Cards and expenses overview

The Cards API lets you issue cards on your Mamo account and turn every card transaction into an expense you can categorise, attach receipts to, and sync to your accounting software.

🚧
Available on request
Card issuing (partner cards and VCC cards) has to be enabled for your account. Contact [email protected] before you build against it.

Card types

Card	What it's for	Start with
Partner card	A virtual card with a spending limit, issued for a business partner	Create Partner Card
VCC card	A virtual card for one of your verified team members	Create VCC Card
Existing cards	The cards already issued on your account	Get Cards List

Once a card exists you can change its limit, cancel it, and list its transactions; the Cards section of the API Reference has every endpoint.

From transaction to expense

A card is used. You get a card_transaction.create webhook, and the transaction appears in Fetching Card Transactions.
Successful transactions become expenses. Find them with Search Expense Transactions.
Add the accounting details with Update Expense Transaction: category, tax rate, vendor and accounts. The values come from your connected accounting software, via the List Accounting endpoints.
Attach receipts with Upload Expense Receipts.

The Expense Object page describes the expense webhook payload field by field.
