Pagination in API responses is a technique used to manage and navigate large sets of data by dividing them into manageable chunks, or pages. This improves performance and usability by allowing clients to request smaller, more digestible pieces of data.

Common Pagination Techniques:

1. Offset-Based Pagination:
   • Method: Use offset and limit parameters.
   • Example: GET /items?offset=20&limit=10
   • Pros: Simple to implement and understand.
   • Cons: Can be inefficient with large datasets as it skips over records.
2. Cursor-Based Pagination:
   • Method: Use a cursor to keep track of the position.
   • Example: GET /items?cursor=abc123&limit=10
   • Pros: More efficient with large datasets; avoids skipping records.
   • Cons: More complex to implement; requires unique, sequential identifiers.
3. Page-Based Pagination:
   • Method: Use page number and size parameters.
   • Example: GET /items?page=2&size=10
   • Pros: Simple and intuitive for users.
   • Cons: Similar inefficiency issues as offset-based pagination with large datasets.

Each technique has its use case, with cursor-based pagination generally preferred for its efficiency with large datasets, while offset-based and page-based are simpler and easier for smaller datasets.
