# Add a bucket custom domain

POST https://api.ibee.ai/v1/object-storage/buckets/{bucket_name}/custom-domains
Content-Type: application/json

Adds a custom hostname that serves the bucket. Create the CNAME record shown in `cname_target`, then check `status` on the list. Requires scope: object-storage.write.

```
# Example request with curl (set IBEE_API_TOKEN to a platform API token and WORKSPACE_ID to the workspace first).
# BUCKET_NAME: Logical bucket name
curl -X POST "https://api.ibee.ai/v1/object-storage/buckets/$BUCKET_NAME/custom-domains?workspace_id=$WORKSPACE_ID" \
  -H "Authorization: Bearer $IBEE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"domain": "<domain>"}'
```

Reference: https://ibee.ai/docs/api-reference/object-storage/add-bucket-custom-domain

## Authentication

- `Authorization` header (bearer token, required) — IBEE platform API token. Production tokens start with `ibee_prod_key_`; development tokens start with `ibee_dev_key_`. Use a token only with its matching gateway environment.

## Servers

- `https://api.ibee.ai/v1` (Production, default)
- `https://api.ibee.co.in/v1` (Development)

## Request

### Path parameters

- `bucket_name` (string, required) — Logical bucket name.

### Query parameters

- `workspace_id` (string, required) — The positive numeric workspace ID to scope this request to. Zero, negative, and non-numeric values are rejected.

### Body (application/json)

This endpoint expects an AddBucketCustomDomainRequest.

- `domain` (string, required) — Hostname to serve the bucket from, for example `assets.example.com`.

## Response

### 201

Add a bucket custom domain succeeded.

- `domain` (string, required)
- `status` (string, required) — Current state of the hostname (DNS check and TLS).
- `cname_target` (string, optional) — Hostname the CNAME record must point at.
- `created_at` (datetime, optional, nullable)

## Errors

### 400 Bad Request Error

The request is invalid. From the gateway: `workspace_id_required` or `invalid_workspace_id`; on billable creates also `invalid_json_body` and selection codes such as `plan_id_required`, `invalid_site_id`, `compute_billing_term_required` or `invalid_block_storage_selection`. Otherwise the product service's `detail`.

- `error` (string, optional, nullable) — Machine-readable code from the gateway's authorization step, for example `invalid_api_key`, `insufficient_scope`, `organization_restricted`, `organization_suspended`, `verification_required`, `product_not_enabled` or `billing_denied`. The response descriptions list the codes for each status.
- `required_scope` (string, optional, nullable) — The scope the token lacks, with `insufficient_scope`.
- `billing_reason` (string, optional, nullable) — Billing's reason with `billing_denied`, passed through unchanged: for example `insufficient_balance`, `credit_limit_exceeded`, `initial_topup_required`, `resource_limit_reached` or `resource_usage_unavailable`.
- `billing_sku_code` (string, optional, nullable) — The SKU the billing admission checked, when there was one.
- `billing_evaluated_at` (string, optional, nullable) — When Billing made the decision, as Billing returned it.
- `admission_context_id` (string, optional, nullable) — Billing admission context for this request, derived from the token, workspace, route and `X-Idempotency-Key`, so a retry with the same key gets the same id.
- `detail` (ErrorDetail, optional) — Error detail from the product service.

### 401 Unauthorized Error

The API token is missing, malformed or unknown (`invalid_api_key`).

- `error` (string, optional, nullable) — Machine-readable code from the gateway's authorization step, for example `invalid_api_key`, `insufficient_scope`, `organization_restricted`, `organization_suspended`, `verification_required`, `product_not_enabled` or `billing_denied`. The response descriptions list the codes for each status.
- `required_scope` (string, optional, nullable) — The scope the token lacks, with `insufficient_scope`.
- `billing_reason` (string, optional, nullable) — Billing's reason with `billing_denied`, passed through unchanged: for example `insufficient_balance`, `credit_limit_exceeded`, `initial_topup_required`, `resource_limit_reached` or `resource_usage_unavailable`.
- `billing_sku_code` (string, optional, nullable) — The SKU the billing admission checked, when there was one.
- `billing_evaluated_at` (string, optional, nullable) — When Billing made the decision, as Billing returned it.
- `admission_context_id` (string, optional, nullable) — Billing admission context for this request, derived from the token, workspace, route and `X-Idempotency-Key`, so a retry with the same key gets the same id.
- `detail` (ErrorDetail, optional) — Error detail from the product service.

