--- name: constant-contact description: | Constant Contact API integration with managed OAuth. This is a write-capable integration — it can read, create, update, delete, and bulk-modify contacts, email campaigns, contact lists, tags, custom fields, segments, and marketing analytics. Use this skill when users want to interact with Constant Contact marketing data. All write operations (POST, PUT, DELETE, bulk actions, campaign sending/scheduling) require explicit user approval with specific resource identifiers before execution. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key. metadata: author: maton version: "1.0" clawdbot: emoji: 🧠 requires: env: - MATON_API_KEY --- # Constant Contact Access the Constant Contact V3 API with managed OAuth authentication. Manage contacts, email campaigns, contact lists, tags, custom fields, segments, bulk operations, and marketing analytics. ## Quick Start ```bash # List contacts python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.maton.ai/constant-contact/v3/contacts') 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://api.maton.ai/constant-contact/v3/{resource} ``` Maton proxies requests to `api.cc.email/v3` 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`: ```bash 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 Constant Contact OAuth connections at `https://api.maton.ai`. ### List Connections ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.maton.ai/connections?app=constant-contact&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 ```bash python <<'EOF' import urllib.request, os, json data = json.dumps({'app': 'constant-contact'}).encode() req = urllib.request.Request('https://api.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 ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.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:** ```json { "connection": { "connection_id": "{connection_id}", "status": "ACTIVE", "creation_time": "2026-02-07T07:41:05.859244Z", "last_updated_time": "2026-02-07T07:41:32.658230Z", "url": "https://connect.maton.ai/?session_token=...", "app": "constant-contact", "metadata": {} } } ``` Open the returned `url` in a browser to complete OAuth authorization. ### Delete Connection ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.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 Constant Contact connections, specify which one to use with the `Maton-Connection` header: ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.maton.ai/constant-contact/v3/contacts') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Maton-Connection', '{connection_id}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ``` Always include the `Maton-Connection` header to ensure requests go to the intended account, especially before any write operation. If you have multiple connections and omit this header, the gateway uses the default connection, which may not be the intended account. ## Security & Permissions - Access is scoped to contacts, email campaigns, lists, segments, tags, custom fields, and marketing analytics within the connected Constant Contact account. Only install if you need Constant Contact administration. Revoke unused connections promptly. - **Default to read-only operations.** Always start by listing or retrieving resources to confirm identifiers before proposing any changes. - **All write operations require explicit user approval with specific identifiers.** Before executing any POST, PUT, PATCH, or DELETE call: 1. Retrieve and display the target resource (contact email, list name, campaign name/ID) so the user can verify. 2. Clearly describe the intended effect (e.g., "This will delete contact 'john@example.com' (ID: abc123) from your account"). 3. Wait for explicit user confirmation before proceeding. - **High-impact operations require extra caution.** Sending/scheduling email campaigns, bulk contact deletions, bulk list membership changes, and importing contacts can affect large numbers of marketing contacts and external recipients. These actions must include a summary of consequences and require confirmation. - **Campaign sending is irreversible** — emails are delivered to external recipients immediately. Always preview the campaign and confirm recipients, subject, and content before sending or scheduling. ## API Reference ### Account #### Get Account Summary ```bash GET /constant-contact/v3/account/summary ``` **Response:** ```json { "contact_email": "user@example.com", "contact_phone": "5551234567", "country_code": "us", "encoded_account_id": "abc123", "first_name": "John", "last_name": "Doe", "organization_name": "Acme Inc", "state_code": "CA", "time_zone_id": "US/Eastern" } ``` #### Update Account Summary ```bash PUT /constant-contact/v3/account/summary Content-Type: application/json { "first_name": "John", "last_name": "Doe", "organization_name": "Acme Inc", "time_zone_id": "US/Eastern" } ``` #### Get Account Emails Returns confirmed sender email addresses for the account. ```bash GET /constant-contact/v3/account/emails ``` **Response:** ```json [ { "email_id": 1, "email_address": "marketing@example.com", "roles": ["BILLING", "CONTACT", "DEFAULT_FROM", "REPLY_TO"], "confirm_status": "CONFIRMED", "confirm_time": "2026-02-05T07:32:49.766+0000", "confirm_source_type": "SITE_OWNER" } ] ``` #### Add Account Email ```bash POST /constant-contact/v3/account/emails Content-Type: application/json { "email_address": "newsender@example.com" } ``` A confirmation email will be sent to the address.

