Creates a mailbox. The address is local_part@domain. The domain defaults to inbox.ai, Bird's shared mailbox domain, where creating the mailbox claims the address for your organization. It is first come, first served, and reserved to your organization even after the mailbox is deleted. You may instead name one of your own domains. A domain enabled for receiving email delivers to the mailbox directly. A domain this workspace has verified (its status is verified) that is not set up for receiving gives the mailbox a forwarding_address to forward its mail to. If another workspace receives the domain's mail, creation fails with E17009. An omitted local part is generated. On a custom domain, addresses of deleted mailboxes are quarantined for 30 days and remain reserved for your workspace.

Corps de la requête

local_part
string

The local part of the mailbox address (the part before @). Letters, digits, dots, underscores, and hyphens. Stored lowercase. On the shared inbox.ai domain, separators must sit between letters or digits. Leading, trailing, and repeated separators are not allowed. Reserved names such as postmaster and abuse are unavailable. Choosing your own local part uses one of your plan's custom-handle allowance slots; generated addresses remain available. Omit this field to generate a random local part.

domain
string

The domain the address lives under. Defaults to inbox.ai, our shared mailbox domain. Creating a mailbox claims the shared address for your organization on a first-come, first-served basis. The address remains reserved to your organization after the mailbox is deleted. You can instead use one of your own domains. On a domain enabled for receiving, mail arrives directly. On a domain this workspace has verified (its status is verified) that is not set up for receiving, the mailbox gets a forwarding_address: forward mail for the address there from your current email provider, with no MX change. If another workspace receives the domain's mail, creation fails with E17009.

display_name
string

Display name used as the sender name on mail from this mailbox.

default_reply_to
string

Default Reply-To address stamped on mail sent from this mailbox.

receive_policy
string

Which inbound mail the mailbox accepts:

  • open: Accepts everything not blocked by a rule.
  • replies_only: Accepts only replies to messages this mailbox has sent. A reply must match a message the mailbox sent. Landing in an existing thread by itself does not count.
  • allowlist: Accepts only senders matching an allow rule.
  • drop: Stores nothing.

Possible values: open, replies_only, allowlist, drop

retention_tier
string

How long message metadata, extracted text, and attachments are kept. Original bodies and inbound raw MIME are limited to 30 days on every tier. Longer tiers require a plan that includes them.

Possible values: 30d, 90d, 1y

metadata
object

Your own key/value data to attach to the mailbox. Up to 2 KB. Keys starting with __bird are reserved.

Contenu de la réponse

id
string
obligatoire

Mailbox ID.

address
string
obligatoire

The mailbox's email address. Immutable once created.

forwarding_address
nullable string
obligatoire

An address we generate on our receiving domain when the mailbox is created on a domain not set up for receiving with us. Forward mail for address here from your current email provider, and it lands in this mailbox. Replies still go out from address. Immutable. It stops receiving while the mailbox is deleted, works again with the same value after a restore, and keeps working if you later enable receiving on the domain. null on mailboxes created on the shared domain or on a domain already enabled for receiving.

display_name
nullable string
obligatoire

Display name used as the sender name on mail from this mailbox. null when unset.

default_reply_to
nullable string
obligatoire

Default Reply-To address stamped on mail sent from this mailbox. null when unset.

receive_policy
string
obligatoire

Which inbound mail the mailbox accepts:

  • open: Accepts everything not blocked by a rule.
  • replies_only: Accepts only replies to messages this mailbox has sent. A reply must match a message the mailbox sent. Landing in an existing thread by itself does not count.
  • allowlist: Accepts only senders matching an allow rule. Replies to prior outbound mail are always admitted unless blocked.
  • drop: Stores nothing.

Possible values: open, replies_only, allowlist, drop

state
string
obligatoire

Lifecycle state. active means the mailbox can send, receive, and expose conversations. suspended pauses sending, conversation reads, and events; inbound mail is retained with the blocked label until you resume it.

Possible values: active, suspended

channel
string
obligatoire

The channel this mailbox receives on. Always email.

Possible values: email

owner
object
obligatoire

The principal that owns the mailbox. Always the workspace.

Afficher les attributs enfants
inbound_address_id
string
obligatoire

The underlying inbound address that receives this mailbox's mail.

retention_tier
string
obligatoire

How long message metadata, extracted text, and attachments are kept. Original bodies and inbound raw MIME are limited to 30 days on every tier.

Possible values: 30d, 90d, 1y

message_count
integer
obligatoire

Number of retained messages across all threads.

thread_count
integer
obligatoire

Number of retained threads.

size_bytes
integer
obligatoire

Stored bytes across the mailbox's retained messages: subject, preview, extracted text, and attachment bytes. Message bodies and raw MIME expire after 30 days and do not count. Maintained with each message written or deleted, so the value is current; messages stored before the counter existed are not counted.

unread_thread_count
nullable integer

Number of threads with unread messages in this mailbox, excluding trash. null on create/update responses.

metadata
object
obligatoire

Your own key/value data attached to the mailbox. Up to 2 KB. Keys starting with __bird are reserved.

local_part_generated
boolean
obligatoire

Whether we generated the local part of the address. false means a custom handle was chosen at creation. On the shared inbox.ai domain a custom handle counts against your plan's custom-handle allowance.

created_at
string
obligatoire

When the mailbox was created.

updated_at
string
obligatoire

When the mailbox was last updated.

deleted_at
nullable string

When the mailbox was deleted, or null if active. Deletion stops receiving; restore is available for 30 days unless permanent erasure has started.

next
array of object

What to do next with this mailbox. The response that creates it suggests subscribing to the mail it receives; other reads of one mailbox return an empty list, and lists omit it.

Afficher les attributs enfants
next.kind
string
obligatoire

What you do about this step.

  • operation: call the operation named in operation, then read again.
  • external: act somewhere this API does not reach, then read again.
  • wait: nothing is asked of you, so read again later.
  • terminal: nothing you do resolves this, so stop retrying.

Tolerate a value you do not recognize: show the description and offer no action.

Possible values (may grow over time): operation, external, wait, terminal

next.description
string
obligatoire

A short, human-readable label for the step, suitable for display.

next.operation
string

The operationId to call. Present only when kind is operation. The operation's own schema says how to call it; this says only which one, and what to address it with.

next.params
object

The parameters that address the operation, by name: {"sender_id": "…"} for an operation on /v1/sms/senders/{sender_id}/requirements. A parameter the operation takes in its query string is given the same way, so an operation addressed as ?subject_id= carries {"subject_id": "…"}. Every parameter the call needs is here, whether its value came from the thing you were acting on or is fixed for this step, so you can make the call from this object alone. Present only when kind is operation and the operation names a subject. A request body, when the operation takes one, is described by the operation's own schema and never appears here.

next.url
string

A URL to open. Present only when kind is external, and only when the step has one. An external step whose description says to go and do something with no URL to open is normal.
