Příklady použití [Simple promotional](https://www.bulkgate.com/cs/dokumentace/simple-api/simple-promotional/). Simple API bere příjemce jako jeden řetězec oddělený středníkem - skupiny z adresáře, administrátory a alternativní kanály nabízí až [Advanced API](https://www.bulkgate.com/cs/dokumentace/advanced-api/advanced-promotional/2.0/).

## Více příjemců

`number` je řetězec telefonních čísel oddělených středníkem; všem odejde stejný text.

```http-json
POST /api/1.0/simple/promotional HTTP/1.1
Host: portal.bulkgate.com
Content-Type: application/json

{
	"application_id": 451,
	"application_token": "NKN02TWE6NfBkfl-your-secret-token-Wf05GaqLIWLW4aBj",
	"number": "420777777777;420606606234;420601992992",
	"text": "Spring sale starts today, up to 50 % off."
}
```

## Vlastní odesílatel a Unicode

`gText` odešle kampaň z registrovaného textového odesílatele. `unicode` zapněte vždy, když text obsahuje znaky mimo 7bitovou abecedu - zkrátí zprávu na 268 znaků na díl.

```http-json
POST /api/1.0/simple/promotional HTTP/1.1
Host: portal.bulkgate.com
Content-Type: application/json

{
	"application_id": 451,
	"application_token": "NKN02TWE6NfBkfl-your-secret-token-Wf05GaqLIWLW4aBj",
	"number": "420777777777;420606606234;420601992992",
	"text": "Jarní výprodej právě začal.",
	"sender_id": "gText",
	"sender_id_value": "BulkGate",
	"unicode": true
}
```

## Místní čísla a naplánovaná kampaň

Díky `country` můžete zadat čísla bez mezinárodní předvolby. `schedule` přijímá ISO 8601 nebo unix timestamp.

```http-json
POST /api/1.0/simple/promotional HTTP/1.1
Host: portal.bulkgate.com
Content-Type: application/json

{
	"application_id": 451,
	"application_token": "NKN02TWE6NfBkfl-your-secret-token-Wf05GaqLIWLW4aBj",
	"number": "777777777;606606234",
	"country": "cz",
	"text": "Spring sale starts today, up to 50 % off.",
	"schedule": "2026-09-14T09:00:00+02:00"
}
```

## Ochrana proti duplicitám a tag

`same_text` zahodí zprávu se stejným textem na už obsloužené číslo, `same_number` zahodí každou další zprávu na totéž číslo. `tag` označí kampaň pro pozdější dohledání.

```http-json
POST /api/1.0/simple/promotional HTTP/1.1
Host: portal.bulkgate.com
Content-Type: application/json

{
	"application_id": 451,
	"application_token": "NKN02TWE6NfBkfl-your-secret-token-Wf05GaqLIWLW4aBj",
	"number": "420777777777;420606606234;420601992992",
	"text": "Spring sale starts today, up to 50 % off.",
	"duplicates_check": "same_number",
	"tag": "spring-sale"
}
```
