Page-related operation queuing with page instructions in Pega APIs

Pega APIs provide page instructions that you can use to make your application queue a list of page-related operations and send them to the server after the user performs a submit or a refresh. The server then runs the user operations in the order in which 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 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
If a page instruction is invalid, for example, if the listIndex that was specified for a page list does not exist, the API returns an HTTP 400 error in the response body. To view the debugging information, you can change the value of the DebugPegaAPI dynamic system setting to True. For more information, see Editing a dynamic system setting.
