Connectors

Webhooks

HTTP webhooks allow external systems to trigger your agents via HTTP requests. They support JSON, form data, and file uploads.

Inbound Mode

Fire-and-forget triggers for asynchronous agent runs. The webhook returns immediately with run IDs while agents process in the background.

Setup Instructions

Create the connector

Open your agent, click Add inbound connector in the Connector Flow, then Create New Connector and select HTTP Webhook.

Select Inbound (Fire & Forget) and copy credentials

Choose the mode and click Create. The detail drawer opens automatically with the Webhook URL and Secret in the Configuration section. To view them later, hover over the connector in the Connector Flow and click the Eye icon.

Send requests

Send requests from your application to the URL, passing the secret in the X-Connic-Secret header.

How Inbound Works

When an inbound webhook receives a request, it immediately queues the agent run and returns a response with the run IDs. The agent processes in the background. Best for background processing, high-volume ingestion, and event-driven architectures.

Response Format

response.json

{
  "status": "ok",
  "dispatched_to": 2,
  "run_ids": [
    "550e8400-e29b-41d4-a716-446655440000",
    "550e8400-e29b-41d4-a716-446655440001"
  ]
}

Sending Requests

Webhooks accept both GET and POST requests with various content types.

JSON Requests

The most common way to trigger webhooks. Send a POST request with a JSON body (application/json). The entire JSON payload is passed to your agent as input.

terminal

curl -X POST <webhook-url> \
  -H "Content-Type: application/json" \
  -H "X-Connic-Secret: <your-secret-key>" \
  -d '{
    "prompt": "Analyze this data",
    "data": {"key": "value"}
  }'

Form Data Requests

Useful for simple integrations or when your source system sends form data (application/x-www-form-urlencoded). Each form field becomes a key-value pair in the payload.

terminal

curl -X POST <webhook-url> \
  -H "X-Connic-Secret: <your-secret-key>" \
  -F "message=Process this invoice" \
  -F "customer_id=12345"

GET Requests

For simple triggers, you can use GET requests with query parameters. All query parameters (except secret) are passed to the agent.

terminal

curl "<webhook-url>?secret=<your-secret-key>&prompt=hello"

Get Your Webhook URL & Secret

The webhook URL includes your webhook_id, and theX-Connic-Secret is generated when you create the connector.

Open your agent's detail page in the Agents section
Add a webhook connector via the + button on the connector flow, or select an existing one
Click the eye icon on the connector to open its details
Copy the Webhook URL and Secret from the connector details

File Uploads

Send files to your agents using multipart/form-data. Files are passed directly to the LLM for analysis.

Files are automatically extracted and sent to the model as inline data:

terminal

curl -X POST <webhook-url> \
  -H "X-Connic-Secret: <your-secret-key>" \
  -F "instructions=What is the total of this invoice?" \
  -F "file=@/path/to/invoice.pdf"

You can upload multiple files in a single request:

terminal

curl -X POST <webhook-url> \
  -H "X-Connic-Secret: <your-secret-key>" \
  -F "message=Compare these two documents" \
  -F "file1=@document1.pdf" \
  -F "file2=@document2.pdf"

Supported File Types

Images

JPEG, PNG, GIF, WebP, HEIC/HEIF

Documents

PDF, Plain text, CSV, HTML, Markdown

File size limit: Maximum 10 MB per file.

Authentication

Secure your webhooks with secret-based authentication.

Providing the Secret

Each webhook has a unique secret key generated when created. You can provide it in three ways:

X-Connic-Secret Header (Recommended) - Most secure, secret is in headers
Authorization: Bearer Header - Standard OAuth-style bearer token
Query Parameter (?secret=...) - Less secure, visible in logs

terminal

# Using X-Connic-Secret header (recommended)
curl -X POST <webhook-url> \
  -H "X-Connic-Secret: <your-secret-key>" \
  -d '{"message": "hello"}'

# Using Authorization: Bearer header
curl -X POST <webhook-url> \
  -H "Authorization: Bearer <your-secret-key>" \
  -d '{"message": "hello"}'

# Using query parameter (less secure)
curl -X POST "<webhook-url>?secret=<your-secret-key>" \
  -d '{"message": "hello"}'

Error Responses

401

Invalid secret key

The provided secret doesn't match. Check your authentication.

404

Webhook not found

The webhook URL doesn't exist. Check the URL is correct.

400

Outbound-only webhook

This webhook is configured for outbound only and cannot be triggered.

Outbound Mode

Deliver agent results to external destinations. When agents complete, results are POSTed to your configured URL.

Setup Instructions

Set up an endpoint

Create an endpoint on your server that can receive POST requests.

Create the connector

Open your agent, click Add outbound connector, then Create New Connector and select HTTP Webhook.

Configure and create

Choose Outbound mode, enter the destination URL where Connic should POST results, and click Create. Results from linked agents will be POSTed to your URL with signature headers.

How Outbound Works

Outbound webhooks send agent results to an external URL when runs complete. You configure a destination URL, and Connic POSTs the results there. Best for sending results to external APIs, integrating with third-party services, and building event pipelines.

Note

Outbound-only webhooks cannot be triggered directly. They only send results when agents linked to them complete their runs.

