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 Apollo.io 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": "...",
"agent_name": "...",
"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 Apollo.io 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

Apollo.io API call fires
The integration calls the Apollo.io API (API Key (x-api-key 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.

POST /v1/contacts

Without the integration, AI call results sit inside Synthflow and never reach Apollo.io where your team can act on them. With it, every AI call outcome becomes a structured Apollo.io record — contact updated, pipeline stage set, activity logged with transcript attached.

FAQ
Common questions about the
Common questions about the
Synthflow + Apollo.io 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 Apollo.io 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 Apollo.io 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 Apollo.io fields.
That's the default case. We map your exact disposition codes to your exact Apollo.io 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.
