Under the `human` policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after. do domain_au.portfolios.delete confirm_policy: **human** Delete Portfolio? **intent:** the user asked me to delete Portfolio run suspended · waiting for a named person · key _domain-au-agent_ cannot confirm itself In the console, or from an emailed signed link. a key for this connector ``` account { op: "keys.create", name: "domain-au-agent", allowed_actions: ["domain_au.*"], cap_calls: 2000, confirm_policy: "human_for_writes", approval_rules: [ { match: "domain_au.portfolios.delete", approver: "lead@example.com" }, { match: "domain_au.portfolios.remove_properties", approver: "lead@example.com" }, { match: "domain_au.webhook_subscriptions.delete", approver: "lead@example.com" } ] } ``` Illustrative.

Plus your sandbox and your scopes. The free call account { op: "connections.requirements", service: "domain_au" } lists exactly what to paste. **Can an AI agent delete or change things in Domain?** Only if its key allows it, and only with an explicit confirmation. 6 Domain actions are destructive, including delete Portfolio, remove Properties from Portfolio and delete a single subscription. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it. **Will an AI agent use up my Domain API limit?** actionlake paces every call to the limits in the Domain service file: 1,000 calls a minute per connection. Repeated reads are answered from cache (87 Domain actions can be), which never reaches Domain. **What does a Domain action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (112 Domain actions page). Cache hits, searches, dry runs and calls Domain refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000. **Which Domain API does it cover?** The Domain Public API v1/v2 (OpenAPI 3.0.4) at api.domain.com.au, under your sandbox. It is built from Domain's documentation as read on 23 October 2026. 112 actions in 30 areas, each one in the signed service file (version 1.0.0). **Can I combine Domain with my other systems?** Yes. ask joins Domain to ConnectWise PSA or NetSuite on the same customer and returns the answer rather than every row. Domain maps crm.company, which 227 other connectors also map. **Does actionlake keep my Domain data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Domain credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like Domain Shares the most action names with - [Cloudbeds 3](https://actionlake.com/connectors/cloudbeds) - [Guesty 2](https://actionlake.com/connectors/guesty) - [iManage Work 1](https://actionlake.com/connectors/imanage-work) Joins with, on shared entities - [HubSpot CRM 3](https://actionlake.com/connectors/hubspot-crm) - [Salesforce Sales Cloud 3](https://actionlake.com/connectors/salesforce-sales-cloud) - [Bitrix24 3](https://actionlake.com/connectors/bitrix24) - [Simpro 3](https://actionlake.com/connectors/simpro) - [Acumatica Cloud ERP 3](https://actionlake.com/connectors/acumatica-cloud-erp) - [Odoo 3](https://actionlake.com/connectors/odoo) Browse - [All Industry connectors](https://actionlake.com/connectors/category/industry) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
