Set which CSV column feeds which target field

PUT /imports/{jobId}/mapping

Appends import.mapped. Rejected with 422 InvalidMapping if a field is unknown, two columns claim the same field, or a required field is unmapped; 409 ImportNotReady once the job is committed (queued), running or finished. Idempotent by content: re-mapping a staged job replaces the mapping whole, so a retry lands on the same mapping.

Access

Requires imports:write.

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

Retries

Idempotent by content: re-mapping a staged job replaces the mapping whole, so a retry lands on the same mapping.

Why every write carries a key: Idempotency and retries.

Facts appended

import.mapped

What a fact is: Facts and the journal.

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.

`404`

Refusal	What it means	What to do
`ImportJobNotFound` jobId	No such record in this organization.	Check the id in the path or the body.

`409`

Refusal	What it means	What to do
`ImportNotReady` jobId, status, expected	The import 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.

`422`

Refusal	What it means	What to do
`InvalidMapping` reason, field	The column mapping does not fit the target. `field` names the problem.	Map every required field once.

`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.

How refusals work everywhere: Errors.
