Use Writ
inside Zapier.
Give a Zap the one thing it can't reach on its own: a site with no API, behind your login.
Where Zapier alone hits a wall
Zapier connects thousands of apps that already expose an API. When the app or site you need doesn't have one, or the action lives behind a login with 2FA, there's no connector to pick, and a Zap can't drive a real browser to do it.
Writ becomes one step in your Zapier flow
Writ makes the no-API site behave like any other step in a Zap. Use a "Webhooks by Zapier" action (or a scheduled Zap) to POST to the Writ endpoint /v1/{slug}/{path} with your wt_ key; Writ runs the browser workflow on your account and returns JSON the next Zap step can use. Writ can also POST into a "Catch Hook" trigger to start a Zap when a watched page changes.
Connect Writ with Zapier
- 1
Publish the workflow in Writ
Record the login-gated action in Writ and publish it as a managed endpoint with a wt_ key.
- 2
Add a Webhooks by Zapier step
In your Zap, add a "Webhooks by Zapier → POST" action pointed at /v1/{slug}/{path}, with the wt_ key in the Authorization header.
- 3
Attach a persona for login/2FA
In Writ, attach a persona so login, TOTP, and mailbox-OTP 2FA are handled on your own account.
- 4
Map the response forward
Use Writ's JSON response in the following Zap steps, or start a Zap from Writ via a "Catch Hook" trigger on a page change.
The call Zapier makes
# Webhooks by Zapier → POST
URL: https://api.usewrit.app/v1/{slug}/{path}
Method: POST
Headers:
Authorization: Bearer wt_xxx
Content-Type: application/json
Data:
input.query: {{trigger.search_term}} A representative request. The endpoint is /v1/{slug}/{path}; authenticate with a wt_ key. API reference.
Zapier + Writ, side by side
An honest split of who does what. Writ never replaces your orchestrator; it reaches the part it can't reach alone.
| What you need | Zapier alone | Zapier + Writ |
|---|---|---|
| Apps that already have an API | Zapier's core strength: a huge connector catalog | ✓Stays native in Zapier, no Writ needed |
| A site with no connector at all | No connector to select; the site is unreachable from a Zap | ✓Writ turns it into a callable endpoint a Zap can POST to |
| Logged-in pages behind 2FA | Relies on each app's API/OAuth, not in-browser login | ✓Runs on your authorized session; TOTP + mailbox OTP handled |
| CAPTCHA on your own accounts | Not an in-browser capability | ✓Handled inside the Writ browser run |
| In-browser actions (fill, submit, buy) | Steps are app API actions, not page interactions | ✓30+ step types drive the real page |
| Start a Zap when a page changes | Triggers fire on app events, not arbitrary page changes | ✓Writ posts to a Catch Hook on a detected change |
