Prerequisites
To integrate Checkout API, it is important to meet the requirements shown below.
| Requirement | Description |
| Application | Applications are the different integrations in one or more stores. You can create an application for each solution you implement to keep everything organized and on track for easier management. Check Your integrations for more information on how to create an application. |
| Credentials | Credentials are unique keys that we provide for you to configure your integrations. You will need a pair of test credentials to test the integration and a pair of production credentials to receive actual payments. See Credentials for more information. |
| MercadoPago.js | MercadoPago.js allows you to manage card data to comply with the necessary security requirements and avoid sending sensitive data to its servers. For this, our library generates a token that represents this information and allows you to operate safely. See SDKs to access MercadoPago.js. |
If all the prerequisites have been met, you can perform the Checkout API integration.
