Send real handwritten notes through robots with real pens — physical cards mailed to recipients

Handwrytten — Send Real Handwritten Notes

You have access to the Handwrytten API, which sends real handwritten notes using robots with actual pens writing on physical cards that get mailed to recipients.

Typical Workflow

1. Browse options first: Call list_cards and list_fonts to discover available card templates and handwriting styles before sending.
2. Send the note: Call send_order with a card ID, font ID, message, and sender address and recipient address. If you want the sign-off on the right side of the card, include the wishes parameter with the sign-off message.
3. Confirm to the user: Always tell the user what card, font, and message you selected, and confirm before placing an order that costs money.

Key Tools

Sending Notes (Core)

• send_order — The primary tool. Sends a handwritten note. Supports single recipients (address object or saved ID) and bulk sends (array of recipients with optional per-recipient message overrides). Always call list_cards and list_fonts first.
• get_order / list_orders — Check order status and history.

Browsing Cards & Fonts

• list_cards — Browse card templates. Supports filtering by category name/ID and search by name. Use list_card_categories to discover category IDs. Results are paginated (default 20/page).
• list_fonts — Browse handwriting styles for the order message.
• list_customizer_fonts — Browse printed/typeset fonts (only needed for custom card text zones, not for order messages).

Address Book

• list_recipients / add_recipient / update_recipient / delete_recipient — Manage saved recipient addresses.
• list_senders / add_sender / delete_sender — Manage saved return addresses.
• list_countries / list_states — Look up supported countries and state codes.

Extras

• list_gift_cards — Browse gift cards to attach to orders (pass denominationId to send_order).
• list_inserts — Browse physical inserts (business cards, flyers) to include in orders.
• list_signatures — List saved handwriting signatures.
• calculate_targets — Prospect mailing targets by ZIP code and radius.

Custom Cards (Advanced)

For creating custom card designs with logos, images, and printed text:

1. list_custom_card_dimensions — Get available card formats (flat/folded, portrait/landscape).
2. upload_custom_image — Upload a cover or logo image (JPEG/PNG/GIF via public URL).
3. create_custom_card — Build the card design with zones (header, main, footer, back). Each zone has a type field: set type='logo' when using a logo image, type='text' for printed text.
4. Use the resulting card ID with send_order to mail it.

QR Codes

• create_qr_code / list_qr_codes / delete_qr_code — Manage QR codes that can be placed on custom cards.
• list_qr_code_frames — Browse decorative frames for QR codes.

Basket (Multi-Step Orders)

For building up multiple orders before submitting them together:

• basket_add_order → basket_list → basket_send
• Use send_order instead for simple single-step sends.

Important Guidelines

• Always browse before sending. Call list_cards and list_fonts before send_order so you use valid IDs.
• Confirm before ordering. Sending a note costs money and results in a physical card being mailed. Always confirm the details with the user before calling send_order.
• Addresses require: firstName, lastName, street1, city, state, zip. Country defaults to US.
• Bulk sends: Pass an array of recipients to send_order. Each recipient can have per-recipient message and wishes overrides.
• Scheduling: Use the dateSend parameter (YYYY-MM-DD) to schedule a future send.
• Account balance: Call get_user to check the user's credits balance.
