Part 1 - Creating your MMS Flow

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)

Click the hyperlinked flow name to edit an existing flow, or select ‘Create Flow’ to start a new one from scratch.

When you're ready to add an MMS to your flow, use the 'Webhook' node. Simply drag and drop the 'Webhook' into the flow at the point where you’d like the MMS to be triggered.

First, name your Webhook e.g. Loyalty MMS #1 Then click the '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.

Add the following inputs under Headers: 1. **Key:** Content-Type 2. **Value**: application/json

Click the 'Add Header' button and add the following inputs: 1. **Key:** Authorization 2. **Value:** Include your Tall Bob Basic Auth Header here

If you're not sure what your Basic Auth Header is, or need a refresher we've got you covered <https://support.tallbob.com/support/solutions/articles/17000128010-sending-an-sms-with-klaviyo-flows>

Click the JSON Body section and replace it with the following: [[{\\ "to": "{{ person.phone_number }}",\\ "from": "",\\ "url": "",\\ "subject": "",\\ "message": ""\\ }]]

We're going to take a short break now and jump out of Klaviyo into your Tall Bob account

Part 2 - Uploading your Media Content

You first need to access the Media Library section. You can click\ <https://app-2.tallbob.com/documents/browse_documents> to go directly to it via the Content menu.

Now click the 'Browse' button. Select the media file you want to use in your MMS and then click 'Start' to upload it

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

Part 3 - Return of the Scary Code Stuff

Ok, so that was all pretty easy and whilst going back to the scary code might sound off putting we are super close to 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 pasting it in between the quotation marks next to the "url": section

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

Then enter the text that you want to appear in the Body of the MMS Message.

If you want to, you can personalise your message by using Klaviyo profile properties e.g. First Name - Simply click on Profile - Click the Property you want - Return to your message and paste the copied field

We are almost there, just hang in a little longer.

Part 4 - Finalising your MMS

So at this point you are pretty much done, from here its just a matter of saving your flow, or continuing to build it out as you choose fit. But we really do encourage you to test that your MMS message looks and feels the way you expect first. Below we will walk you through how you can do that.

Testing your MMS is pretty easy and assuming you have your details as a Contact already in Klaviyo you'll have that MMS hitting your phone in just a few moment. - First Click "Preview" then "Search for a Profile" - Search for and select the contact you want to send a test to - Assuming they are found click "Send Test Request" to get things moving

Congratulations, you are all done setting up your MMS message! You can continue to build out your flow and setup as many SMS and MMS messages as you like. Or if you're done, just click 'Review and Turn On' and you should be good to go.

Part 5: Adding Shortened Links

Hang On... what about link shortening and all that jazz?

So, you want to include a link in your MMS message and have it shortened? Awesome! We think it’s a great idea, and it’s super easy to do. Just head back to that JSON file from earlier and add this extra line: "shorten_urls": true
