SignNow API integration with managed OAuth. E-signature platform for sending, signing, and managing documents.

Use this skill when users want to upload documents, send signature invites, create templates, or manage e-signature workflows.

For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

Requires network access and valid Maton API key.

# SignNow

Access the SignNow API with managed OAuth authentication. Upload documents, send signature invites, manage templates, and automate e-signature workflows.

Quick Start

# Get current user info
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/signnow/user')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://gateway.maton.ai/signnow/{resource}

The gateway proxies requests to `api.signnow.com` and automatically injects your OAuth token.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

**Environment Variable:** Set your API key as `MATON_API_KEY`:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)

2. Go to [maton.ai/settings](https://maton.ai/settings)

3. Copy your API key

Connection Management

Manage your SignNow OAuth connections at `https://ctrl.maton.ai`.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=signnow&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Create Connection

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'signnow'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Get Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

**Response:**

{
  "connection": {
    "connection_id": "5ff5474b-5f21-41ba-8bf3-afb33cce5a75",
    "status": "ACTIVE",
    "creation_time": "2026-02-08T20:47:23.019763Z",
    "last_updated_time": "2026-02-08T20:50:32.210896Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "signnow",
    "metadata": {}
  }
}

Open the returned `url` in a browser to complete OAuth authorization.

Delete Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple SignNow connections, specify which one to use with the `Maton-Connection` header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/signnow/user')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '5ff5474b-5f21-41ba-8bf3-afb33cce5a75')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

Code Examples

JavaScript

const response = await fetch(
  'https://gateway.maton.ai/signnow/user',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://gateway.maton.ai/signnow/user',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()

Python (Upload Document)

import os
import requests

with open('document.pdf', 'rb') as f:
    response = requests.post(
        'https://gateway.maton.ai/signnow/document',
        headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
        files={'file': ('document.pdf', f, 'application/pdf')}
    )
doc = response.json()
print(f"Uploaded document: {doc['id']}")

Python (Send Invite)

import os
import requests

doc_id = "c63a7bc73f03449c987bf0feaa36e96212408352"
response = requests.post(
    f'https://gateway.maton.ai/signnow/document/{doc_id}/invite',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'to': 'signer@example.com',
        'from': 'sender@example.com'
    }
)
result = response.json()
print(f"Invite sent: {result['id']}")

Notes

Documents must be in PDF format for upload

Supported file types: PDF, DOC, DOCX, ODT, RTF, PNG, JPG

System folders (Documents, Templates, Archive, Trash Bin) cannot be renamed or deleted

Creating signing links requires documents to have signature fields

Custom invite subject/message requires a paid subscription

Rate limit in development mode: 500 requests/hour per application

IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments

Error Handling

| Status | Meaning |

|--------|---------|

| 400 | Missing SignNow connection or bad request |

| 401 | Invalid or missing Maton API key |

| 403 | Insufficient permissions or subscription required |

| 404 | Resource not found |

| 405 | Method not allowed |

| 429 | Rate limited |

| 4xx/5xx | Passthrough error from SignNow API |

SignNow errors include detailed messages:

{
  "errors": [
    {
      "code": 65578,
      "message": "Invalid file type."
    }
  ]
}

Troubleshooting: API Key Issues

1. Check that the `MATON_API_KEY` environment variable is set:

echo $MATON_API_KEY

2. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `signnow`. For example:

Correct: `https://gateway.maton.ai/signnow/user`

Incorrect: `https://gateway.maton.ai/user`
