Under the hood
Exactly what happens when a call ends in Synthflow
Every step, every API call, every field. This is how a Synthflow webhook becomes a Relevance AI record in under a second.
1
Call ends → Synthflow fires webhook
The moment an agent marks the call complete (or it auto-closes), Synthflow fires a POST webhook containing the full call payload.
/v2/calls
{
"call_id": "...",
"agent_name": "...",
"contact_phone": "...",
// + 5 more fields
}

"call_id": "...",

"contact_phone": "...",
// + 5 more fields
}
2
Payload validated + field-mapped
The integration layer receives the webhook, validates the signature (API Key (Bearer -- Integrations → API Keys in dashboard)), and maps each Synthflow field to the correct Relevance AI field — including disposition-to-stage logic.
disposition → deal_stage
recording_url → activity.recording
agent_id → owner_id
contact_phone → contact.phone
recording_url → activity.recording
agent_id → owner_id
contact_phone → contact.phone

Relevance AI API call fires
The integration calls the Relevance AI API (API Key (Authorization header)) to update the contact record, log the call activity, set the deal stage, and create a follow-up task if the disposition requires one.

The value is speed and scale. An AI agent can handle hundreds of simultaneous calls and qualify every lead in under two minutes. Without the integration, those qualification results sit inside Synthflow and never make it into Relevance AI where your team can act on them. With it, every AI call outcome becomes a structured Relevance AI record.

FAQ
Common questions about the
Common questions about the
Synthflow + Relevance AI integration.
Most builds are live in 5–10 business days from the discovery call. Simple setups with standard dispositions can be done in under a week. More complex builds — custom pipeline stages, multi-user routing, conditional logic — may take the full 10 days.
Yes. The integration fires within seconds of each call ending using webhooks from Synthflow and the Relevance AI API. Typical sync time is < 0.4s from call end to CRM record updated.
Disposition, recording URL, agent identity, call duration, notes, and any custom fields you specify — all mapped to the correct Relevance AI fields. You control the mapping during the field-mapping step.
Zapier works for simple triggers but gives no control over field-level mapping, disposition logic, or recording attachment. A direct API build is recommended for anything beyond basic one-way logging.
Synthflow fires an end-of-call webhook with the full conversation transcript, AI-generated summary, structured analysis, recording URL and cost. The integration captures this and maps it to Relevance AI fields.
That's the default case. We map your exact disposition codes to your exact Relevance AI pipeline stages — whatever you've named them. No preset templates to conform to.
The one-time setup fee (from $100) covers the build, end-to-end testing with real data, and 30 days of post-launch support. No per-call or per-record fees.
