You can use the page instructions provided in Pega APIs so that your application queues a list of page-related operations and sends them to the server after the user performs a submit or refresh. The server then plays back the user operations in the order that they were received. For example, if the user edited a row, appended a row, and inserted a row, your application passes only the instructions and fields for those three rows to the server instead of the entire table.

The page instructions are provided in the following Pega APIs:

• PUT /casetypes/{ID}/refresh
• POST /cases
• PUT /cases/{ID}
• PUT /cases/{ID}/actions/{actionID}/refresh
• POST /assignments/{ID}
• PUT /assignments/{ID}/actions/{actionID}/refresh
