# Sandbox

> Use the X Ads API sandbox environment to safely test campaign workflows, create test advertiser accounts, and manage funding instruments without serving ads.

The sandbox is an environment for you to test and build your Ads API implementation.

Campaigns created via the sandbox will not be served to users and test records for objects such as Funding Instruments can be created dynamically.

Using the sandbox is as simple as calling the appropriate hostname of ads-api-sandbox.x.com but it also contains some unique functionality found only in the sandbox.

Make an initial request to [POST accounts](/x-ads-api/campaign-management/reference#post-accounts) to create a new advertiser account. The response from this call will contain an account\_id that can be used for subsequent requests. These endpoints enable consumers to create and test against multiple advertiser accounts.

* [POST accounts](/x-ads-api/campaign-management/reference#post-accounts) Create an account on the sandbox
