M2M Session List

Overview

This endpoint returns a paginated list of chat sessions for a site. Use it to:

Retrieve conversation history for a user
Track session activity over time
Monitor which sessions have active conversations
Recover session IDs for follow-up questions

A session groups messages from a single conversation context. You can have multiple sessions per user (e.g., one per channel or topic).

Authentication

Requires API key in the X-API-Key header:

X-API-Key: <YOUR_API_KEY>

Query parameters

string

Filter results to sessions with this user email. Optional.

integer

Maximum number of sessions to return. Default: 50. Maximum: 500.

integer

Number of sessions to skip (for pagination). Default: 0.

Implementation tips

Pagination

For sites with many sessions, use pagination to avoid large responses:

async function getAllSessions(siteId, email = null) {
  const allSessions = [];
  let offset = 0;
  const limit = 100;
  let hasMore = true;

  while (hasMore) {
    const params = new URLSearchParams({ limit, offset });
    if (email) params.append("email", email);

    const response = await fetch(
      `https://api.uppzy.com/api/v1/m2m/sites/${siteId}/sessions?${params}`,
      {
        headers: {
          "X-API-Key": process.env.UPPZY_API_KEY,
        },
      }
    );

    const data = await response.json();
    allSessions.push(...data.sessions);

    hasMore = allSessions.length < data.pagination.total;
    offset += limit;
  }

  return allSessions;
}

Finding a session by email

Retrieve all sessions for a user:

async function getSessionsForUser(siteId, email) {
  const response = await fetch(
    `https://api.uppzy.com/api/v1/m2m/sites/${siteId}/sessions?email=${encodeURIComponent(email)}`,
    {
      headers: {
        "X-API-Key": process.env.UPPZY_API_KEY,
      },
    }
  );

  const data = await response.json();
  return data.sessions;
}

// Usage
const sessions = await getSessionsForUser(siteId, "user@example.com");
console.log(`User has ${sessions.length} conversations`);

// Find the most recent active session
const activeSession = sessions
  .filter((s) => s.closed_at === null)
  .sort((a, b) => new Date(b.updated_at) - new Date(a.updated_at))[0];

if (activeSession) {
  // Use this session for follow-up questions
  console.log(`Latest session ID: ${activeSession.id}`);
}

Analytics: session activity

Analyze session patterns:

function analyzeSessionActivity(sessions) {
  const stats = {
    totalSessions: sessions.length,
    activeSessions: sessions.filter((s) => s.closed_at === null).length,
    closedSessions: sessions.filter((s) => s.closed_at !== null).length,
    avgMessagesPerSession:
      sessions.reduce((sum, s) => sum + s.message_count, 0) /
      sessions.length,
    mostActiveSession: sessions.reduce((max, s) =>
      s.message_count > max.message_count ? s : max
    ),
  };

  return stats;
}

Session timeout strategy

Manually close stale sessions using the session close endpoint:

async function closeStaleSession(siteId, sessionId) {
  const response = await fetch(
    `https://api.uppzy.com/api/v1/m2m/sites/${siteId}/chat/session/close`,
    {
      method: "POST",
      headers: {
        "X-API-Key": process.env.UPPZY_API_KEY,
        "Content-Type": "application/json",
      },
      body: JSON.stringify({
        session_id: sessionId,
      }),
    }
  );

  return response.json();
}
