# Get OAuth connect URL

`GET /v1/connect/{platform}`

Initiate an OAuth connection flow. Returns an authUrl to redirect the user to.
Standard flow: Zernio hosts the selection UI, then redirects to your redirect_url. Headless mode (headless=true): user is redirected to your redirect_url with OAuth data for custom UI. Use the platform-specific selection endpoints to complete.

## Path parameters

- `platform` 'facebook' | 'instagram' | 'linkedin' | 'twitter' | 'tiktok' | 'youtube' | 'threads' | 'reddit' | 'pinterest' | 'bluesky' | 'googlebusiness' | 'telegram' | 'snapchat' | 'discord' | 'slack' | 'whatsapp', required

## Query parameters

- `profileId` string, required
- `redirect_url` string, uri
- `headless` boolean

## Response `200`

OAuth authorization URL to redirect user to

- object
  - `authUrl` string, uri — URL to redirect your user to for OAuth authorization
  - `state` string — State parameter for security (handled automatically)

## Other responses

- `400` — Missing/invalid parameters (e.g., invalid profileId format)
- `401` — Unauthorized
- `402` — Payment method or enterprise contract required. The authenticated account hit a billing gate before the connection could proceed. Three reasons: - `free_tier_exceeded`: the team has connected more accounts than the free tier allows. Add a payment method on the dashboard to continue (the user will be billed per additional connected account). - `twitter_passthrough`: connecting an X (Twitter) account requires a card on file from day one because X API calls incur real per-call pass-through costs. Applies to the 1st X account, not just the 3rd+. - `enterprise_required`: the team is on an enterprise contract with a negotiated connected-account cap and has reached it. Self-service teams have NO connection cap (the $1/account rate continues at any scale), so this reason can only fire for teams whose contract sets an explicit limit. `dashboard_url` deep-links to the enterprise contact page rather than the billing tab. The end-user already has a card on file; this gate is about contract terms, not card collection. SDK consumers should switch on `reason` to render the right prompt. For `free_tier_exceeded` and `twitter_passthrough`, redirect the end-user to `dashboard_url` to add a payment method via Zernio's hosted Stripe Setup Checkout. For `enterprise_required`, redirect to `dashboard_url` (the enterprise contact form) to adjust the contract's limit.
- `403` — No access to profile, or BYOK required for AppSumo Twitter
- `404` — Profile not found
