Berichtvariabelen

Gebruik variabelen om trapsgewijze berichten te personaliseren met dynamische inhoud zoals namen, URL's en aangepaste waarden.

Overzicht

Variabelen maken het volgende mogelijk:

• Personalisatie: voer namen van ontvangers en rekeningnummers in
• Dynamische URL's: voeg unieke links toe voor elke ontvanger
• URL-verkorting: verkort automatisch lange URL's
• Herbruikbaarheid van sjablonen: één sjabloon, veel gepersonaliseerde berichten

Variabele typen

Typ	Syntaxis	Doel	Voorbeeld
naam	%naam=id%	Tekstvariabelen	Namen, codes, bedragen
url	%url=id%	Volledige URL's	Links, tracking-URL's
korte_url	%short_url=id%	Verkorte URL's	Compacte koppelingen

Variabele syntaxis

Variabelen gebruiken het formaat: %type=id%

• type: Variabel type (name, url, short_url)
• id: unieke identificatie (geheel getal)

Voorbeelden

Hello %name=1%, your code is %name=2%
Visit our website: %url=1%
Quick link: %short_url=1%

Variabelen gebruiken

Stap 1: Variabelewaarden uploaden

Upload variabelewaarden naar de API voordat u berichten verzendt:

Eindpunt:

POST https://restapi.smsbat.com/api/items

Verzoek:

{
  "variables": [
    {
      "id": 1,
      "type": "name",
      "value": "John"
    },
    {
      "id": 2,
      "type": "name",
      "value": "12345"
    },
    {
      "id": 3,
      "type": "url",
      "value": "https://example.com/products"
    },
    {
      "id": 4,
      "type": "short_url",
      "value": "https://example.com/very-long-url-that-needs-shortening"
    }
  ]
}

Stap 2: Bericht met variabelen verzenden

Gebruik geüploade variabele-ID's in uw bericht:

{
  "id": "msg-001",
  "fromName": "YourStore",
  "toPhone": "+380XXXXXXXXX",
  "messageType": "transaction",
  "text": "Hello %name=1%! Your verification code is %name=2%. Visit: %short_url=4%"
}

Resultaat:

Hello John! Your verification code is 12345. Visit: https://sho.rt/abc123

Beste praktijken

Variabele ID's

• ✅ Gebruik opeenvolgende ID's (1, 2, 3, ...)
• ✅ Hergebruik ID's voor bulkberichten met dezelfde variabelen
• ✅ Documentvariabele ID-toewijzing
• ❌ Gebruik geen willekeurige ID's
• ❌ Sla ID-nummers niet over

Variabele waarden

• ✅ Valideer waarden voordat u uploadt
• ✅ Ga op de juiste manier om met speciale tekens
• ✅ Test met randgevallen
• ❌ Neem geen HTML op in naamvariabelen
• ❌ Overschrijd redelijke lengtelimieten niet

URL-variabelen

• ✅ Gebruik short_url voor lange URL's
• ✅ Inclusief trackingparameters
• ✅ Gebruik HTTPS
• ❌ Gebruik geen verdacht uitziende URL's
• ❌ Neem geen gevoelige gegevens op in URL's

Prestaties

• Upload variabelen één keer, stuur meerdere berichten
• Batchvariabele uploads
• Cache van veelgebruikte variabelen
• Ruim periodiek oude variabelen op

Geavanceerde patronen

Bulkpersonalisatie

async function sendBulkPersonalized(recipients) {
  const messages = [];
  const variables = [];
  let varId = 1;

  recipients.forEach((recipient, index) => {
    // Variables for this recipient
    const nameVarId = varId++;
    const orderVarId = varId++;
    const urlVarId = varId++;

    variables.push(
      { id: nameVarId, type: 'name', value: recipient.name },
      { id: orderVarId, type: 'name', value: recipient.orderId },
      { id: urlVarId, type: 'url', value: recipient.trackingUrl }
    );

    messages.push({
      id: `order-${recipient.orderId}`,
      fromName: 'YourStore',
      toPhone: recipient.phone,
      messageType: 'transaction',
      text: `Hi %name=${nameVarId}%! Order %name=${orderVarId}% shipped. Track: %url=${urlVarId}%`
    });
  });

  // Upload all variables
  await uploadVariables(variables);

  // Send all messages
  return await sendBulk(messages);
}

Sjabloonsysteem

class MessageTemplate {
  constructor(template) {
    this.template = template;
    this.varIdCounter = 1;
  }

  create(data) {
    const variables = [];
    let text = this.template;

    // Replace placeholders with variable syntax
    Object.entries(data).forEach(([key, value]) => {
      const varId = this.varIdCounter++;
      variables.push({
        id: varId,
        type: this.getVarType(value),
        value: value
      });

      text = text.replace(`{{${key}}}`, `%${this.getVarType(value)}=${varId}%`);
    });

    return { text, variables };
  }

  getVarType(value) {
    if (value.startsWith('http')) return 'url';
    return 'name';
  }
}

// Usage
const template = new MessageTemplate(
  'Hi {{name}}! Order {{orderId}} shipped. Track: {{trackUrl}}'
);

const { text, variables } = template.create({
  name: 'John',
  orderId: 'ORD-123',
  trackUrl: 'https://example.com/track/ORD-123'
});

await sendWithVariables({ text, variables });

Problemen oplossen

Variabelen niet vervangen

• Controleer of variabelen zijn geüpload voordat ze worden verzonden
• Controleer variabele ID-overeenkomsten in tekst en upload
• Zorg voor de juiste syntaxis: %type=id%
• Valideer dat het type variabele overeenkomt met de waarde

URL-verkorting mislukt

• Controleer of de URL geldig en toegankelijk is
• Controleer of de URL begint met http:// of https://
• Zorg ervoor dat de URL niet al is ingekort
• Probeer url te gebruiken in plaats van short_url

Variabele limiet overschreden

• Neem contact op met de ondersteuning voor variabele limieten
• Hergebruik variabele ID's indien mogelijk
• Ruim oude variabelen op
• Optimaliseer het variabele gebruik
