Once registered, you will automatically receive an email containing your assigned Web Tools User ID. After you receive this email, you can use the following APIs:

• Price Calculators
• Service Standards & Commitments
• Address Information
• Package Pickup

The API containing "Certify" is our testing API and will print labels with the sample watermark. In order to generate actual labels, you must remove "Certify" from all of your Web Tools XML requests.

We currently only offer Every Door Direct Mail^® (EDDM^®) services through our online application.

To provide the very best API offering, we periodically update our systems which may require current customers to update their software. To determine if these changes/updates apply to you, refer to our most recent Release Notes. This document contains all new changes and steps to resolve if you are affected. Please remember to first contact your software provider for any integration-related questions.

The login page on USPS.com^® is not related to APIs. There is no "log in" functionality for your Web Tools credentials. Your username and password will allow you to gain access to the Web Tools servers.

Use your credentials to:

• Log into the interface of your third-party software
• Add authentication to your back-end programming in the API, XML

The login page shown on the usps.com website is not associated to APIs. Please review the technical documentation if you need more information about integration.

The production URLs included in the email confirming your registration with Web Tools are not links to a viewable website. These URLs must be included in the XML Request used to connect to our APIs (please refer to our technical documentation) for more information. If you are using a third party ecommerce software, it's possible that these URLs are not required, and therefore, do not apply to all customers using our APIs. Please contact your software provider for more specific details concerning integration requirements.

Since USPS^® does not know every specific integration requirements of all the possible software options available, we recommend that customers first contact their provider to troubleshoot integration-specific questions.

We will be happy to assist all customers provided the following information is included when you contact the Internet Customer Care Center.

Customers must provide:

• Copy of a sample XML request resulting in the issue or error, pasted into the body of the email
• Complete description of exact issue you are experiencing
• Name of API
• Name of third party software provider

Please note that without the above information, our USPS^® agents will not have sufficient information to investigate Web Tools API issues properly.

If you have technical questions or need more information, contact the Internet Customer Care Center (ICCC).
