# approveApprovalRequest

mutation · in the family [Approval request](/reference/approval-request/)

## What it does

Grant a pending approval request — your authority unblocks the requester’s act.

Approve a pending ApprovalRequest: the approver's resolved tier rank must be ≥ requiredTier (AUTHZ/INSUFFICIENT) and the approver can NEVER be the requester (AUTHZ/SELF_APPROVAL — STRICT, no relaxation); a TTL-expired pending refuses CONFLICT/EXPIRED and lazily expires. Requires the unrestricted capability + the record's CURRENT revision. On approval the requester RETRIES the identical gated call — the retry consumes the approval by fingerprint.

## Careful

You are lending your authority to that exact act — the record names you. Never-self-approve holds.

## Who may call it

Capability area: **Register approvals** — Approving or denying the requests raised at a register.

- Owner
- Manager
- Associate Manager
- An API key whose scope allows `api:approveApprovalRequest`

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | yes | The id of the record. |
| `revision` | [ID](/types/#scalars) `ID!` | yes | The revision id you read on the record; the change is refused if an edit landed in the meantime. |
| `reason` | [String](/types/#scalars) | no | No further notes. |

## Returns

[ApprovalRequest](/types/ApprovalRequest/) `ApprovalRequest!` — An ApprovalRequest — the real-time, human-approver, in-session authorization of ONE POS action exceeding the requester's authority (DISTINCT from the async ChangeRequest). The blocked action stays blocked until resolved; short TTL (expiresAt — a touch past it refuses CONFLICT/EXPIRED and lazily expires the request). The request binds a fingerprint (action, targetId\[, valueMinor]) + the requester: on approval, RETRYING the identical gated call finds + consumes the approval by fingerprint (single-use — the marker releases in the retry's own transaction). Never self-approve (AUTHZ/SELF_APPROVAL); an under-ranked approver is AUTHZ/INSUFFICIENT.
