You can now specify a queue of page instructions for user operations on embedded pages, page lists, and page groups in Pega Digital Experience APIs. The page instructions allow your client application to more accurately model users' actions.

Pega Digital Experience APIs support the following operations:

• For embedded pages: DELETE, REPLACE, and UPDATE.
• For page lists: DELETE, REPLACE, UPDATE, APPEND, INSERT, and MOVE.
• For page groups: DELETE, REPLACE, UPDATE, and ADD.

Each time a user performs an operation, such as modifying a row in a table, the client application queues it. When the user completes the form, the client application passes all the operations via the page instructions to the server, and the server plays back the operations in the order that the user made them. For example, if the user edited a row (UPDATE), appended a row (APPEND), and inserted a row (INSERT), the client application passes only the instructions and fields for those three rows to the server instead of the entire table.

The following image shows the page instructions that are included in the Model Schema section of the POST /assignments{ID} Pega Digital Experience API.

The following Pega Digital Experience APIs include the page instructions:

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