Invitations

Enforced atWhen this policy is checked: while someone tries to open, while they create or change an invitation or hold, or after a denial (notify only).

Authoring-time

TiersWhere an admin can set this policy: the whole organization, one integration, or the physical device when the connector supports a device steward.

OrgIntegrationDevice

EnforcementHow a configured row behaves. Enforce blocks. Require approval opens an admin inbox when the type supports it. Audit only records and never blocks.

Enforce

DefaultWhat happens when no row of this type is configured.

System default is 86400 (1 day) when unset. Org policy may raise the share cap up to 31536000 (365d).

Applies only when creating a share (kind=share). The system default cap is 1 day. An org share_max_duration policy may raise that cap up to 1 year. Effective duration is the min of invitation_max_duration and the share cap. The request is rejected rather than silently shortened.

When it is enforced

Evaluated when someone creates or updates an invitation, hold, or share. Requests that would exceed the limit are rejected — they are not silently rewritten.

Where to set it

Settings → Policies (org), the integration Policies tab, or — on PalGate — the device steward Policies tab.

Policies never grant access. See thepolicies architecture guidefor how org, integration, and device tiers combine.

Arguments

The config object on create/update. Shared row fieldsenforcement (enforce, require_approval,audit_only) and enabled apply to every type;audit_only and disabled rows never block.

Name	Type	Required	Values	Description
max_seconds	integer	Yes	—	Maximum share lifetime in seconds. Must be greater than 0 and at most 31536000 (365d).
output	string or integer	No	—	Optional channel or output id. When set, the policy binds only that output. When omitted, it binds every output of the tier target. A scoped row does not apply when the acting output is unknown.

How overlapping rows combine

Minimum of max_seconds across applicable share_max_duration rows (else 86400), then min with invitation_max_duration. Reject, do not clamp.

Example

A 48-hour share is rejected when the cap is 24 hours.
