Deploy & domains

Publish project

Plan: Business or higher

Scope: projects:write

Builds and deploys the project. Returns 202 with the Deployment representation, status running, and null url and error fields; poll GET /v1/projects//publish/ until deployment finishes. Optionally set audience to choose who can open the published app; project reads report it as publish_audience. Omit audience to keep the current setting. Audience changes apply to the currently published version immediately, before the new deployment finishes. To change access settings without rebuilding, use PATCH /v1/projects//publish. To take the app offline, use DELETE /v1/projects//publish.

Authorizations

Lovable-API-Key

string

header

required

Lovable API key. Send its value in the Lovable-API-Key header.

Headers

Lovable-Version

string

Stable API version to serve, as a YYYY-MM-DD date. Omit for the oldest supported stable version, currently 2026-09-11.

Lovable-Beta

string

Comma-separated beta revision strings to enable on top of the stable version.

Path Parameters

project_id

string

required

Project ID.

Example:

"prj_01jw3k9m2xq8r5v0c7d4e6f2gh"

Body

application/json

audience

enum<string>

Who can open the published app; project reads report this value as publish_audience. A custom audience can include existing grants managed in the UI. Omit to keep the current setting.

Available options:

public,

workspace,

custom

Example:

"custom"

audience_targets

object[]

Groups who can open the app; allowed only with audience custom. Providing a list replaces all group and user grants and removes workspace-wide access; an empty list removes those grants. Existing organization access and email invitations managed in the UI are preserved. Omit to preserve saved targets across audience changes. Targets are inactive outside custom mode. Null is not accepted.

Maximum array length: 100

Show child attributes

Example:

[
  {
    "id": "grp_01jw3k9m2xq8r5v0c7d4e6f2gh",
    "type": "group"
  }
]

name

string

Slug for the managed published URL: acme-landing-page gives https://acme-landing-page.lovable.app. Custom domains and workspace branding can change the hostname.

Example:

"acme-landing-page"

Response

Deployment started. Poll GET /v1/projects/{project_id}/publish/{deployment_id} (the Location header) with the returned id until deployment finishes.

error_class

enum<string> | null

required

Where to address the failure; see the operation description for the action for each class. Null when no failure category is available. More values may be added; for unknown values, show error_message and contact support instead of automatically retrying.

Available options:

transient,

code,

configuration,

data,

integration,

policy,

internal,

null

Example:

"configuration"

error_message

string | null

required

Human-readable reason for a deployment failure; null unless the deployment failed.

Example:

"Missing environment variable VITE_API_URL"

string

required

Deployment ID.

Example:

"c3d4e5f6-a7b8-9012-cdef-345678901234"

status

enum<string>

required

Deployment progress. running means the deployment was accepted and has not reported completion. completed means the deployment succeeded and url is set. unknown means the deployment exists but its workflow state has no recognized public mapping; it confirms neither success nor failure. Poll again with backoff and a bounded timeout, then report an indeterminate result if it persists. Unknown or mismatched deployment IDs return HTTP 404. Clients must tolerate new values.

Available options:

running,

completed,

error,

unknown

Example:

"completed"

url

string | null

required

URL produced by this successful deployment; null until this deployment succeeds, even when an older version is published.

Example:

"https://acme-landing-page.lovable.app"
