Pagination

Traverse through ChatKitty collections efficiently with pagination.

ChatKitty paginates all collection resources. Requesting a resource collection returns the first page of the collection optionally with HAL hypermedia links to subsequent pages if more pages are available.

Traverse the page links to iterate through a collection.

Properties

Embedded properties

A page resource embeds a slice of a resource collection in a JSON array property with the same name as the resource collection. For example, with a collection of users resources, the resource collection name would be users, and the page would include a JSON array in its _embedded property named users, as per the HAL specification.

  "_embedded": {
    "users": [
      {
        "id": 1,
        "name": "[e-mail]",
        "displayName": "Jane Doe",
        "_links": {
          "self": {
            "href": "https://api.chatkitty.com/v1/applications/1/users/1"
          },
          "channels": {
