How Apollo works with Curviate

Apollo finds and enriches the right people, and Curviate reaches them on LinkedIn. Send people from Apollo to Curviate’s API to add contacts and start a Motion, and get replies back with a webhook.

What you can build

Three flows teams set up first. Each one takes a few minutes.

Apollo rows straight into a Motion

Enriched people go from Apollo to Curviate and get their first LinkedIn touch.

POST /v1/motions/…/contacts

Details your messages can use

Fields from Apollo, like a role or a recent event, travel along and fill your message templates.

POST /v1/contacts

Replies to your team

When someone replies on LinkedIn, your team hears about it in Slack.

Set up Apollo with Curviate

Everything runs on two things Curviate gives every account: signed webhooks out and a REST API in.

1
Copy your Curviate API key
In the Curviate dashboard, open Settings, then API & Webhooks, and copy your key.
# keep it in your tool's credentials, never in plain text
CURVIATE_API_KEY=cvt_live_••••3f9a
2
Send people from Apollo to Curviate
Use Apollo’s HTTP request or webhook action, or an automation tool, to call Curviate with each person’s LinkedIn URL. Extra fields travel along for your messages.
POST https://api.curviate.com/v1/contacts
{ "linkedin_url": "linkedin.com/in/lenaweber",
"list_name": "Apollo signals",
"extra": { "signal": "visited pricing" } }
3
Start the Motion
Add the new contacts to a Motion. They start within its schedule and each account’s limits.
# start your Motion for them
POST https://api.curviate.com/v1/motions/mot_…/contacts
{ "contact_ids": ["con_…"] }
4
Get replies back
Point a Curviate webhook at Apollo, your automation tool or Slack to hear about replies. Each webhook covers one source: messaging for replies, user for accepted invitations, motion for Motion outcomes, account_status for account alerts.
curl https://api.curviate.com/v1/webhooks \
  -H "Authorization: Bearer $CURVIATE_API_KEY" \
  -d '{
    "source": "messaging",
    "events": ["message.received"],
    "account_ids": ["acc_…"],
    "request_url": "https://your-endpoint.example.com/curviate"
  }'
5
Check the signature
Every delivery carries a Curviate-Signature header: an HMAC-SHA256 of the timestamp and the raw body, made with your webhook’s secret. Compare it before you act, and drop anything older than five minutes.
Curviate-Signature: t=1792230000,v1=5f2c9a…e81b

# expected = HMAC_SHA256(secret, t + "." + raw_body)

API reference

Questions about Curviate x Apollo

What does Curviate need from Apollo?

A LinkedIn profile URL per person. Names, company and any extra fields are optional and can be used in your messages.

Will someone be contacted twice?

No. Curviate recognises a person by their LinkedIn profile, so sending them again updates the contact, and Motions can skip people who are already in another Motion.

How fast does a new person start?

Right away, within the Motion’s schedule and each account’s limits.
