API Integration Examples

This guide shows you practical implementation examples for common use cases of the Famulor API.

Basic Integration

Listing Assistants

Before making calls, list available assistants:

async function getAssistants() {
  const response = await fetch('https://app.famulor.de/api/user/assistants', {
    headers: {
      'Authorization': `Bearer ${process.env.FAMULOR_API_KEY}`,
      'Content-Type': 'application/json'
    }
  });
  
  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }
  
  const assistants = await response.json();
  return assistants;
}

// Usage
getAssistants()
  .then(assistants => console.log('Available assistants:', assistants))
  .catch(error => console.error('Error:', error));

Call Integration

Simple Call

async function makeCall(phoneNumber, assistantId, variables = {}) {
  const response = await fetch('https://app.famulor.de/api/user/make_call', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.FAMULOR_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      phone_number: phoneNumber,
      assistant_id: assistantId,
      variables: variables
    })
  });

  const result = await response.json();
  
  if (!response.ok) {
    throw new Error(`API Error: ${result.message}`);
  }

  return result;
}

// Example usage
makeCall('+4915123456789', 123, {
  customer_name: 'Max Mustermann',
  email: 'max@example.com',
  appointment_time: '2024-03-15 14:00'
})
.then(result => {
  console.log('Call started successfully:', result.call_id);
  console.log('Status:', result.status);
})
.catch(error => console.error('Error:', error.message));

CRM Integration Examples

HubSpot Integration

// HubSpot contact to Famulor call
class HubSpotFamulor {
  constructor(hubspotToken, famularToken) {
    this.hubspotToken = hubspotToken;
    this.famularToken = famularToken;
  }

  async getHubSpotContact(email) {
    const response = await fetch(`https://api.hubapi.com/crm/v3/objects/contacts/search`, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${this.hubspotToken}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        filterGroups: [{
          filters: [{
            propertyName: 'email',
            operator: 'EQ',
            value: email
          }]
        }]
      })
    });
    
    const data = await response.json();
    return data.results[0];
  }

  async callHubSpotContact(email, assistantId) {
    try {
      // 1. Retrieve HubSpot contact
      const contact = await this.getHubSpotContact(email);
      
      if (!contact) {
        throw new Error('Contact not found in HubSpot');
      }

      // 2. Famulor call with HubSpot data
      const callResult = await fetch('https://app.famulor.de/api/user/make_call', {
        method: 'POST',
        headers: {
          'Authorization': `Bearer ${this.famularToken}`,
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          phone_number: contact.properties.phone,
          assistant_id: assistantId,
          variables: {
            customer_name: `${contact.properties.firstname} ${contact.properties.lastname}`,
            email: contact.properties.email,
            company: contact.properties.company,
            last_interaction: contact.properties.notes_last_updated
          }
        })
      });

      const result = await callResult.json();
      console.log('Call started for HubSpot contact:', result.call_id);
      
      return result;
    } catch (error) {
      console.error('CRM integration error:', error);
      throw error;
    }
  }
}

// Usage
const integration = new HubSpotFamulor(
  process.env.HUBSPOT_TOKEN,
  process.env.FAMULOR_API_KEY
);

integration.callHubSpotContact('max@example.com', 123);
