# Get sandbox credentials

 <div class="amber-callout" aria-label="Migration notice"><p><strong>Migrate to Global APIs:</strong> New sellers and approved Solution Providers should use Global APIs.

Get sandbox credentials as a seller or solution provider.

* Sellers are businesses that list and sell products on Walmart's platform.
* Solution providers are third-party companies that provide specialized services to help run a seller's eCommerce business.

### Get sandbox credentials as a seller

As a seller, to get sandbox credentials:

1. Log into the Walmart Developer Portal with your Seller Center credentials.
2. Select **API Keys**.
3. Select the **Sandbox Keys** tab.
4. Complete the prompts to create your sandbox client ID and client secret.
5. Call the Token API with a Base64 (utf-8, Unix newline separators) encoding of your client ID and client Secret to generate an access token.

**Step result:** You can now use your access token to start testing your API integrations in the sandbox.

### Get sandbox credentials as a solution provider

Solution providers can use delegated access to use the sandbox. Walmart Marketplace sellers delegate access to their accounts by providing sandbox keys to their solution provider.

As a seller, complete the steps to provide delegated sandbox access to a Solution Provider.

1. Log into the Walmart Developer Portal.
2. Select **My Account**.
3. Enter your username and password. The API Keys page displays.
4. Select the **SANDBOX KEYS** tab.
5. Select **Add New Key for a Solution Provider**.
6. From the dropdown menu, select the provider name.
7. Select your access permissions.
8. Select **Save**.
9. Share your client ID and client secret with your solution provider.
