Create a channel in a workspace
POST /api/workspaces/{workspaceId}/channels
Creates a channel in a workspace. An email channel is provisioned after the call returns and moves through the pending statuses of its inbound_mode to active; an inbox_api channel waits in draft until its mailbox is connected in the dashboard. A chat channel is active at once. A voice channel is active at once when its phone number is, and pending_activation while the number is in review with the carrier. For voice channels, bind a provisioned phone number via phoneNumberId. The created channel record is returned; an email channel’s record carries what the mode needs set up outside oHallo: config.inbound_address where oHallo generates it, and config.dns_records where the mode has records to publish.

Request Body
Section titled “Request Body ”object
The type of channel to create.
Example
emailA human-readable name for the channel. Leading and trailing whitespace is trimmed.
Example
Support EmailChannel-specific configuration, validated against the shape for channelType: the email channel config for email, the chat channel config for chat and the voice channel config for voice_phone. An email channel needs one; the other types accept an empty object, the default.
object
The configuration of an email channel. inbound_mode decides how mail reaches oHallo and which fields the channel needs. A config without inbound_mode is read as subdomain, with inbound_address taken from from_address. While it provisions the channel, oHallo adds keys of its own, marked read-only: the inbound_address it generates, the DNS records to publish, and error_message when provisioning fails. A channel is created in subdomain, forwarding, inbox_api or mail_routing_rule; another inbound_mode on create, or a new mode on update other than subdomain, forwarding or inbox_api, answers 422.
object
A subdomain given to oHallo, for example help.example.com, receives the mail itself. Publish the records in dns_records on it. The channel turns active once the domain is verified. The addresses are on a subdomain of a registrable domain, as the Public Suffix List draws it: an address on a registrable domain itself, such as support@example.com or support@example.co.uk, answers 422 with the message on that address, since an MX record there would receive all of the domain’s mail.
object
subdomain, which is also how a config without inbound_mode is read.
The address customers write to and replies come from: an address on the subdomain.
Example
support@help.example.comThe address mail is received at, the same as from_address. Required when inbound_mode is sent; without inbound_mode it is taken from from_address.
Example
support@help.example.comThe domain the DNS records belong to, written by oHallo.

On a mail_routing_rule channel, the domain the DKIM records belong to.
Why provisioning failed, when the channel’s status is error and the reason is known.
A routing subdomain receives mail at oHallo, and a mail-flow rule at the current mail provider redirects the mail for from_address to inbound_address on it. Publish the records in dns_records on the routing subdomain. Customers keep writing to from_address, and the channel turns active when the first redirected message arrives. A channel in this mode is read back with it and keeps it on update; a create in it answers 422.
object

On a mail_routing_rule channel, the domain the DKIM records belong to.
Why provisioning failed, when the channel’s status is error and the reason is known.
The mailbox stays where it is and forwards its mail to inbound_address, an address oHallo generates when the channel is created. No DNS records are needed. Replies are sent from an oHallo address, with from_address as their reply-to address. The channel turns active when the first forwarded message arrives.
object
The address customers write to.
Where the mailbox of from_address is hosted.

Why provisioning failed, when the channel’s status is error and the reason is known.
A mail-flow rule in Microsoft 365 or Google Workspace redirects the mail for from_address to inbound_address, an address oHallo generates when the channel is created. DKIM records on the domain of from_address sign the replies; dns_records lists them once provisioning has requested them. The channel turns active when the first redirected message arrives. A channel is created in this mode with from_address and mail_provider (office365 or google); an update into it answers 422.

On a mail_routing_rule channel, the domain the DKIM records belong to.
Why provisioning failed, when the channel’s status is error and the reason is known.
OHallo reads and sends through a Microsoft 365 mailbox. The mailbox is connected in the dashboard: open the channel under Settings, Channels and choose Connect, which signs in to the mailbox’s provider. The channel stays in draft until then, and turns active when the mailbox is connected. A connected mailbox keeps its from_address, inbound_address, mail_provider and inbound_mode.

object
floating is a launcher in a corner of the page that opens the chat, sidebar is a full-height panel at the side of the page, and inline is a section inside the page.

