Give a person or a company store credit by hand

POST /credit

Give a person or a company (holderId) store credit by hand, in one currency, with the reason for the record; answers the account as it now stands.

The books post it as store credit given against customer credit. Appends fulfillment.credit-issued. creditId (a caller-minted crd_…) is required and is the idempotency key: a retry with the same id is acknowledged and gives the credit once.

Access

Requires payments:write.

How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.

Retries

creditId (a caller-minted crd_…) is required and is the idempotency key: a retry with the same id is acknowledged and gives the credit once.

A retry with the same key answers 201, with what the first call recorded.

Why every write carries a key: Idempotency and retries.

The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: fulfillment-manager.openapi.json. Base URL https://fulfillment.getmanifold.io.

Errors

Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.

`401`

Refusal	What it means	What to do
`Unauthorized` reason	The token is missing, expired or not one Manifold issued.	Get a fresh token and send the call again.
`TokenAlreadyUsed` tokenId	A single-use app token was already spent.	Mint a new token for this call.

`402`

Refusal	What it means	What to do
`SubscriptionRequired` status	The organization's subscription has lapsed, so writes are refused.	An owner settles billing. Reads still work meanwhile.

`403`

Refusal	What it means	What to do
`TenantRequired` userId	The token names no organization.	Choose the organization, then get a new token.
`ScopeRequired` required	The token's roles do not grant the scope this call needs.	Ask an owner or admin for a role that grants it.

`409`

Refusal	What it means	What to do
`MirroredFromSource` source	This area is fed by your source system until the organization goes live.	Make the change in the source system, or go live first.

`502`

Refusal	What it means	What to do
`InventoryUnavailable` reason	The inventory service did not answer, so nothing changed.	Send the same request again, with the same key.

`503`

Refusal	What it means	What to do
`RequestLogUnavailable` tokenId, reason	The service could not record the request, so it did nothing.	Send the same request again, with the same key.
