Steps
Authenticate with a 3-legged token; Submittals v2 endpoints are project-scoped under https://developer.api.autodesk.com/construction/submittals/v2/projects/{projectId}/ and explicitly do not work against BIM 360 projects.
Retrieve item types and spec sections first, then list items with GET items, which supports filtering.
Create a submittal item with POST items, including a templateId to apply a predefined review workflow with its steps/tasks.
Set a manager-assigned number via customIdentifier / customIdentifierHumanReadable; call GET items:next-custom-identifier to preview the next number and POST items:validate-custom-identifier before submitting to avoid collisions.
Fetch item attachments with GET items/{itemId}/attachments and review responses with GET responses.
Use the item-transition write endpoints (added alongside POST items/POST specs) to move an item through its review states.
Known gotchas
Submittals was read-only for a long time; write endpoints (POST items, POST specs, custom-identifier validation) are newer, so older code samples/SDKs may only show GET calls.
customIdentifier and customIdentifierHumanReadable are separate fields from the system-generated submittal number — set both or the number displays inconsistently in the ACC UI.
These v2 endpoints are not usable against BIM 360 projects, only ACC/Forma-migrated ones.
