# USPS

The **USPS Addresses API** validates address information to help improve delivery accuracy and reduce failed shipments.

**Setup**

1. Log in to the USPS developer portal at\
   <https://cop.usps.com/cop-navigator>\
   (You may need to create an account if you don’t already have one.)
2. Once logged in, select **My Apps** from the top-right toolbar.
3. Under **Getting Started**, follow the instructions to add a new app to your portal.
4. When prompted, add a name to your App - we suggest using "Formsort".
5. After the app is created, copy your **Consumer Key** and **Consumer Secret**.
6. Paste both values into the **USPS Addresses** integration settings in Formsort. Be sure to add a description, as this will help *you* identify your credentials in the Formsort UI.&#x20;
7. Make sure to deploy/redeploy your flows after integration setup.

Your USPS integration is now ready to validate addresses within your forms.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.formsort.com/integrations/integration-reference/usps.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