### 403 Forbidden Error

The token may not make this call. Gateway codes: `insufficient_scope` (with `required_scope`), `key_revoked`, `key_disabled`, `key_inactive`, `key_expired`, `unknown_route`, `workspace_not_allowed`, `principal_inactive`, `principal_not_member` and `principal_permission_denied`. `product_not_enabled` when the product is not enabled for the organization (IBEE turns some products on per organization; ask support for access). On writes, also `organization_restricted` (an admin restricted the organization) and `verification_required` (the token's user has not completed identity verification). A product service may also refuse with `detail`.

- `error` (string, optional, nullable) — Machine-readable code from the gateway's authorization step, for example `invalid_api_key`, `insufficient_scope`, `organization_restricted`, `organization_suspended`, `verification_required`, `product_not_enabled` or `billing_denied`. The response descriptions list the codes for each status.
- `required_scope` (string, optional, nullable) — The scope the token lacks, with `insufficient_scope`.
- `billing_reason` (string, optional, nullable) — Billing's reason with `billing_denied`, passed through unchanged: for example `insufficient_balance`, `credit_limit_exceeded`, `initial_topup_required`, `resource_limit_reached` or `resource_usage_unavailable`.
- `billing_sku_code` (string, optional, nullable) — The SKU the billing admission checked, when there was one.

- `admission_context_id` (string, optional, nullable) — Billing admission context for this request, derived from the token, workspace, route and `X-Idempotency-Key`, so a retry with the same key gets the same id.
- `detail` (ErrorDetail, optional) — Error detail from the product service.

### 404 Not Found Error

The requested resource was not found.

- `error` (string, optional, nullable) — Machine-readable code from the gateway's authorization step, for example `invalid_api_key`, `insufficient_scope`, `organization_restricted`, `organization_suspended`, `verification_required`, `product_not_enabled` or `billing_denied`. The response descriptions list the codes for each status.
- `required_scope` (string, optional, nullable) — The scope the token lacks, with `insufficient_scope`.
- `billing_reason` (string, optional, nullable) — Billing's reason with `billing_denied`, passed through unchanged: for example `insufficient_balance`, `credit_limit_exceeded`, `initial_topup_required`, `resource_limit_reached` or `resource_usage_unavailable`.
- `billing_sku_code` (string, optional, nullable) — The SKU the billing admission checked, when there was one.

- `error` (string, optional, nullable) — Machine-readable code from the gateway's authorization step, for example `invalid_api_key`, `insufficient_scope`, `organization_restricted`, `organization_suspended`, `verification_required`, `product_not_enabled` or `billing_denied`. The response descriptions list the codes for each status.
- `required_scope` (string, optional, nullable) — The scope the token lacks, with `insufficient_scope`.

- `detail` (ErrorDetail, optional) — Error detail from the product service.

### 503 Service Unavailable Error

A service the request depends on did not answer. Gateway codes: `workspace_verification_unavailable`, `principal_verification_unavailable`, `principal_authorization_unavailable` and `product_check_unavailable` (whether the organization has the product could not be checked; retry later); on billable creates also `billing_admission_timeout`, `billing_admission_unavailable`, `billing_admission_disabled`, `billing_admission_not_configured` and the catalog codes `compute_catalog_unavailable`, `compute_catalog_not_configured`, `product_catalog_timeout`, `product_catalog_unavailable`, `product_catalog_not_configured` and `unsupported_product_quote`. Otherwise the product service's `detail`.
