Integrations Overview
What it is
thanks.io connects to the tools you already use through native integrations, automation platforms, e-commerce platforms, AI assistants, and a REST API with webhooks.
Every integration is listed on the Integrations & API page: click Integrations & API in the dashboard sidebar (under Send). Each card links to the app's listing or setup guide.
Sending a creative from an integration
Integrations send the designs you build in Creatives. A creative is a front and a message saved together, and each one has an ID you can copy from its menu (Copy creative ID). Where an integration lets you pick a creative, it sends the piece exactly as saved:
| Integration | How you choose the design |
|---|---|
| HubSpot | Record tab: Your creatives tiles, or pick a design. Workflow actions: the Creative dropdown, or the template fields |
| n8n | The Creative field on every send action (pick from a list or enter the ID), or the template fields |
| Zapier and Make | Image and message template fields; a creative ID where your action step exposes it |
| AI assistants | Ask for a creative by name; the assistant lists your creatives and sends by creative ID |
| REST API | creative_id on every send and estimate endpoint, or the template fields |
Only creatives that are ready to send (they have a message, and a front unless they are letters) can be sent from an integration. See Finding template IDs for where each ID appears.

AI assistants
Connect Claude, ChatGPT, Cursor, VS Code, or any assistant that supports MCP (the open standard AI assistants use to work with other apps) to your thanks.io account. Once connected, you can ask it in plain language to check your balance and results, build mailing lists, design and list creatives, send postcards, letters, notecards and gift cards, and track your orders.
- Click Integrations & API in the sidebar.
- On the AI Assistants card, click Connect Your AI.
- Either copy the setup prompt and paste it into your assistant, which walks you through connecting, or follow the steps on your assistant's tab (Claude, ChatGPT, Claude Code, Cursor, VS Code, or Other) using the server URL
https://mcp.thanks.io/mcp. - Sign in to thanks.io when asked and approve access. Most assistants need no API key. For one that can't sign in, create a key under Settings → API Access with Allow MCP access turned on and use it as the bearer token.
An AI assistant can send real mail, which charges your balance or card and can't be undone once printing starts. thanks.io tells the assistant to show you a preview and wait for your go-ahead before every send, so read the preview before you approve.
REST API + Webhooks
Build fully custom integrations using the REST API v2. See API Overview.
Tips & best practices
- Start with a native integration or automation platform before building a custom API integration.
- Turn on Test Mode (Settings → API Access) to test sends placed through the API or Zapier without printing or shipping real mail.
- Build and preview the design in Creatives before you wire it into an integration, then pick or paste that creative.
- When connecting via Zapier or Make, test with a single recipient before enabling large automations.
