Authentication & Accounts

This article walks through the two things you need before your first API call: obtaining your Curviate API key and connecting a LinkedIn account.

Step 1 — Obtain your API key

Your Curviate workspace API key is ready as soon as you sign up. It lives in the key chip at the top-right of the dashboard top bar. The chip shows the key prefix (for example cvt_live_…); click the copy icon on the chip to copy the full key to your clipboard. The key is a tenant-scoped secret that works across the REST API, CLI, and MCP server, and you only need one. If you have revoked your key, the chip shows a Generate API key control to mint a replacement; that full key is revealed once, so copy it right away.

Step 2 — Understand the key format and keep it safe

PropertyValue
Live formatcvt_live_… (24-character suffix)
Test formatcvt_test_… (24-character suffix)
ScopeTenant workspace — all accounts and resources
TTLNon-expiring until rotated
RotationKey chip → menu → Refresh token
StorageServer-side environment variable only

Security

  • Store the key in an environment variable (CURVIATE_API_KEY). Never put it in client-side code or version control.
  • Rotate immediately on suspected exposure via the key chip's menu → Refresh token (the replacement is shown once). To disable a key entirely, use Revoke key.

Step 3 — Connect a LinkedIn account

Before your API calls can act on LinkedIn, you need to connect a LinkedIn account in the Curviate dashboard.

  1. In the dashboard, navigate to Accounts (/accounts).
  2. Click Connect account. If you have no seats, the modal prompts you to purchase a seat first.
  3. The connect modal offers two authentication methods:
    • Credentials (recommended) — enter your LinkedIn email and password. Credentials are encrypted at rest and never logged.
    • Cookie — paste the li_at value from your browser's LinkedIn cookies. The modal includes an inline "How to find my cookies?" guide.
  4. Select your preferred method, fill in the form, and click Connect.
  5. If LinkedIn issues a verification challenge, the dashboard walks you through it — entering a one-time code (from email, SMS, an authenticator app, or WhatsApp), choosing between a code and an in-app approval, approving the sign-in in the LinkedIn mobile app, or picking a Recruiter / Sales Navigator seat. A mobile-app approval is time-limited (a few minutes); if it expires before you approve, the dashboard explains how to retry.
  6. If that LinkedIn identity is already connected to your workspace, the dashboard offers to reconnect the existing account rather than creating a duplicate — one LinkedIn account maps to one connection per workspace.
  7. On success, your account appears in the Accounts list with status active and a copy-able acc_… account ID.

Account ID — The account_id (format acc_…) identifies your connected LinkedIn account in every API call, CLI command, and SDK method. You can copy it from the Accounts table at any time.

Connecting accounts programmatically

You can connect accounts from the API instead of the dashboard — for example, to onboard your own customers. POST /v1/auth/intent is the single connect path: you supply the LinkedIn credentials or cookie, and the same endpoint handles both a brand-new connection and re-authenticating an existing one in place. LinkedIn often responds with a verification challenge, so the flow can take more than one call:

  1. POST /v1/auth/intent with either auth_method: "credentials" (email + password) or auth_method: "cookie" (li_at). Cookie auth also requires a top-level user_agent — the exact browser User-Agent the cookie was captured with. Omit account_id to connect a new account into the given seat_id; include account_id in the body to re-authenticate an existing account in place — the same endpoint handles both.

  2. A 201 (new) or 200 (reconnect) means the account connected immediately. A 202 means a challenge is required — the body carries an account_id, a challenge_type, and an expires_at:

    {
      "object": "checkpoint",
      "status": "checkpoint_required",
      "account_id": "acc_...",
      "challenge_type": "two_factor_app",
      "expires_at": "2026-06-08T10:10:00Z"
    }
  3. Resolve the challenge on the same account. For a code-based challenge, submit the code to POST /v1/auth/checkpoint/solve with { "account_id": "acc_...", "code": "123456" }; re-request the notification with POST /v1/auth/checkpoint/request (same body shape) if the user never received it. For a mobile_app_approval challenge, the user approves the sign-in in the LinkedIn app — poll POST /v1/auth/checkpoint/poll with { "account_id": "acc_..." } until it returns the connected account, or until expires_at passes and it reports status: "expired". You can also read the connect's current status at any time with GET /v1/auth/sessions/{session_id}, passing the connect's account_id (the acc_… id) as session_id.

  4. A resolved challenge returns the connected account. If it turns out to re-adopt an identity your workspace already holds, the account is returned with "recovered": true.

If the identity is already connected, POST /v1/auth/intent (new-connect branch) returns 409 ACCOUNT_ALREADY_LINKED — pass that identity's account_id in the body on a follow-up POST /v1/auth/intent call to re-authenticate it in place instead of creating a duplicate. When your workspace already owns that account, the error names your own account_id so you can reconnect it directly.

Every step above has a CLI equivalent under curviate account — see the CLI account reference. For the full request and response shapes, see the API reference.