Questions shown in the empty chat; choosing one sends it as the visitor’s first message. Inline mode only.
How the team follows up when a chat visitor needs it. A channel that holds handover reads it alone.
object
When a visitor’s question needs the team and an email address for the visitor is known, the assistant passes the chat to the team by email: an email conversation with the visitor opens, or an open one continues, linked to the chat, in the email channel chosen for follow-ups or, when none is chosen, the workspace’s only email channel. The visitor receives an email in it, unless a team member holds that conversation or has paused the assistant on it. When phone is true and the visitor leaves a number for a call, a callback request is recorded instead.
With true, a phone number the visitor leaves for a call from the team becomes a callback request in Callbacks. With false, none is recorded.
In the account’s own words, which questions go to the team. The assistant reads it when it decides which questions to pass to the team.

object
The line’s language, as a language code: one of the brand’s supportedLanguages, or the workspace’s operatingLanguage. It is stored as the canonical code (no is stored as nb). Without it, or with null, the line takes the workspace’s operating language. A language outside those answers 422 and nothing is saved.
Example
svThe opening line callers hear on this number, in place of the workspace’s greeting. A new or changed line is saved only with welcomeGreetingAttested: true in the same request (EU AI Act Article 50), and its wording must mention the assistant in the line’s language; otherwise the request answers 422 with code greeting_attestation_required or greeting_must_mention_ai. A confirmation covers the line’s language: after the line moves to another language, the line is confirmed again in that language.
How soon the voice starts to speak a reply. sentence, the default, waits for a whole sentence, which sounds most natural; token starts on the first words and answers sooner.
Policies left out of calls on this number. A call draws on every approved policy of the workspace except these.

Example
{ "inbound_mode": "subdomain", "from_address": "support@help.example.com", "inbound_address": "support@help.example.com"}Whether the channel is enabled. Defaults to true.
Example
trueEU AI Act Article 50 confirmation for a greeting override in config.welcome_greeting on a voice channel: the same rule as attested on a workspace greeting (voiceGreetings). A new or changed override is refused with 422 and code greeting_attestation_required unless this is true, and refused with code greeting_must_mention_ai when the wording does not mention the assistant. An override without a valid confirmation is replaced at call time by the standard opening line.
Example
trueThe provisioned phone number to bind. Required when the channel type is voice_phone, and not permitted for other types.

Example
emailHuman-readable name.
Example
Support EmailWhere the channel stands. draft: set up but not live; an inbox_api email channel stays in draft until its mailbox is connected in the dashboard. pending_dns: a subdomain, subdomain_with_redirect or mail_routing_rule email channel waits for its DNS records to be published and to resolve; a mail_routing_rule channel waits here until its DKIM records are verified, for up to 72 hours, after which it moves to error. pending_verification: the channel’s DNS records resolve, and oHallo is completing the verification of its domain. pending_setup: a mail_routing_rule or subdomain_with_redirect email channel waits for the first message its mail-flow rule redirects, and turns active when it arrives. pending_inbound: a forwarding email channel waits for the first forwarded message, and turns active when it arrives. pending_activation: a voice channel waits while its phone number is in review with the carrier, and turns active when the number is approved. active: the channel receives and sends messages; a successful connectivity test also sets it, on every channel but a mail_routing_rule one. error: provisioning failed, a connectivity test failed on an active channel, or a connected mailbox needs to be connected again; after a provisioning failure config.error_message says why when the reason is known. The retry endpoint provisions an email channel again, and a connected mailbox is connected again in the dashboard. inactive: a connected mailbox was disconnected, and the channel receives and sends nothing until the mailbox is connected again. deprovisioned: the channel was deleted; channel lists leave it out, and a read by id returns it.
Example
activeWhether the channel is enabled.
Example
