# Quick Start

## :sparkles:Step by step

Follow these steps and you will have a working payment link in minutes:

{% stepper %}
{% step %}
\### Generate an API Key

Log in to the Partner Dashboard and go to **Team Preferences > API Keys**. Create a new key to identify your integration.

[<mark style="background-color:purple;">API Key</mark>](/getting-started/quick-start/api-keys.md)
{% endstep %}

{% step %}
\### Authenticate via OAuth 2.0

Use the API Key to obtain an access token using the **client credentials** grant type.

[<mark style="background-color:purple;">OAuth Authentication</mark>](https://github.com/getalternative/docs/blob/main/api/getting-started/quick-start/broken-reference/README.md)
{% endstep %}

{% step %}
\### **Create a payment request**

Use your access token to create a new payment request with the desired amount, currency, and redirect URL.

{% endstep %}

## 🧰 Environments & Base URLs

<table><thead><tr><th width="241">Environment</th><th>Base URL</th></tr></thead><tbody><tr><td>Production (default)</td><td><code>https://public-api.alternativepayments.io</code></td></tr><tr><td>Demo</td><td><code>https://public-api.demo.alternativepayments.io</code></td></tr></tbody></table>

All examples in this guide use production URLs. Switch to the demo when you test. Tokens and requests are isolated per environment.

{% hint style="danger" %}
\#### Caution

Tokens issued in one environment do **NOT** work in the other. Generate separate client credentials for demo and production.
{% endhint %}

{% hint style="warning" %}
\#### API Versioning

The current stable version is **v1**. Backward‑compatible changes (new fields, new statuses) are rolled out without a version bump. Breaking changes, if ever needed, will ship under `/v2`.
{% endhint %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.alternativepayments.io/getting-started/quick-start.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.
