Working with large sets of data can be a daunting task in development. APIs are a powerful tool for retrieving and manipulating data, but when the data is too large to handle all at once, pagination comes to the rescue. Pagination is a technique used to retrieve large sets of data from an API in smaller, more manageable chunks. This is important because large amounts of data can be difficult to work with, especially when it comes to displaying it on a website or application. Pagination allows developers to break down the data into smaller pieces, making it easier to load, display, and navigate.
We will take a step-by-step approach to understand how pagination can be used to streamline data retrieval, improve performance and enhance user experience. Here, we shall take HubSpot API as reference to explain pagination.
Pagination with Step-by-Step Guide
We can use either HTTP module with authorization or "Make an API Call" for pagination. Once you have added the authorization parameters and URL, you can start implementing pagination.

Start with the Repeater module in your scenario to iterate through all the contacts or other entities. To do this, input a higher value in the "Repeats" field of the Repeater module.

Connect the Get Variable module to the Repeater and provide any suitable name, say- "AfterKey Id"

Step 3 :
Run the Get Variable module and map the output variable in the HTTP module as shown below:
