Start sending from the organization's own domain

POST /settings/domain

Start sending from the organization's own domain (ridgeline.com): Manifold registers the domain with its mail provider and answers the DNS records to create at the domain's DNS host — three DKIM CNAMEs, an MX and an SPF TXT on the bounce subdomain bounce.<domain>, and a DMARC TXT recommended where the domain has none.

Mail keeps going from Manifold's address until the records are found (POST /settings/domain/check). Appends notifications.sending-domain-added. 409 SendingDomainUnavailable for a domain another organization sends from or one of Manifold's own. Idempotent by state: adding the domain the organization already has answers it as it stands and appends nothing, and any other domain while one is held meets 409 SendingDomainExists — remove it first.

Access

Requires settings:write.

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

Retries

Idempotent by state: adding the domain the organization already has answers it as it stands and appends nothing, and any other domain while one is held meets 409 SendingDomainExists — remove it first.

Why every write carries a key: Idempotency and retries.

What a fact is: Facts and the journal.

AI agent tool

No agent tool. Sending from the merchant's own domain means records at their DNS host: the owner's work in Settings › Notifications, where the records are shown to copy.

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: notifications-manager.openapi.json. Base URL https://notifications.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
`SendingDomainExists` domain	The organization already sends from another domain.	Remove that domain first.
`SendingDomainUnavailable` domain, reason	Another organization sends from this domain, or it is one of Manifold's own.	Use a domain you own.
`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
`MailProviderUnavailable` reason	The mail provider did not answer, so nothing was sent.	Send the same request again shortly.
`RequestLogUnavailable` tokenId, reason	The service could not record the request, so it did nothing.	Send the same request again shortly.
