The account's app answers a manifest

POST /carrier-accounts/{carrierAccountId}/manifests/{manifestId}/answer

The account's app answers a manifest: lodged with the carrier (its id there), after which none of its consignments can be voided, or refused with the reason, which frees them for the next manifest.

Appends fulfillment.manifest-lodged or fulfillment.manifest-refused. Idempotent by state: a manifest is answered once, so the same answer again is acknowledged and a different one is 409 ManifestNotInState.

Access

Requires shipping:write.

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

Retries

Idempotent by state: a manifest is answered once, so the same answer again is acknowledged and a different one is 409 ManifestNotInState.

Why every write carries a key: Idempotency and retries.

Facts appended

fulfillment.manifest-lodged
fulfillment.manifest-refused

What a fact is: Facts and the journal.

AI agent tool

No agent tool. only the account's shipping app answers a manifest, with what its carrier said

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
`NotACarrierApp` reason	Only a carrier app may call this.	Call it with the carrier app's token.
`CarrierAccountNotYours` carrierAccountId	This carrier account belongs to another app.	Call it with the app that keeps the account.
`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.

`404`

Refusal	What it means	What to do
`CarrierAccountNotFound` carrierAccountId	No such record in this organization.	Check the id in the path or the body.
`ManifestNotFound` manifestId	No such record in this organization.	Check the id in the path or the body.

`409`

Refusal	What it means	What to do
`ManifestNotInState` manifestId, status, expected	The manifest is not in a state this call accepts.	Read the record: its `status` says where it stands, and `expected` the states this call accepts.
`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.

`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 shortly.
