Human Approval - HITL Platform

HITL.sh adds human approval and review workflows to AI agents and automations through loops and structured requests.

What agents can do

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.

You paste an API key from Human Approval - HITL Platform on a page Composio hosts, so the key never passes through Definable.

Keep the connection to yourself or share it with your workspace. Any action that writes or sends can wait for your approval.