Outbound Payload

What gets POSTed to your configured URL:

payload.json

{
  "run_id": "550e8400-e29b-41d4-a716-446655440000",
  "agent_name": "invoice-processor",
  "status": "completed",
  "output": "The invoice total is $1,234.56",
  "error": null,
  "started_at": "2024-01-15T10:30:00Z",
  "ended_at": "2024-01-15T10:30:05Z",
  "token_usage": {
    "prompt_tokens": 150,
    "candidates_tokens": 50,
    "total_tokens": 200
  }
}

Signature Verification

Every outbound webhook request includes HMAC-SHA256 signatures for security. Verify these signatures to ensure requests are authentic.

Request Headers

X-Connic-Signature - Hex-encoded HMAC-SHA256 signature
X-Connic-Timestamp - Unix timestamp (seconds) when the request was signed

How to Verify

Get the signing secret from your connector settings
Extract the timestamp and signature from headers
Concatenate timestamp + "." + raw request body
Compute HMAC-SHA256 of the concatenated string using your secret
Compare the computed signature with the received one
Optionally check timestamp is within 5 minutes to prevent replay attacks

Python Example

verify_webhook.py

import hmac
import hashlib
import time

def verify_webhook(payload: bytes, signature: str, timestamp: str, secret: str) -> bool:
    """Verify a Connic webhook signature."""
    # Check timestamp is not too old (5 minute window)
    if abs(time.time() - int(timestamp)) > 300:
        return False
    
    # Build the signed payload
    signed_payload = f"{timestamp}.".encode() + payload
    
    # Compute expected signature
    expected = hmac.new(
        secret.encode(),
        signed_payload,
        hashlib.sha256
    ).hexdigest()
    
    return hmac.compare_digest(expected, signature)

# Usage in Flask
@app.route("/webhook", methods=["POST"])
def handle_webhook():
    signature = request.headers.get("X-Connic-Signature", "")
    timestamp = request.headers.get("X-Connic-Timestamp", "")
    
    if not verify_webhook(request.data, signature, timestamp, SIGNING_SECRET):
        return "Invalid signature", 401
    
    # Process the webhook...
    return "OK", 200

Node.js Example

verify_webhook.js

import crypto from 'crypto';

function verifyWebhook(payload, signature, timestamp, secret) {
  // Check timestamp is not too old (5 minute window)
  const now = Math.floor(Date.now() / 1000);
  if (Math.abs(now - parseInt(timestamp)) > 300) {
    return false;
  }
  
  // Build the signed payload
  const signedPayload = `${timestamp}.${payload}`;
  
  // Compute expected signature
  const expected = crypto
    .createHmac('sha256', secret)
    .update(signedPayload)
    .digest('hex');
  
  return crypto.timingSafeEqual(
    Buffer.from(expected),
    Buffer.from(signature)
  );
}

// Usage in Express
app.post('/webhook', express.raw({ type: 'application/json' }), (req, res) => {
  const signature = req.headers['x-connic-signature'];
  const timestamp = req.headers['x-connic-timestamp'];
  
  if (!verifyWebhook(req.body.toString(), signature, timestamp, SIGNING_SECRET)) {
    return res.status(401).send('Invalid signature');
  }
  
  // Process the webhook...
  res.send('OK');
});

Security Best Practices

Always verify signatures in production
Use constant-time comparison to prevent timing attacks
Reject requests with timestamps older than 5 minutes
Store your signing secret securely (environment variables)

Sync Mode

Request-response pattern with immediate results. The webhook waits for agent completion and returns the result in the same response.

How Sync Works

Sync webhooks wait for the agent to complete and return the result in the same HTTP response. This provides a traditional request-response pattern. Best for REST API integrations, interactive applications, and short-running tasks.

Timeout

Default timeout is 5 minutes. For longer tasks, use Inbound mode and poll for results.

Setup Instructions

Create the connector

Open your agent, click Add inbound connector in the Connector Flow, then Create New Connector and select HTTP Webhook.

Select Sync (Request-Response) and copy credentials

Send requests

POST JSON to the webhook URL. The response blocks until the agent finishes and returns the result inline.

Response Format

response.json

{
  "status": "ok",
  "result": {
    "run_id": "550e8400-e29b-41d4-a716-446655440000",
    "agent_name": "invoice-processor",
    "status": "completed",
    "output": "The invoice total is $1,234.56",
    "error": null
  }
}

Client Examples

sync_request.py

import requests

url = "<webhook-url>"
secret = "<your-secret-key>"

payload = {"query": "What is the status of order 123?"}
resp = requests.post(
    url,
    json=payload,
    headers={"X-Connic-Secret": secret},
    timeout=60,
)
resp.raise_for_status()
print(resp.json()["result"]["output"])

sync_request.js

import fetch from "node-fetch";

const url = "<webhook-url>";
const secret = "<your-secret-key>";

const resp = await fetch(url, {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "X-Connic-Secret": secret,
  },
  body: JSON.stringify({ query: "Summarize the latest ticket" }),
});

if (!resp.ok) throw new Error(await resp.text());
const data = await resp.json();
console.log(data.result.output);
