# Accept Payments Online
Integrate GoBTC Pay into a website or web app with the **Web SDK**. The integration authenticates with a terminal's **Terminal key (Web SDK)**.
{% hint style="info" %}
**Before you begin.** Payments cannot be settled until you have a [linked receiving wallet](/guides/account-settings.md#receiving-wallet-and-custody).
{% endhint %}
### Step 1: Create a store and terminal
1. Open **Stores** and click **Add store:**
2. Enter a **Store name** (address and country are optional), then click **Create store**.
3. On the store's row, click **Manage:**
4. On the **Terminals** tab, click **Add terminal:**\
5. Enter a **Terminal name** (location is optional), then click **Add terminal**.
6. Pair the terminal with the GoBTC Pay POS app.
See [Stores and POS Terminals](/stores-and-pos-terminals.md).
### Step 2: Get the Terminal key (Web SDK)
Open the terminal to see its details, including the **Terminal key (Web SDK):**
This key authenticates your web integration for that terminal.
{% hint style="warning" %}
Keep the Terminal key server-side. If it may have been exposed, use the **Rotate key** to invalidate the old one.
{% endhint %}
### Step 3: Build your checkout
Use the **Terminal key** with the Web SDK to present checkout on your site. When the customer pays from the GoBTC Pay app and approves, you get an instant **Approved** response; on-chain settlement follows in a later batch (see [Payment Lifecycle](/guides/payment-lifecycle.md)).

`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.
