## Postman collection

A Postman collection is available to get started quickly with the **eSAW One-Shot** API. It includes requests for:

1. **Create certificate request** — `POST /api/v1/esawoneshot` (Uanataca host, client certificate)
2. **Upload file** — `POST /Api/v6/file/upload` (eSAW host, ApiToken)
3. **Send envelope** — `POST /Api/v6/envelope/send` (eSAW host, ApiToken)


You can use it to validate the full flow without writing custom code.

## Setup

1. Download the **eSAW One-Shot Postman collection** (from the Uanataca developer portal or by request to Uanataca).
2. Import the collection into Postman.
3. Configure the **host** variable in the Postman environment with the desired domain(s).


Because eSAW One-Shot uses two hosts (Uanataca and eSignAnywhere), you may need to set:

- **Uanataca host** — e.g. `https://api.sandbox.modernpki.com` (for create request)
- **eSAW host** — e.g. `https://demo.esignanywhere.net` (for file upload and envelope send)


If the collection uses a single `host` variable, set it according to the request (or duplicate requests and point each to the correct base URL).

1. For Uanataca requests, configure Postman to use **Client certificate** (certificate and key) for SSL.
2. For eSAW requests, set the **ApiToken** header to your eSignAnywhere API token.


## Sandbox environment

When testing against sandbox:

- **Uanataca:** `https://api.sandbox.modernpki.com`
- **eSAW:** `https://demo.esignanywhere.net`


Use the client certificate provided for sandbox and the API token from your eSAW demo account.
