# concessions.create_offer

## What it does

Create a concession offer: a discount the business gives customers off what their agreement would otherwise charge, with its purpose (acquisition, retention, service or research) and attribution (a campaign name, a partner party). Assign it to emails with concessions.assign; a contract takes it with contracts.create's `concession`. Posts nothing.

## Before you send it

An authorized OAuth connection may call it, including a headless client. Effective membership, application grant and token permissions still apply. Describe `concessions.create_offer` through `GET /v1/catalog/commands/{name}` before acting.

This command does not accept `source_document_id` in its envelope. Any input evidence requirements remain as documented below.

## Inputs

Put these fields inside the envelope's `input` object. The outer envelope names the command, a stable `idempotency_key` and `effective_at`; [request and recovery rules](/docs/api/) explain those separately. Use exact minor-unit integer strings for monetary fields. Take existing IDs from prior reads or command results; choose a new identity only where the command asks for one.

Required means required within its containing object; an optional parent can be omitted.

| Field | Type | Required | Meaning and accepted values |
|---|---|---|---|
| `name` | string | Yes |  Minimum length: `1`. Maximum length: `200`. Example: `"Design partner free year"`. |
| `purpose` | string | Yes |  Choose `"acquisition"`, `"retention"`, `"service"`, `"research"`. Example: `"research"`. |
| `campaign` | string | No |  Minimum length: `1`. Maximum length: `200`. Example: `"design partners"`. |
| `partnerPartyId` | string | No |  Minimum length: `1`. Maximum length: `200`. |
| `partnerContractId` | string | No |  Minimum length: `1`. Maximum length: `200`. |
| `discount` | object | Yes |   |
| `discount.basisPoints` | integer | No |  Minimum: `1`. Maximum: `10000`. Example: `10000`. |
| `discount.amount` | string | No |  Pattern: `"^[1-9][0-9]*$"`. |
| `discount.months` | integer | No |  Minimum: `1`. Maximum: `1200`. Example: `12`. |
| `maxRedemptions` | integer | No |  Minimum: `1`. Maximum: `1000000`. |
| `emails` | array | No |  Items: string. Maximum items: `50`. |
| `code` | string | No |  Minimum length: `2`. Maximum length: `40`. |
| `system` | string | No |  Minimum length: `2`. Maximum length: `40`. |
| `validFrom` | string | No |  Format: date. |
| `validUntil` | string | No |  Format: date. |
| `eligibility` | object | No |   |
| `eligibility.emailDomain` | string | No |  Minimum length: `1`. Maximum length: `200`. |

## After acceptance

When the command emits events, its documented effects and receipt are recorded in the command transaction. The response returns `commandId`, `replayed`, the command-specific `result` below and emitted `events` with their IDs and CIDs. A command is not automatically a cash movement or revenue recognition: use the behavior above to determine what this command records.

Inspect `result` and the affected records or reports before continuing. Save returned identifiers for later calls. Fetch `GET /v1/commands/{id}` with `commandId` to recover the accepted receipt; retry the same intent with the same idempotency key if the response was lost. Some commands can succeed with `events: []` and return a transient result and `commandId` without persisting a receipt. A lookup of that ID can return null; retain the returned result and verify the affected record. Retrying can re-evaluate the current state rather than replay a stored result. A domain `no_change` is a separate success outcome with no persisted receipt.
