API to add or delete the merchants into the DS Platform. All request and response payloads are sent in the JSON (JavaScript Object Notation) data-interchange format. Each endpoint in the API specifies the HTTP Method used to access it. <br> __Authentication__ <br>Mastercard uses OAuth 1.0a with body hash extension for authenticating the API clients. <br>This requires every request that you send to Mastercard to be signed with an RSA private key. <br> A private-public RSA key pair must be generated consisting of <br> 1. A private key for the OAuth signature for API requests. It is recommended to keep the private key in a password-protected or hardware keystore.<br> 2. A public key is shared with Mastercard during the project setup process through either a certificate signing request (CSR) or the API Key Generator. Mastercard will use the public key to verify the OAuth signature that is provided on every API call.<br> An OAUTH1.0a signer library is available on [GitHub](https://github.com/Mastercard/oauth1-signer-java)<br> __The Merchant Enrollment API is provided in two environments__ <br>1.
