Webhooks

Configure and manage webhooks to receive real-time notifications about memory events

Overview

Webhooks enable real-time notifications for memory events in your Mem0 project. Webhooks are configured at the project level, meaning each webhook is tied to a specific project and receives events solely from that project. You can configure webhooks to send HTTP POST requests to your specified URLs whenever memories are created, updated, deleted, or categorized.

Managing Webhooks

Create Webhook

Create a webhook for your project. It will receive events only from that project:

Python

import os
from mem0 import MemoryClient

os.environ["MEM0_API_KEY"] = "your-api-key"

client = MemoryClient()

# Create webhook in a specific project
webhook = client.create_webhook(
    url="https://your-app.com/webhook",
    name="Memory Logger",
    project_id="proj_123",
    event_types=["memory_add", "memory_categorize"]
)
print(webhook)

const { MemoryClient } = require('mem0ai');
const client = new MemoryClient({ apiKey: 'your-api-key'});

// Create webhook in a specific project
const webhook = await client.createWebhook({
    url: "https://your-app.com/webhook",
    name: "Memory Logger",
    projectId: "proj_123",
    eventTypes: ["memory_add", "memory_categorize"]
});
console.log(webhook);

{
  "webhook_id": "wh_123",
  "name": "Memory Logger",
  "url": "https://your-app.com/webhook",
  "event_types": ["memory_add"],
  "project": "default-project",
  "is_active": true,
  "created_at": "2025-02-18T22:59:56.804993-08:00",
  "updated_at": "2025-02-18T23:06:41.479361-08:00"
}

Get Webhooks

Retrieve all webhooks for your project:

Python

# Get webhooks for a specific project
webhooks = client.get_webhooks(project_id="proj_123")
print(webhooks)

// Get webhooks for a specific project
const webhooks = await client.getWebhooks({projectId: "proj_123"});
console.log(webhooks);

[
    {
        "webhook_id": "wh_123",
        "url": "https://mem0.ai",
        "name": "mem0",
        "owner": "john",
        "event_types": ["memory_add"],
        "project": "default-project",
        "is_active": true,
        "created_at": "2025-02-18T22:59:56.804993-08:00",
        "updated_at": "2025-02-18T23:06:41.479361-08:00"
    }
]

Update Webhook

Update an existing webhook’s configuration by specifying its webhook_id:

Python

# Update webhook for a specific project
updated_webhook = client.update_webhook(
    name="Updated Logger",
    url="https://your-app.com/new-webhook",
    event_types=["memory_update", "memory_add"],
    webhook_id="wh_123"
)
print(updated_webhook)

// Update webhook for a specific project
const updatedWebhook = await client.updateWebhook({
    name: "Updated Logger",
    url: "https://your-app.com/new-webhook",
    eventTypes: ["memory_update", "memory_add"],
    webhookId: "wh_123"
});
console.log(updatedWebhook);

{
  "message": "Webhook updated successfully"
}

Delete Webhook

Delete a webhook by providing its webhook_id:

Python

# Delete webhook from a specific project
response = client.delete_webhook(webhook_id="wh_123")
print(response)

// Delete webhook from a specific project
const response = await client.deleteWebhook({webhookId: "wh_123"});
console.log(response);

{
  "message": "Webhook deleted successfully"
}

Event Types

Mem0 supports the following event types for webhooks:

• memory_add: Triggered when a memory is added.
• memory_update: Triggered when an existing memory is updated.
• memory_delete: Triggered when a memory is deleted.
• memory_categorize: Triggered when a memory is categorized.

Webhook Payload

When a memory event occurs, Mem0 sends an HTTP POST request to your webhook URL with the following payload:

Memory add/update/delete payload:

{
    "event_details": {
        "id": "a1b2c3d4-e5f6-4g7h-8i9j-k0l1m2n3o4p5",
            "data": {
            "memory": "Name is Alex"
            },
        "event": "ADD"
    }
}

Memory categorize payload:

{
    "event_details": {
        "event": "CATEGORIZE",
        "memory_id": "a1b2c3d4-e5f6-4g7h-8i9j-k0l1m2n3o4p5",
        "categories": ["hobbies", "travel"]
    }
}

Best Practices

1. Implement Retry Logic: Ensure your webhook endpoint can handle temporary failures.
2. Verify Webhook Source: Implement security measures to verify that webhook requests originate from Mem0.
3. Process Events Asynchronously: Process webhook events asynchronously to avoid timeouts and ensure reliable handling.
4. Monitor Webhook Health: Regularly review your webhook logs to ensure functionality and promptly address delivery failures.
