How to find PayPal API Credentials username, password, and signature: A Step-by-Step Guide

Discovering your PayPal API username, password, and signature information is crucial for many apps to integrate. However, navigating through the PayPal admin interface to locate these details can be challenging. Here’s a comprehensive guide on how to obtain them effortlessly.

But first, why are these API credentials essential?

PayPal allows seamless communication between various applications, shopping carts, reporting systems, and websites through what is known as an API. This API performs various functions, such as checking your PayPal balance, retrieving transaction details, issuing refunds, and more.

To safeguard your PayPal account, API access must be restricted to those with proper authentication. The correct combination of API username, password, and signature is imperative to securely access your PayPal account information from third-party apps or websites.

Here’s a step-by-step process to acquire your API details:

Option 1: Under Tools, More Tools (for the latest PayPal interface)

  1. Log in to your PayPal account.
  2. Hover over the Tools menu in the top navigation and find More Tools. Click it.
  3. Scroll until you find a box with API credentials. Click on it.

4. Shortcut, to directly open the Tools page in your PayPal account.
5. On the API credentials page, select the last option for NVP/SOAP API integration.


6. If it’s your first time creating API credentials, complete the API Credential Request form.
7. Once created, locate the View API Signature option under NVP/SOAP API integration. Clicking on it will reveal your API username, password, and signature.
