Steps
In the plugin bundle's plugin.xml manifest, add an access_request block listing each database table/field the plugin's API calls or PowerQueries need to touch.
Give each field entry a table, field, and access level (ViewOnly or FullAccess) attribute — omitting a field here, even one your code only reads, causes calls touching that field to fail.
For plugins that use PowerQueries, update the access_request to cover every field referenced anywhere in the query's SQL, not just the fields returned in the response payload.
After editing plugin.xml, reinstall/redeploy the plugin bundle through the PowerSchool admin Plugin Management console; a running installation doesn't pick up manifest changes automatically.
Have a district admin review and approve the plugin's updated data access request before the new field-level permissions take effect for API calls.
Known gotchas
A missing access_request entry doesn't surface as an obvious permissions error — it typically shows up as a 403 Forbidden on the specific API/PowerQuery call, which can look like an authentication bug rather than a manifest gap.
Access is declared per field, not per table — requesting FullAccess on one field doesn't implicitly grant access to other fields on the same table.
