This is the Handwrytten API for sending cards written in the handwriting of your choice. Using this API, you can send cards to anyone! You can also customize cards with logos, which can be saved and then used like any other card in the system. For a "sandbox" account, please set account to **test mode**. To move from credit card per-transaction to monthly invoicing, please contact us. ## Authentication Most api calls can include a `uid` in the `Authorization` header tag, or as a `uid` json parameter. To obtain a UID, you can either call **/auth/authorization** or use an API key from the app.handwrytten.com [integrations](https://app.handwrytten.com/api-keys) menu. Most people can take advantage of the Handwrytten API with just **one** API call - **orders/singleStepOrder**.