Privacy Policy

Redmer Holding GmbHLast updated July 25, 2026

Who we are

Curviate is operated by Redmer Holding GmbH ("Curviate", "we", "us"), a German GmbH registered at Amtsgericht Bonn, HRB 29957, registered address Hostertstraße 16, 53332 Bornheim, Germany. Full company details are on our Imprint. We haven't appointed a statutory Data Protection Officer, since our processing doesn't reach the scale or sensitivity that requires one. Privacy questions go to privacy@curviate.com.

The two roles we play

When you create an account and use Curviate, we process your own data (identity, billing, API keys, connector authorizations). For that data, we are the controller.

When you use Curviate to act on your own connected LinkedIn account, viewing profiles, sending messages, managing engagement, that content and those contacts belong to that account and its people. You are the controller of that data; we are the processor, acting only on your instructions, under the Data Processing Agreement between us. If one of your contacts has a question about being reached through Curviate, you're who they should contact first; email privacy@curviate.com if you need help routing it.

What we collect, and why

DataWhy
Account identity (name, email, sign-in method)Create and secure your account
Your LinkedIn credentialsOperate the actions you request
LinkedIn content returned by an API callFulfil that specific request, nothing more
API keys and connector (OAuth) authorizationsAuthenticate your API, CLI, MCP, or SDK requests
Billing detailsCharge you correctly and meet our tax obligations
Usage and security logsKeep the service reliable and abuse-free
Support messagesRespond to you
Website analytics, only if you opt inUnderstand how the site is used

We rely on our contract with you, our legitimate interest in running and securing the service, our legal obligations (tax law, for example), and, for analytics, your consent. We never sell your data or use it to train models.

Where it's processed, and who else touches it

Our infrastructure runs in the EU. Hosting: Railway. Database and auth: Supabase, Ireland. Email: Resend. Payments: Stripe. Network security: a DDoS-protection provider sits in front of our app and never sees or stores request content. LinkedIn connectivity: a third-party infrastructure provider that lets us execute LinkedIn actions on your behalf. Error tracking: Sentry, Frankfurt. Product analytics: PostHog, Frankfurt. Uptime monitoring: Better Stack.

We give the current, named list of every provider above, plus our Data Processing Agreement, to any customer who asks: security@curviate.com.

Outside the EU

All customer LinkedIn data, account data, and telemetry are processed and stored exclusively in EU regions of our sub-processors. A few providers we rely on (Stripe and Sentry, for example) are headquartered outside the EU/EEA; where that applies, it's covered by their own GDPR safeguards, typically the EU Standard Contractual Clauses.

How long we keep it

DataRetention
Account and workspace dataWhile your account is active
Closed accountRecoverable for 7 days, then deleted on day 8
LinkedIn credentialsUntil you disconnect that account
LinkedIn contentNot stored; any transient cache clears within 1 hour, never indexed, never used for training
API keysUntil you revoke or rotate them
Connector (OAuth) authorizationsAccess token ~1 hour; refresh token up to ~12 months, or until you revoke it, whichever comes first
Billing recordsAs required by German tax law, currently up to 10 years
LogsA short operational window; metadata only, never message content

The 12-month figure above is a server-side credential for a connected AI agent or app. It is not a cookie and doesn't touch your browser session; see Cookies below for that. You can see and revoke every connector from Authorized applications in your dashboard at any time.

Cookies

We keep cookies to a minimum, and ask before anything beyond the essentials runs.

Strictly necessary, no consent needed:

NamePurposeExpiry
cc_cookieRemembers your cookie choice12 months
curviate-themeRemembers light/dark mode (local storage, not a cookie)Persistent
sb-*-auth-tokenKeeps you signed inWhile active; cleared on sign-out

Analytics, only if you accept:

NamePurposeExpiry
_gaGoogle Analytics: distinguishes visitors2 years
_gidGoogle Analytics: distinguishes visitors24 hours
_ga_<container id>Google Analytics: persists session state2 years

No advertising cookies, ever. Accept and reject are equally easy, and you can change your mind any time via Cookie Preferences in the footer; we won't ask again for 12 months unless something material changes. Our LinkedIn connect flow and OAuth authorization screen never set anything beyond the essentials, so no banner appears there.

Connecting an AI agent or app

Curviate is built for AI agents and automated clients as much as for people. If you connect an app like Claude, or your own code, via an API key or an OAuth connector, it can act on your workspace within the access you gave it. What it does with anything it receives back, including what it sends to its own AI model, is between you and that provider; review its practices before connecting it. Review and revoke any connection any time from your dashboard.

Your rights

You can access, correct, delete, restrict, or object to your data, port it elsewhere, and withdraw consent at any time: email privacy@curviate.com. Closing your account starts the 7-day recoverable window above. We don't make automated decisions about you that have a legal or similarly significant effect. You can also complain to a supervisory authority; ours is the Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen (LDI NRW), www.ldi.nrw.de, though you're free to complain to the one in your own country instead.

Keeping it secure

Credentials are encrypted and never logged, returned, or shared. LinkedIn actions run through native, humanized flows; full detail is on our Security & Compliance page. If a breach puts your rights at risk, we'll notify the authorities and you, as GDPR requires. Curviate isn't directed at, or offered to, anyone under 16.

Changes

We'll update this page when our practices change, and reset the cookie prompt if the change is material.
