We have an app called "Deliverables" in each of the workspaces (there are about 20+ workspaces). Each of these Deliverables have a number of Items under them. What is the best API to use to retrieve,
Thanks
Get all organisations
https://developers.podio.com/doc/organizations/get-organizations-22344
This will give you all ORG_IDs, associated to the user.
Select the ORG_IDs for which ORGs you want to deal with, or use all of them in loop.
Get all workspaces
https://developers.podio.com/doc/spaces/get-list-of-organization-workspaces-238875316 will return the list of workspaces for particular ORG_ID
Loop through workspaces to get apps
https://developers.podio.com/doc/applications/get-app-by-org-label-space-label-and-app-label-91708386
Get items from apps
https://developers.podio.com/doc/items/filter-items-4496747 will finally give you items in apps (again needs to be in the loop)
There is also alternative way you may try:
* Get all apps user has access to
https://developers.podio.com/doc/applications/get-all-apps-5902728
* Loop over apps and get items
https://developers.podio.com/doc/items/filter-items-4496747
