What is pagination in Apis?

In today’s world, almost every software application is built using APIs. APIs or Application Programming Interfaces are interfaces between different software systems that enable them to interact with each other. APIs allow software applications to share data, functionality, and services with each other.

One of the most important features of APIs is pagination. Pagination is a process that’s used to divide a large dataset into smaller chunks (pages). All Square API endpoints that return a list of resources support pagination. In this post, we will explain what pagination is and why it’s important in APIs.

What is Pagination?

Pagination is a process of dividing large datasets into smaller parts or pages. When retrieving data from an API, pagination is used to limit the number of results returned in a single response, making it easier to handle large amounts of data.

For example, consider an e-commerce website that has thousands of products listed on its website. When a user searches for a particular product, the website will fetch all of the matching products and display them on a single page. This can slow down the website and make it difficult for users to find what they are looking for.

To solve this problem, the website can use pagination to divide the search results into multiple pages. This way, the user can view a limited number of search results per page, making it easier to navigate through the results.

Why is Pagination Important in APIs?

Pagination is important in APIs for three main reasons:

1. Efficiency

When data is retrieved from APIs, it can often be a large dataset. By using pagination, APIs can divide this dataset into smaller parts, allowing for faster and more efficient data retrieval for users. Pagination can also improve the performance of APIs, making them faster and more reliable.

2. Flexibility

Pagination allows developers to retrieve a specific set of data by specifying the page number and the number of results per page. This allows developers to retrieve data based on their specific requirements, making the API more flexible.

3. User Experience

Pagination improves the user experience of an application by making it easier to navigate through large datasets. By dividing the data into smaller pages, users can view a limited number of results at a time, making it easier to find what they are looking for. Pagination also reduces the need for users to scroll through large lists of data, which can be time-consuming and frustrating.

How Pagination Works in APIs?

Pagination works by using two parameters: limit and offset. The limit parameter specifies the maximum number of results to be returned in a single response, while the offset parameter specifies the starting point for the results.

For example, consider an API endpoint that returns a list of customers. The API might have thousands of customers, but we only want to retrieve 10 customers per page. To retrieve the first 10 customers, we would set the limit to 10 and the offset to 0. To retrieve the next 10 customers, we would set the limit to 10 and the offset to 10.

Here’s an example request that retrieves 10 customers starting from the 20th customer:

GET /customers?limit=10&offset=20 HTTP/1.1

In this example, the API will return the 20th to 30th customers.

Pagination Best Practices

When using pagination in APIs, there are several best practices that developers should follow:

1. Use Consistent Pagination Parameters

Developers should use consistent pagination parameters when building APIs. This means that the parameters should have the same name and format across all endpoints. This makes it easier for developers to use and integrate with the API.

2. Return Total Result Count

APIs should return the total number of results available in the dataset. This allows developers to retrieve all the data if needed, and informs them if there are more pages beyond the current page.

3. Use Links to Navigate Through Pages

APIs should use links to allow users to navigate through pages. This makes it easier for users to navigate through the dataset, and provides them with a more intuitive way to access the pages.


Pagination is an important feature in APIs that allows developers to retrieve large datasets efficiently, flexibly and with a better user experience. By using pagination parameters consistently and returning the total count of results, developers can ensure that their APIs are easy to use and integrate with. Using links to navigate through pages can make paging more intuitive for users. Pagination can speed up API performance, improving the accuracy and speed of responses users receive.


Should I paginate my API?

As a developer, one crucial decision you need to make when designing your API is whether or not to paginate your API. Paginating an API means breaking down the response into smaller, more manageable pieces, which makes the data more accessible and easier to process. Essentially, pagination provides a mechanism for controlling the amount of data being transferred in each API call.

The main reason for paginating an API is to improve performance and usability. By limiting the size of the response, you’re able to reduce the amount of data retrieved from the server for each request, and use less bandwidth. This approach can make your API more responsive, and the user experience for your consumers much smoother. If you fail to paginate your API, then there is a high chance that you will be overloading your network and server, which may lead to slow response times, increased server load, and eventually, server crashes.

