+# Setting up Zapier Integration
+
+If you run it on localhost, check out the [additional information](https://github.com/CarinaWolli/cal.com/edit/feat/zapier-app/packages/app-store/zapierother/README.md#localhost) below.
+
+1. Create [Zapier Account](https://zapier.com/sign-up?next=https%3A%2F%2Fdeveloper.zapier.com%2F)
+2. If not redirected to developer account, go to: [Zapier Developer Account](https://developer.zapier.com)
+3. Click **Start a Zapier Integration**
+4. Create Integration
+    - Name: Cal.com
+    - Description: Cal.com is a scheduling infrastructure for absolutely everyone.
+    - Intended Audience: Private
+    - Role: choose whatever is appropriate
+    - Category: Calendar
+
+## Authentication
+
+1. Go to Authentication, choose Api key and click save
+2. Click Add Fields
+    - Key: apiKey
+    - Check the box ‘is this field required?’
+3. Configure a Test
+    - Test: GET ```<baseUrl>```/api/integrations/zapierother/listBookings
+    - URL Params
+        - apiKey: {{bundle.authData.apiKey}}
+4. Test your authentication —> First you have to install Zapier in the Cal.com App Store and generate an API key, use this API key to test your authentication (only zapier Api key works)
+  
+## Triggers
+
+Booking created, Booking rescheduled, Booking cancelled
+  
+### Booking created
+
+1. Settings
+    - Key: booking_created
+    - Name: Booking created
+    - Noun: Booking
+    - Description: Triggers when a new booking is created
+2. API Configuration (apiKey is set automatically, leave it like it is):
+    - Trigger Type: REST Hook
+    - Subscribe: POST ```<baseUrl>```/api/integrations/zapierother/addSubscription
+        - Request Body
+            - subscriberUrl: {{bundle.targetUrl}}
+            - triggerEvent: BOOKING_CREATED
+    - Unsubscribe: DELETE ```<baseUrl>```/api/integrations/zapierother/deleteSubscription
+        - URL Params (in addition to apiKey)
+            - id: {{bundle.subscribeData.id}}
+    - PerformList: GET ```<baseUrl>```/api/integrations/zapierother/listBookings
+3. Test your API request
+
+Create the other two triggers (booking rescheduled, booking cancelled) exactly like this one, just use the appropriate naming (e.g. booking_rescheduled instead of booking_created)
+  
+### Testing integration
+
+Use the sharing link under Manage → Sharing to create your first Cal.com trigger in Zapier
 
 ## Localhost
+
+Localhost urls can not be used as the base URL for api endpoints
+
+Possible solution: using [https://ngrok.com/](https://ngrok.com/)
+
+1. Create Account
+2. [Download](https://ngrok.com/download) gnork and start a tunnel to your running localhost
+    - Use forwarding url as your baseUrl for the URL endpoints
