Overview

To authenticate with Postscript, you need:
  1. Private API Key - A key that grants secure access to the Postscript API, enabling authorized applications to interact with Postscript resources and services.
This guide will walk you through finding your Private API Key in Postscript.

Prerequisites

  • An active Postscript account.

Instructions

Step 1: Finding your Private API Key

  1. Log in to Postscript, select your shop name in the side menu, then select API.
  2. If you don’t have a key yet, click Create Security Key Pair and confirm.
  3. Under the Private Key column, click Show and copy the value.
Use the Private Key (starts with sk_), not the Public Key (starts with pk_) — the Public Key doesn’t authenticate requests.

Step 2: Enter credentials in the Connect UI

Once you have your Private API Key:
  1. Open the form where you need to authenticate with Postscript.
  2. Enter your Private API Key in the field provided.
  3. Submit the form, and you should be successfully authenticated.
You are now connected to Postscript.
