For Partners

Create orders. Send invoices. Get paid.

Our Partner API lets you generate invoices for personalized apparel and leather on behalf of your customers. POST an order, get back a hosted pay link on monogram.shop — your customer pays through our secure checkout, and we handle production and shipping end-to-end. You set the amount, you set the customization — the invoice mirrors what you're billing.

1 · Authenticate

Send your API key in the Authorization header.

2 · POST an order

Pass items, customer details, your reference, and (optionally) your own amount.

3 · Share the link

We return a hosted payment page on our site.

Endpoints

All four endpoints at a glance

Every endpoint takes the same Bearer authentication. Anchor links jump to the section with full request/response details.

Method	Path	What it does	Details
POST	/api/v1/partner/orders	Create an invoice. Returns a hosted pay link.	jump ↓
GET	/api/v1/partner/orders	List your invoices. Filter by status or reference, paginate with cursor.	jump ↓
GET	/api/v1/partner/orders/{id}	Fetch one invoice in full — items, personalization, breakdown.	jump ↓
GET	/api/products	Live product catalog. Same data as the section below.	jump ↓

Common gotcha: the path is /orders (plural), not /order.

Anatomy of a request

What the fields mean

Every order body has the same five concepts. Get these right and the rest follows — examples below.

productSlug

A short, URL-safe identifier for a product family. Lowercase, hyphenated, stable forever.

monogram-tee

Pick from the catalog below.

variantSku

The specific size/colour/material option within a product. Globally unique.

tee-blk-m

Must belong to the productSlug you've chosen.

personalization

Customization keys vary per product (monogram, thread, placement…).

{ "monogram": "J.D.", "thread": "Gold" }

Required fields are marked on each product card.

amountCents

Optional. Your own unit price in integer cents — overrides catalog price.

7500  // $75.00

Up to $100,000 per line item. Omit to use the catalog price.

reference

Optional. Your invoice ID. We store and echo it back on the order and webhooks.

INV-2026-00891

Max 120 chars. Useful for reconciliation.

quantity

How many of this variant. Integer between 1 and 50 per line item.

Subtotal = (amountCents or catalog price) × quantity.

Partner-set pricing

Add an amountCents field to any line item to bill at the price you've quoted, instead of the catalog price. The hosted pay link will charge that exact total — ideal for wholesale, bespoke runs, gift orders, or contracted rates.

· amountCents is the unit price in cents — subtotal = amountCents × quantity.
· Up to $100,000 per line item. Omit to fall back to the catalog price shown below.
· Personalization length limits are relaxed on partner orders — submit the monogram, message or engraving as quoted.
· Required personalization fields are still enforced — partners must send all keys marked required.

Catalog

Every product, every variant

Use the productSlug and variantSku values below in your order body. Personalization keys differ per product — each card lists exactly what to send.

Pagination tip

On every list response, if nextCursor is non-null, pass it back as ?cursor=<value> to get the next page. When nextCursor comes back as null, you've reached the end.

If something fails
