By default they come back on the next monthly date; pass `forced: true` to take them back now. Billing on the source order is unchanged. A live reservation that used `forwarding_url` requires the pool recycle forwarding URL configured by Peeker during production setup. Sandbox supplies a local recycle target automatically. ## OpenAPI ````yaml /openapi.yaml post /pool/release openapi: 3.1.0 info: title: Peeker Partner API version: 1.0.0 description: > White-label Peeker's email infrastructure: Google Workspace and Microsoft 365 inboxes, deliverability monitoring, and self-healing domain swaps, from your own app. Create a provider workspace target, order licenses with imported or Peeker-managed domains, and Peeker's backend handles provisioning, DNS, forwarding, and lifecycle webhooks. Create a provider workspace target with `POST /workspaces`, then send its `wrk_...` ID to `POST /orders`. For Smartlead, create one main workspace, then add `client_id` to an order only when it should go to a client workspace. Omit it to order into the main workspace. ## Read first - **[Authentication](/authentication)**: bearer keys, live vs sandbox, request IDs. - **[Rate limits](/rate-limits)**: 600/min per key, 429 backoff. - **[Webhooks](/webhooks)**: signed events and delivery rules. - **[Async jobs](/concepts/async-jobs)**: what to poll vs subscribe to. - **[Best practices](/best-practices)**: errors, paging, idempotency. ## Concepts - **[Orders](/concepts/orders)**: statuses, sizing, pending actions, cancel. - **[Domains](/concepts/domains)**: inventory, `usable_for`, import, forwarding. - **[Bundles](/concepts/bundles)**: saved templates and capacity. - **[Swaps](/concepts/swaps)**: standard vs premium, renames. ## Workflow guides - **[Provider ordering](/guides/provider-ordering)** — create a provider workspace target and order through it. - **[Buying domains & ordering](/guides/buying-domains)** — the default flow: bundle, availability, order, webhooks. - **[Importing domains](/guides/importing-domains)** — bring in existing customer domains. - **[Forwarding](/guides/forwarding)** — point a domain at a marketing site. - **[How to implement domain swaps](/guides/domain-swaps)** — standard vs premium swaps. - **[Renaming inbox senders](/guides/user-name-swaps)** — change mailbox personas on a warm domain. ## Public ID prefixes | Prefix | Resource | | --- | --- | | `cus_` | Customer tracking record | | `wrk_` | Provider workspace | | `bun_` | Bundle | | `ord_` | Order | | `dom_` | Domain | | `pcl_` | Pool reservation | | `prp_` | Pool replacement | | `prl_` | Pool release | | `imp_` | Domain import job | | `fwj_` | Domain forwarding job | | `brj_` | Burned-domain replacement job | | `swp_` | Domain swap | | `act_` | Pending action | | `evt_` | Webhook event | servers: - url: https://api.peeker.ai/partner/v1 description: >- Same base URL for live and sandbox.

Returns environment (live or sandbox), permission preset, and the partner profile. See [Authentication](/authentication). - name: Provider workspaces x-group: Provider workspaces description: | A provider workspace is one reusable provider connection. Create it once, keep the returned `wrk_...` ID, and use it in orders and pool attach. Optional customer tracking stays on the target. Provider credentials stay internal and are never echoed. EmailBison requires a workspace API-user key. Super-admin keys are rejected. Instantly and Smartlead connections require `api_key`. Smartlead workspace creation takes a main API key and a label. Do not send `client_id` or customer data. Its login email and password are optional, but must be sent together. Google orders do not need the pair, and orders never accept it. Smartlead Microsoft orders and pool attach still use the workspace-saved pair. Add `client_id` to the order destination when the order belongs to a client workspace; omit it for the main workspace. PlusVibe setup requires `api_key`, remote `workspace_id`, and its login email/password pair so orders and pool attach work immediately. Instantly login credentials belong on an order destination. - name: Bundles x-group: Bundles description: | Saved order template sized by monthly sending volume (`bun_…`). Pass `bundle_id` on an order instead of custom license counts. Lifecycle: [How bundles work](/concepts/bundles). - name: Domains x-group: Domains description: > Sending domains in your partner account (`dom_…`). Same ID whether or not the domain is on an order. **Status values** | Value | What it means | | --- | --- | | `available` | The domain is in inventory but not on an order yet. | | `in_progress` | We're setting it up. | | `active` | Live and warming or healthy. | | `failed` | Something broke that we can't fix automatically. | | `action_required` | We need your help (e.g. update nameservers). | **Inventory vs connected** - `category=inventory` — yours but not on any order. Inventory rows don't include `provider`. - `category=connected` — on an active order. The row carries the link fields `provider`, `customer_id`, `order_id`, `usable_for`, and `forwarding_url`. **`usable_for` matrix** When you check a domain's availability: | Who's on the domain | `usable_for` | | --- | --- | | Nobody, or just Google | `["google", "microsoft"]` | | Microsoft (or both) | `["google"]` | | Premium / invalid / errored | not orderable; `available: false` with a `reason` | **Imports and forwarding are jobs** Both **import** and **forwarding** are async jobs. Posting to those endpoints starts the job and gives you back a row with `status: "in_progress"`. Poll the job's GET endpoint to see when it finishes: - Import jobs: prefix `imp_…`. Includes the `nameserver_groups` your customer needs to set at their registrar. - Forwarding jobs: prefix `fwj_…`. Already-correct domains are returned in `completed` with newly updated domains. - name: Domain pool x-group: Domain pool description: | Assign an exact quantity from pre-warmed Google inventory. Each domain needs at least one active Google inbox on a paid Google order (commonly two), complete provider mailbox identity, and no explicit burned provider result. Attach is all-or-nothing: full quantity or `insufficient_inventory` with no pool change. Attach and release are async. Poll the resource or subscribe to `pool.*` webhooks. Guide: [Pre-warmed pool](/guides/pre-warmed-pool). - name: Orders x-group: Orders description: | One purchase of domains plus Google and/or Microsoft licenses for one customer (`ord_…`). Use a saved `bundle_id` **or** custom license counts, never both. Requires `Idempotency-Key`. Lifecycle: [How orders work](/concepts/orders). - name: Domain swaps x-group: Domain swaps description: | Replace a domain inside an existing order without losing the order (`swp_…`). For persona-only changes use `POST /swaps/user_names`.

Register the URL and secret in the [Partner portal](https://app.peeker.ai/partner/webhooks). Event IDs look like `evt_01HZX`. Delivery is at least once (up to 5 attempts).
