concessions.assign

What it does

Assign a concession offer to an email: the person who accepts an agreement under it receives the offer. An email can be reassigned until it is used.

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.assign 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 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
`offerId`	string	Yes	Minimum length: `1`. Maximum length: `200`. Example: `"cof_01"`.
`email`	string	Yes	Minimum length: `3`. Maximum length: `320`. Example: `"founder@example.com"`.

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.
