The response from a web service request will change depending on the type of request sent. Some responses contain an array of information, others only HTTP Status codes. The example return arrays shown have been decoded from JSON for readability.

Read (GET)

Read, or GET requests, return an array of information, including any records found to match the given criteria. The response array is structured to handle paginated requests, and includes a 'list' of the records on the current page.

Return Attributes

self: The current page being viewed

first: The first page in the data set

last: The last page in the data set. If this matches the value in first, the data set has been returned in full in the list option.

next: The next page in the data set, following the current page, self

prev: The previous page in the data set, preceding the current page, self

list: The data range of the current self request page
