What is Cargo?

Cargo is go-to-market infrastructure that coding agents operate, with a shared data model, connectors, hosted execution and run traces. Technical revenue teams and GTM engineers use it.

How Cargo works with Curviate

Curviate sends LinkedIn events to the Cargo HTTP › Listen webhook trigger as they happen, and Cargo calls the Curviate API to act on LinkedIn: add people to a Motion, send a message or read a company page. Signed webhooks out, a REST API in.

What you can build

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

Every reply, straight to your team

A new LinkedIn reply posts the message and the sender’s profile to a Slack channel.

message.received

Form leads into a Motion

Someone fills in your Typeform, and Cargo adds them to the right Motion within seconds.

POST /v1/motions/…/contacts

Accepted invites in your CRM

When an invitation is accepted, Cargo creates or updates the contact in HubSpot.

connection.accepted

Set up Cargo 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
Start with the HTTP › Listen webhook trigger
Create a new flow in Cargo, start it with the HTTP › Listen webhook trigger and copy the URL it gives you.
# the URL your HTTP › Listen webhook trigger gives you
https://your-cargo-webhook-url
3
Send Curviate events to it
Create a webhook in Curviate for the events you need, then send a test event so Cargo can read the fields. You can do the same in the dashboard under Settings, then API & Webhooks. 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-cargo-webhook-url"
  }'
4
Call Curviate from Cargo
Add the HTTP › Call action with the headers Authorization: Bearer plus your key and Content-Type: application/json, and call any Curviate action. This one adds a person and starts a Motion.
# add the person as a contact
POST https://api.curviate.com/v1/contacts
{ "linkedin_url": "linkedin.com/in/lenaweber", "first_name": "Lena" }

# start your Motion for them
POST https://api.curviate.com/v1/motions/mot_…/contacts
{ "contact_ids": ["con_…"] }
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)

Questions about Curviate x Cargo

Which LinkedIn events can start a Cargo flow?

Messages, accepted invitations, published posts, account status changes and every step of a Motion, from a contact starting it to a reply that ends it.

Can Cargo act on LinkedIn too?

Yes. Every Curviate action is a plain HTTPS call, so Cargo can search, message, invite or start a Motion, inside the limits you set for each account.

Do I need to write code?

No. A webhook trigger and an HTTP request are all it takes, and Cargo maps the fields for you.
