TOOLS

Supported Tools

Every Human Approval - HITL Platform action and event your agent gets out of the box.

Cancel Approval Request

Irreversibly cancel a pending approval request so reviewers can no longer complete it.

Create Approval Request

Create and broadcast one human approval request to active members of an owned loop, consuming one provider request allowance.

Create Loop

Create an approval loop and return its loop ID and human invitation links; the connected account is added as an active member.

Delete Loop

Permanently delete an owned loop and all of its memberships, approval requests, responses, feedback, and analytics.

Get Account Status

Return the connected HITL account identity, status, permissions, and provider-reported request allowance before creating an approval request.

Get Approval Request

Get the current status, configuration, and human response for one approval request; use for deliberate polling after creation.

List Approval Requests

Return approval requests created by the connected API key, optionally restricted to one loop; pagination controls are omitted because the live API currently ignores them.

List Loop Members

Return a loop's active and pending human reviewers so an agent can verify readiness before broadcasting an approval request.

List Loops

Return all approval loops owned by the connected account, including embedded members and membership counts.

Update Loop

Update one or more display fields of an owned approval loop without changing its members or requests.

FAQ

Frequently asked questions

Yes, Human Approval - HITL Platform requires you to configure your own API key. Once set up, Composio handles secure credential storage and API request handling for you.

Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.

Yes. Composio is SOC 2 Type II compliant and is built to keep your Human Approval - HITL Platform connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.

Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.

Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.

Create the key in your Human Approval - HITL Platform account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the Human Approval - HITL Platform actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside Human Approval - HITL Platform at any time.

When you connect a Human Approval - HITL Platform account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Human Approval - HITL Platform as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.

Whatever the credentials you connect allow inside Human Approval - HITL Platform. If Human Approval - HITL Platform lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside Human Approval - HITL Platform at any time.

Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each Human Approval - HITL Platform connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.

The connection stops working the moment Human Approval - HITL Platform rejects the old key. Create a new key in Human Approval - HITL Platform and reconnect the account from the Composio dashboard or by asking your agent to reconnect Human Approval - HITL Platform. Nothing else changes.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal Human Approval - HITL Platform use. Paid plans add higher limits and team features. Your Human Approval - HITL Platform plan and its API limits still apply as usual.

Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple Human Approval - HITL Platform accounts).

With Composio, you connect Human Approval - HITL Platform once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
