This catalog maps all 68 operations in the canonical contract checked on September 9, 2026. Choose a workflow below, then open the operation’s reference or Markdown export. Consult the live OpenAPI document for the current catalog, complete schemas, descriptions, and MCP annotations. Every operation uses POST https://gateway.firsttouch.ai/api/public/tools/<tool_name> with an X-API-Key header and a JSON object body. Keep underscores in the tool name; the hyphenated documentation URL is not the API path. Start with Agent Start Here and the quickstart. Before writes or charged work, read the specific operation’s prerequisites, permission requirements, costs, and side effects. A read-only annotation does not imply an operation is free. See execution and recovery before retrying an ambiguous result.

Account, Team, And Guidance

Start with the active identity and capabilities; use the relevant guide before workflow operations.

Contacts, Discovery, And Enrichment

Use existing-data lookup before charged enrichment. Discovery and enrichment have credit rules; load the contact_discovery guide before discovery or background import.

Audiences And HubSpot Lists

Use Audiences for lists or groups of contacts. Review the audience_management guide and the operation-specific source requirements.

Flow Plans

Use reusable Flow Plans for multi-contact workflows. Load flow_plan_creation, inspect validation, and review publication and enrollment settings before activation.

Enrollments And Single-Contact Actions

Load enrollment_management for regular enrollments or dynamic_actions for a one-contact action. Dynamic Actions require identity, enrollment, and sender preflight; retain the returned write receipt.

Tasks, Queues, And Diagnostics

Preview approval tasks before authorized completion. Inspect enrollments and tasks as well as queues when diagnosing work that has not run.

LinkedIn Inbox And Connections

Read the exact conversation before replying. send_linkedin_unibox_message requires explicitly requested or approved text and must never be retried automatically.

Social Engagement

Inspect the existing linked Social Engagement flow. Adding or activating monitored profiles requires the documented role and paid, non-trial access.

Metrics, Credits, And Billing

Inspect current costs and credit context before charged work. Access to team-wide metrics and billing data depends on the caller.
