# createExemptionCertificate

mutation · in the family [Exemption certificate](/reference/exemption-certificate/)

## What it does

Create a new customer’s tax-exemption certificate at your organization.

Capture an ExemptionCertificate; requires the unrestricted capability. The capture is immutable except caption/code/docRef — correct by revoke + re-capture (no revival from any terminal).

## Who may call it

Capability area: **Selling** — Ringing sales, serving customers and issuing invoices.

- Owner
- Manager
- Associate Manager
- Sales Associate
- Cashier
- An API key whose scope allows `api:createExemptionCertificate`

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `input` | [NewExemptionCertificateInput](/types/NewExemptionCertificateInput/) `NewExemptionCertificateInput!` | yes | No further notes. |

## Returns

[ExemptionCertificate](/types/ExemptionCertificate/) `ExemptionCertificate!` — A tax-exemption certificate — a captured legal document: a valid in-scope cert ZEROES tax at sale for its covered jurisdictions/categories (the calc consumes it; at-USE validity = status active ∧ not past expiresAt ∧ scope match — CONFLICT/EXPIRED per SPEC_ERRORS). Parent = the org group, FIXED AT BIRTH (the / customer host is a later REF, never a reparent). Capture is INLINE. The capture is IMMUTABLE except caption/code/docRef — correct anything else by revoking and re-capturing. active → expired is SCHEDULED; revoke and doom are the caller ops.

## Errors this call can answer

- `VALIDATION/INVALID` — Something in the request is not valid. ([VALIDATION](/errors/VALIDATION/))
- `AUTHN/REQUIRED` — Sign in to do this. ([AUTHN](/errors/AUTHN/))
- `AUTHZ/FORBIDDEN` — Your role does not allow this action. ([AUTHZ](/errors/AUTHZ/))
- `RATE_LIMIT/THROTTLED` — Too many requests in a short time. ([RATE_LIMIT](/errors/RATE_LIMIT/))
- `NOT_FOUND/*` — That record could not be found. ([NOT_FOUND](/errors/NOT_FOUND/))
- `CONFLICT/*` — The record’s state, or a change made in the meantime, does not allow this; the codes are on the CONFLICT page. ([CONFLICT](/errors/CONFLICT/))
- `VALIDATION/VERSION_REQUIRED` — The request did not say which app version it came from. ([VALIDATION](/errors/VALIDATION/))

## Dry run

Add `dryRun: true` to the request envelope (`extensions.at`) to rehearse this call: every check runs, the write is rehearsed against the current records and nothing is stored; the answer is the refusal a real call would give, or the record it would create. Every response to a rehearsal carries `dryRun: true`, so a rehearsed record is never mistaken for a saved one.
