Overview
FormantAI helps teams configure AI phone agents, launch outbound calls, run CSV campaigns, ground conversations in business knowledge, call external tools, and sync outcomes through webhooks.
Make one outbound call, retrieve the result, and understand the full call lifecycle.
Configure prompts, voice, speech settings, tools, knowledge base access, phone routing, and webhooks.
Explore calls, batch campaigns, conversations, transcription, errors, and rate limits.
What you can build
Trigger personalized calls from your backend with dynamic parameters, idempotency, metadata, and trace IDs.
Upload a CSV, call many contacts with the same agent, monitor outcomes, and reconcile campaign results.
Attach approved FAQs, policies, pricing sheets, SOPs, and support playbooks to improve answer quality.
Let agents call your CRM, calendar, ticketing, payment, or internal APIs during live conversations.
Retrieve statuses, transcripts, recordings, trace IDs, and structured results after calls finish.
Send signed terminal call events to your backend, CRM, warehouse, or operations workflow.
