Assign Reviewers to nominations

POST/v1/organization/{orgId}/awards/workspace/programs/{programId}/assign

US Region: https://public-api.sessionboard.com · EU Region: https://public-api-eu.sessionboard.com

Gives every submitted nomination perSubmission Reviewers (default 3, never more than the program has), least-loaded Reviewer first. Assignments already made are kept, and a pair that was unassigned earlier is restored rather than duplicated. Reviewers with a conflict of interest are still caught by the review portal's own check. created is how many assignments were added or restored; with no Reviewers or no submitted nominations it is 0 and per_submission is left out. Sends nothing. Requires write:awards; the token's user needs the Awards update permission and must manage the program. Refused for a key restricted to particular events. Also at POST /v1/awards/workspace/programs/{programId}/assign.

• ORG_WIDE_TOKEN_REQUIRED: the key is restricted to particular events. The Awards workspace covers every awards program in the organization, so use a key without an event restriction.
• FORBIDDEN with code: trial_ended or code: plan_ended: the organization's self-serve Awards plan is read-only (the trial ended, or the plan was canceled or is unpaid). Everything can still be read; choose a plan to make changes.
• FORBIDDEN with no code: the token's user is not an active member of the organization, lacks the Awards permission the operation needs, does not manage the program, or (for the setup answers) is not an organization admin.

These operations do not return enterprise_only; the Enterprise-only items are listed by GET /v1/organization/{orgId}/awards/workspace/enterprise.