Another benefit of paginating an API is storage. If you’re working with large amounts of data, storing everything on one page may not be the best idea. You can store fewer records on a page to avoid overloading memory, which will keep response times fast and the data safe.

While paginating an API has its benefits, it is essential to design the pagination process correctly. The amount of data you should include on each page depends largely on your content and what makes sense in context. A good practice is to offer some parameter for pagination control, such as limiting the number of items that can be retrieved for a single request.

Pagination is a vital practice for designing an API that provides a great user experience. It is a crucial tool to optimize your network, storage, and server response time. By providing pagination parameters within your API, you make it easier for developers and end-users to manage the data requested from your API, leading to faster software development, better user experience, and overall happier customers.

What are the two types of pagination?

Pagination is a technique used to divide large sets of data into smaller chunks or pages to make them easier to navigate or display. It is a common problem faced by developers to deal with the issue of pagination. In the realm of web development, there are mainly two types of pagination methods — Offset and Cursor. Both methods have their own characteristics, benefits, and limitations that make them appropriate for different scenarios.

Offset pagination is one of the oldest pagination techniques, applied widely in RDBMS (Relational Database Management System) and implemented immediately by many ORMs (Object Relational Mapping) libraries such as Hibernate. In offset pagination, you divide the results into fixed-sized pages. These pages are numbered, and each page has a fixed number of records. For example, if you have 10000 records and you want to show 20 records on each page, the first page displays records 1-20, the second page displays records 21-40, and so on. It operates by using two parameters, page number, and page size and skips over the number of records specified by the (page-1) x page size formula to fetch the appropriate subset of records for the requested page.

Cursor pagination, also known as keyset pagination, aims to solve the issues caused by offset pagination such as large data sets, slow performance, and duplicate records. It is an alternative strategy that doesn’t rely on offsets but uses cursors or markers to keep track of where the pagination begins. Cursor pagination uses the sorting order of the data. Instead of skipping records, the cursor is updated with each subsequent query to identify the starting position of the next query. It operates by using parameters like limit and an ordering key. One main advantage of cursor pagination is that it can handle large amounts of data properly and avoids duplicate records, even when the data is modified in between pagination queries.

Both Offset and Cursor pagination strategies have their own strengths and specific use cases. Offset pagination is a simple pagination technique that is suitable for small volume, sorted, and stable data sets. Cursor pagination, on the other hand, is more efficient for working with huge, sorted, and dynamic data sets. Knowing which method to use depends ultimately on the individual needs of your application.

What is benefit of pagination?

Pagination is the technique of separating web content into multiple pages. It is implemented to break up lengthy pages into smaller, more manageable pages that can be viewed easily. The benefits of pagination are numerous, and they have significant implications for website design.

One of the most significant benefits of pagination is that it allows users to quickly view all of the content. In long web pages, users often lose track of where they are. The next page is easily accessible and visible, allowing users to pick up where they left off without having to scroll endlessly. Pagination also provides a clear indication of how much content there is and aids in orientation for users.

Another benefit of pagination is that it is more user-friendly than infinite scrolling. Many websites, particularly on mobile devices, use infinite scrolling to provide users with a seamless scrolling experience. However, it can be difficult for users to keep track of their location on the page. This can lead to increased frustration and a more difficult user experience. Pagination, on the other hand, provides a more structured approach to viewing content and is easier for users to navigate.

Pagination also allows users to bookmark specific content or location pages. As previously mentioned, users often lose their place when scrolling through lengthy pages. With pagination, users can easily bookmark content or location pages and return later without having to navigate through the entire page.

Furthermore, pagination can also have SEO benefits. Search engines like Google place a premium on fast-loading websites and pages. By implementing pagination, web designers can reduce page load times and improve their website’s ranking in search engine results.

Pagination is a critical technique used to increase website usability and improve user experience. It provides users with a clear navigation structure, aids in orientation, and increases the likelihood that users will engage with all of the content on a web page. Pagination is particularly useful for websites with long-form content, such as blogs, articles, and e-commerce product lists. By using pagination, designers can create a more user-friendly website that engages visitors and keeps them coming back.