Draft campaigns return 404. #### Contact Activity Summary ```bash GET /constant-contact/v3/reports/contact_reports/{contact_id}/activity_summary ``` **Response:** ```json { "contact_id": "uuid", "campaign_activities": [ { "campaign_activity_id": "uuid", "sends": 1, "opens": 1, "clicks": 0, "bounces": 0 } ] } ``` ## Pagination The API uses cursor-based pagination with a `limit` parameter: ```bash GET /constant-contact/v3/contacts?limit=50 ``` Response includes pagination links: ```json { "contacts": [...], "_links": { "next": { "href": "/v3/contacts?cursor=abc123" } } } ``` Use the cursor from the `next` link for subsequent pages: ```bash GET /constant-contact/v3/contacts?cursor=abc123 ``` When there are no more pages, the `_links.next` field is absent from the response. ## Code Examples ### JavaScript ```javascript const response = await fetch( 'https://api.maton.ai/constant-contact/v3/contacts?limit=50', { headers: { 'Authorization': `Bearer ${process.env.MATON_API_KEY}` } } ); const data = await response.json(); ``` ### Python ```python import os import requests response = requests.get( 'https://api.maton.ai/constant-contact/v3/contacts', headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}, params={'limit': 50} ) data = response.json() ``` ## Notes - Resource IDs use UUID format (36 characters with hyphens) - All dates use ISO-8601 format: `YYYY-MM-DDThh:mm:ss.sZ` - Maximum 1,000 contact lists per account - A contact can belong to up to 50 lists - Bulk operations are asynchronous - check activity status for completion - Email campaigns require confirmed sender email addresses - `format_type: 5` for custom HTML emails - `create_source` is required when creating contacts; `update_source` is required when updating - Scheduling a campaign requires a valid physical address on the account and at least one target list - Delete operations on tags and lists return `202 Accepted` (asynchronous); contacts and campaigns return `204 No Content` - IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets to disable glob parsing - IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments ## Error Handling | Status | Meaning | |--------|---------| | 400 | Missing Constant Contact connection or invalid request | | 401 | Invalid or missing Maton API key, or OAuth token expired | | 403 | Insufficient permissions for the requested operation | | 404 | Resource not found | | 409 | Conflict (e.g., duplicate email address) | | 429 | Rate limited | | 4xx/5xx | Passthrough error from Constant Contact API | ### Error Response Format ```json [ { "error_key": "contacts.api.validation.error", "error_message": "create_source is missing, create_source does not have a valid value" } ] ``` ### Troubleshooting: API Key Issues 1. Check that the `MATON_API_KEY` environment variable is set: ```bash echo $MATON_API_KEY ``` 2. Verify the API key is valid by listing connections: ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.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 `constant-contact`. For example: - Correct: `https://api.maton.ai/constant-contact/v3/contacts` - Incorrect: `https://api.maton.ai/v3/contacts` ## Resources - [Constant Contact V3 API Overview](https://developer.constantcontact.com/api_guide/getting_started.html) - [API Reference](https://developer.constantcontact.com/api_reference/index.html) - [Technical Overview](https://developer.constantcontact.com/api_guide/v3_technical_overview.html) - [Contacts Overview](https://developer.constantcontact.com/api_guide/contacts_overview.html) - [Email Campaigns Guide](https://developer.constantcontact.com/api_guide/email_campaigns_get_started.html) - [Contact Lists Overview](https://v3.developer.constantcontact.com/api_guide/lists_overview.html) - [Maton Community](https://discord.com/invite/dBfFAcefs2) - [Maton Support](mailto:support@maton.ai)
