Step 4: Configure Webhook in e-Janji
- Log in to your e-Janji account.
- Go to Workflow → Create New Workflow
- Choose Send HTTP(S) request from Select Action options as your sending method.
- From URL, select “POST“. Paste the OnSend Webhook URL: https://onsend.io/api/v1/send
- Add new header, enter “Authorization“, and set the value to “Bearer TOKEN“, where TOKEN represents your OnSend device token, for example, 9cc97a40db218abb3f25d7c6c728e2ed8…..
- Select Content type; there are two types (Form data and JSON) with examples shown below.
- Click Save button.
From now on, every booking event (new booking, reminder, cancellation, etc.) will trigger e-Janji to send a notification payload to OnSend.
Example Notifications: Content type → JSON
Here are sample payloads e-Janji sends to OnSend for different events. You can add Dynamic content when making your messages.
For more JSON sample code or content, please visit our knowledge base as follows:
- JSON Sample Code – Appointment Confirmation
- JSON Sample Code – Appointment Reminder
- JSON Sample Code – Appointment Rescheduled
- JSON Sample Code – Appointment Cancellation
Example Notifications: Content type → Form Data
Like the JSON Content type, the POST URL and Header remain the same; the only difference is that the content type is set to “Form Data,” allowing you to easily include any Dynamic content in the form.
Remember that the form data must remain the same:
- phone_number
- message
- type = text
