Start by heading into your Klaviyo interface. We'll start there, and move over to Tall Bob for a short time.
1
Let's start by navigating to [www.klaviyo.com/flows](http://www.klaviyo.com/flows)
2
Head to "Create Flow".
3
Click on 'Build your own' button
4
- Type the name of your Flow at Name (we recommend keeping a common naming convention across your team).
- And, click "Create Flow"
5
Navigate to the 'All Triggers' tab, choose your trigger option and select your trigger data \[i.e, list/segment/metric etc\]
6
Once your trigger is set, click on the 'Save' button
7
Click on 'Confirm and Save' button to confirm the trigger
8
Trigger 2 is your Webhook.
- Drag and drop the 'Webhook' option below the first trigger.
- Click on the added trigger to view the webhook options
9
Here's where you may cringe, but stick with it.
- Click this Destination URL Field and enter [api.tallbob.com/v2/mms/send_list](http://api.tallbob.com/v2/mms/send_list)
- Yes - this is the same for everyone. Remember, you've already connected your unique APIs and webhooks.
10
Next, and again, trust us - it looks scarier than it is.
- Click the 'Key' field and type 'Content-Type'
- Then Enter 'application/json' in the 'Value' field
11
Click the 'Add Header' button. Click the 'Key' field, add a new header 'Authorization' and include your Basic Authorization value
If you're not sure what your Basic Authorization Value is, or need a refresher we've got you covered [https://scribehow.com/shared/Sending_Plain_SMS_with_Klaviyo_Webhooks__VC1o7zrKSjGsmD_R-xXuMg](https://scribehow.com/shared/Sending_Plain_SMS_with_Klaviyo_Webhooks__VC1o7zrKSjGsmD_R-xXuMg)

Click the JSON Body section and replace it with the following:
[[{\\ "to": "{{ person.phone_number }}",\\ "from": "",\\ "url": "",\\ "subject": "",\\ "message": ""\\ }]]
Ok so we are going to take a short break now and jump out of Klaviyo into your Tall Bob account
Part 2 - Uploading your Media Content
