Start by heading into your Klaviyo interface. We'll start there, and move over to Tall Bob for a short time.

Let's start by navigating to [www.klaviyo.com/flows](http://www.klaviyo.com/flows)

- Type the name of your Flow at Name (we recommend keeping a common naming convention across your team).
- And, click "Create Flow"

Navigate to the 'All Triggers' tab, choose your trigger option and select your trigger data \[i.e, list/segment/metric etc\]

Click "A profile subscribes to a list for the first time."

A profile subscribes to a list for the first time.

Once your trigger is set, click on the 'Save' button

Click on 'Confirm and Save' button to confirm the trigger

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

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.

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

Click the 'Add Header' button. Click the 'Key' field, add a new header 'Authorization' and include your Basic Authorization value

Click Add Header.\
Click the "Key" field and 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": ""\\ }]]

{
    "email": "{{ person.email 
        }}"
}

Ok so we are going to take a short break now and jump out of Klaviyo into your Tall Bob account

Now you need to access the Media Library section, you can click 
[https://app-2.tallbob.com/documents/browse_documents](https://app-2.tallbob.com/documents/browse_documents) to go directly to it 


Now you need to access the Media Library section, you can click [https://app-2.tallbob.com/documents/browse_documents](https://app-2.tallbob.com/documents/browse_documents) to go directly to it 

Click "Browse, manage and upload media such as images, pdf's and word documents to use in your campaign landing pages."

Browse, manage and upload media such as images, pdf's and word documents to use in your campaign landing pages.

Now Click the Browse button, select the media file you want to use in your MMS and then Click Start to upload it

Form Uploads
   ▶ Change Request Form
   ▶ Form Upload Test
   ▶ Test Upload Form
MMS Uploads
Private
   ▶ Aaron.g
   ▶ Aaron.g2
Public
   ▶ untitled folder

Make sure you Upload your Media to a folder under your 'Public' directory, otherwise your MMS may not be able to send properly

Next find the image you uploaded under your Public Directory

Double click it to open, and then copy the URL from the window

Ok, so that was all pretty easy and whilst going back to the scary code might sound off putting it really isn't and we are super close to being finished getting your MMS message all set up

Now it's time to take that URL we just got from Tall Bob and bring it into Klaviyo, you can do this simply by going to the JSON Body section and then pasting it in between the quotation marks next to the "url": section

{
"to": "[[{{ person
  .phone_number ]]}}",
"from": "",
"url": "",
"subject": "",
"message": ""
}

{
"to": "[[{{ person
  .phone_number ]]}}",
"from": "",
"url": "https://app-2-test
  .tallbob.com//documents
  /download_document/54456ea0
  -e000-11ed-8c4a
  -0233161a7834",
"subject": "",
"message": ""
}

Next set who you want the message sent 'From' (which is your Sender ID) and the Subject of the MMS Message

Next set who you want the message sent "from" (which is your Sender ID) and the Subject of the MMS Message

{
"to": "[[{{ person
  .phone_number ]]}}",
"from": "Tall Bob",
"url": "https://app-2-test
  .tallbob.com//documents
  /download_document/54456ea0

  -e000-11ed-8c4a
  -0233161a7834",
"subject": "Test Message from 
  Tall Bob",
"message": ""
}

Then Enter the text if any that you want to appear in the Body of the MMS Message (this is optional)

"to": "[[{{ person
  .phone_number ]]}}",
"from": "Tall Bob",
"url": "https://app-2-test
