• API (Application Programming Interface): A set of rules and specifications that allows different software applications to communicate and exchange data with each other.
• SFTP (Secure File Transfer Protocol): A secure method of transferring files between computers over a network, often used for batch data uploads.
• REST API (Representational State Transfer Application Programming Interface): An architectural style for designing networked applications that relies on stateless communication using standard HTTP methods.
• JSON (JavaScript Object Notation): A lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.
• Schema: A formal description of the structure and data types of a file or data structure, ensuring consistency and proper interpretation of the data.
• Endpoint: A specific URL that represents a resource in a REST API, allowing applications to access or manipulate that resource using HTTP methods.
• Payload: The actual data being transmitted in a request or response in an API call.
  Merchant Ingestion: The process of transferring merchant-related data from a Demand Partner to the CDLX system.
• Offer Ingestion: The process of transferring offer-related data from a Demand Partner to the CDLX system.
  Redemption Feed: A data stream provided by CDLX to Demand Partners containing information about transaction redemptions related to their offers.

• Base64 Encoding: A method of converting binary data into an ASCII string format, often used to embed images or other binary files within text-based data formats like JSON.
• RPS (Requests Per Second): The number of API calls a client can make to a server within one second, often used to manage API usage and prevent overload.
