clawemailGoogle Workspace via ClawEmail.com service — Gmail, Drive, Docs, Sheets, Slides, Calendar, Forms. Use PROACTIVELY when the user asks to send email, create documents, manage files, schedule events, or work with any Google service.

Claw — Google Workspace for AI Agents

Use claw for Gmail, Drive, Docs, Sheets, Slides, Calendar, and Forms via your @clawemail.com account.

Setup

  1. Save your ClawEmail credentials JSON to ~/.config/clawemail/credentials.json
  2. Set the environment variable: export CLAWEMAIL_CREDENTIALS=~/.config/clawemail/credentials.json

Get credentials at https://clawemail.com — sign up, then visit /connect/YOUR_PREFIX to authorize OAuth.

Getting an Access Token

All API calls need a Bearer token. Use the helper script to refresh and cache it:

TOKEN=$(~/.openclaw/skills/clawemail/scripts/token.sh)

The script caches tokens for 50 minutes. Always assign to TOKEN before making API calls.

Gmail

Search emails

TOKEN=$(~/.openclaw/skills/clawemail/scripts/token.sh)
curl -s -H "Authorization: Bearer $TOKEN" \
  "https://gmail.googleapis.com/gmail/v1/users/me/messages?q=newer_than:7d&maxResults=10" | python3 -m json.tool

Common query operators: from:, to:, subject:, newer_than:, older_than:, is:unread, has:attachment, label:, in:inbox.

Read a message

curl -s -H "Authorization: Bearer $TOKEN" \
  "https://gmail.googleapis.com/gmail/v1/users/me/messages/MESSAGE_ID?format=full" | python3 -m json.tool

For plain text body only, use format=minimal and decode the payload. For readable output:

curl -s -H "Authorization: Bearer $TOKEN" \
  "https://gmail.googleapis.com/gmail/v1/users/me/messages/MESSAGE_ID?format=full" \
  | python3 -c "
import json,sys,base64
m=json.load(sys.stdin)
hdrs={h['name']:h['value'] for h in m['payload']['headers']}
print(f\"From: {hdrs.get('From','')}\nTo: {hdrs.get('To','')}\nSubject: {hdrs.get('Subject','')}\nDate: {hdrs.get('Date','')}\n\")
def get_body(part):
    if part.get('body',{}).get('data'):
        return base64.urlsafe_b64decode(part['body']['data']).decode('utf-8','replace')
    for p in part.get('parts',[]):
        if p['mimeType']=='text/plain': return get_body(p)
    for p in part.get('parts',[]):
        b=get_body(p)
        if b: return b
    return ''
print(get_body(m['payload']))
"

Send an email

Tips

  • Always refresh token first: Start every sequence with TOKEN=$(~/.openclaw/skills/clawemail/scripts/token.sh)
  • JSON output: Pipe through python3 -m json.tool for readable output, or | python3 -c "import json,sys;..." for extraction
  • Pagination: Most list endpoints return nextPageToken. Pass it as ?pageToken=TOKEN for the next page
  • Batch operations: Docs, Sheets, and Slides support batchUpdate — send multiple operations in one request
  • Error 401: Token expired. Re-run token.sh to refresh
  • Error 403: Scope not authorized. The ClawEmail OAuth includes Gmail, Drive, Docs, Sheets, Slides, Calendar, and Forms scopes
  • Rate limits: Google APIs have per-user rate limits. Add brief delays between rapid successive calls
  • File IDs: Google Docs/Sheets/Slides URLs contain the file ID: https://docs.google.com/document/d/FILE_ID/edit

When to Use

  • User asks to send, read, or search email
  • User wants to create or edit documents, spreadsheets, or presentations
  • User needs to manage files in Google Drive
  • User wants to schedule or check calendar events
  • User asks to create forms or review form responses
  • Any task involving Google Workspace services
