create API User
- Go to FGO Settings → Users
- Generate API user to obtain a Private Key
- Production requires PRO or PREMIUM subscription
Define Registry
- In FGO Settings, verify Registry is defined
- Go to "Serii Documente" tab

Authentication

All API requests require three authentication parameters:

Parameter	Type	Description
`CodUnic`	string	Your company fiscal code (CUI)
`Hash`	string	SHA-1 hash (see Hash Calculation section)
`PlatformaUrl`	string	Root URL of your application

Request Format

All POST requests must send a raw JSON body with the header Content-Type: application/json.

⚠️ Important: application/x-www-form-urlencoded and multipart/form-data are NOT supported. In PHP, passing an array directly to CURLOPT_POSTFIELDS sends form-encoded data and can crash the request — always use json_encode() with the Content-Type: application/json header.

Rate Limits

The API enforces the following rate limits per API user:

Endpoint Category	Rate Limit	Timeout
Invoice/Payment	1 request/second	15 seconds
Articles	1 request/5 seconds (or 1/30s)	Standard

Nomenclatures

Nomenclatures are reference lists of valid values for API fields.

GET /nomenclator/{type}

Retrieve a nomenclature list by type.

Available Nomenclatures

Type	Description
`tara`	Countries
`judet`	Counties
`tva`	VAT rates
`banca`	Banks

Hash Calculation

All API requests require a SHA-1 hash. The hash varies by endpoint.

For Invoice Creation (Emitere)

Use the client name in the hash:

Hash = SHA1(CodUnic + PrivateKey + ClientName)

Example

Parameter	Value
`CodUnic`	2864518
`PrivateKey`	1234567890
`ClientName`	Ionescu Popescu
`Hash`	8C3A7726804C121C6933F7D68494B439463996E2

For Other Invoice Operations

For Anulare, Stornare, Print, Incasare, StergereIncasare:

Hash = SHA1(CodUnic + PrivateKey + InvoiceNumber)

Example

Parameter	Value
`CodUnic`	2864518
`PrivateKey`	1234567890
`InvoiceNumber`	123
`Hash`	SHA1("28645181234567890123")

For Articles

No additional data required:

Hash = SHA1(CodUnic + PrivateKey)

Note: All hashes are uppercase SHA-1. Use a SHA-1 library in your language.
