Omnisend + ChatGPT
Manage Omnisend (e-commerce marketing automation: contacts, campaigns, events, products, categories) from any AI agent. 9 tools, X-API-KEY auth.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
OMNISEND_API_KEY
Step 1 — Get credentials
This connector wraps the Omnisend REST API v3 (api.omnisend.com/v3).
Setup:
- Log into https://app.omnisend.com → top-right avatar → Store settings → Integrations & API → API keys → Create API key.
- Set
OMNISEND_API_KEY.
Authentication: X-API-KEY: ${OMNISEND_API_KEY}.
Contact statuses: subscribed, unsubscribed, nonSubscribed — per channel (email vs SMS).
Custom events: trigger automations via the events endpoint. Send an event with name + email/contactID + properties; Omnisend matches it to active workflows.
Pagination: cursor-based via paging.next. limit (max 250).
Rate limits: 400 req/min per token. 429 with Retry-After.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
git clone https://github.com/HelpCode-ai/anythingmcp.git

- Name:
Omnisend - MCP server URL:
https://cloud.anythingmcp.com/mcp - Authentication: Bearer token → paste your MCP API key (from AnythingMCP → Profile → MCP API Keys → New Key)
