Join us for the Twilio Challenge: $5,000 in Prizes!

#devchallenge #twiliochallenge #ai #twilio

We are so delighted to partner with Twilio for a new DEV challenge.

Running through June 23, the Twilio Challenge is all about combining the power of AI with the magic of Twilio. We have one prompt for this challenge but four ways to win.

From Messaging to Voice Intelligence to everything in between, Twilio is the go-to platform for global communications that every developer should have experience building with. Flex your creativity and AI skills in whatever language you want, and add another impressive project to your portfolio!

Our Prompt

For this challenge, your mandate is to Build an AI-driven Experience that Leverages Twilio.

You are free to use any Twilio product and any third-party AI tool/API - the world is your oyster! For those of you who don’t want to start from scratch, we encourage you to build on top of an existing Twilio project so long as you add a new AI element to it.

And for those of you who would like some incentivized guidelines, we have three additional prize categories for you to consider…😉

Prize Categories

Twilio Times Two: Awarded to a top submission that utilizes two or more Twilio APIs.
Impactful Innovators: Awarded to a top submission that drives positive impact (social, environmental, etc).
Entertaining Endeavors: Awarded to a top submission that pushes the boundaries of creativity and gives us a good laugh.

Prizes

Our prompt winner (1) will receive:

$2,000 USD
Exclusive DEV Badge
A gift from the DEV Shop

Our prize category winners (3) will receive:

$1,000 USD
Exclusive DEV Badge
A gift from the DEV Shop

All Participants with a valid submission will receive a completion badge on their DEV profile.

Hi @anthonyjdella, I wanted to participate but Twilio blocked my account without any explanation long time ago, and support didn't help/explain anything.

my email: serafimsanvol@gmail.com

Anthony • Jun 13

@serafimsanvol Sorry about that, I'll contact support to fix the issue.

Andrii • Jun 13

Thanks, @anthonyjdella!

Anthony • Jun 13

@serafimsanvol Could you please create a support ticket? If you could, please attach a screenshot and any info about what steps you took until you reached the error. Once you've done that I've escalated this to support and they'll be able to help.

Andrii • Jun 14

@anthonyjdella, for now, it magically started working again, I wonder what happened :)
Thanks

Anthony • Jun 14

Great news, good luck with the challenge!

cauhlins • Jun 12

Hi @anthonyjdella Does an API service count? Or do I need to build a full app that has a frontend?

Anthony • Jun 12

That counts, so you can build an app without a frontend if you'd like.

Mohamed Ashiq Sultan • Jun 13

where to enter the promo code, I signed up with gmail but dont see any options to use the promo code under Billing tab.

Anthony • Jun 13

@ashiqsultan There are 2 ways to use a promo code:

If you have a Trial account which are upgrading
If you have an Upgraded account

For 1, twilio.com/console/billing -> Upgrade -> Fill in your information -> Fund Account -> Promo Code tab

For 2, go to twilio.com/console/billing -> Billing Overview -> Add Funds -> Promo Code tab

Birusha Ndegeya • Jun 13

Shweta Kale • Jun 15

@anthonyjdella it says code is expired. I tried both codes.

Jess Lee • Jun 15

Ketan Rajpal • Jun 15

This also not working.

Shweta Kale • Jun 16

@jess this worked for me. Thanks!!

Jess Lee • Jun 16

@ketanrajpal can you try twilio-ai-devto-6099i?

Ketan Rajpal • Jun 17

Dhanush Reddy • Jun 15

hey @anthonyjdella , it says promo expired
twilio-ai-devto-cc4f4

Jess Lee • Jun 15

Can you try code twilio-ai-devto-b24we?

Rajeev R. Sharma • Jun 16

Apparently this code has expired as well. Any other option?

Jess Lee • Jun 16 • Edited

@ra_jeeves can you please try that one again or twilio-ai-devto-6099i?

Rajeev R. Sharma • Jun 17 • Edited

The new code shared now (6099i), worked fine. Thanks @jess

Tried just now, same result, "Expired".
Was thinking of doing something with programmatic voice, and the default phone number given by Twilio is a US number, which is quite expensive if called from India. So maybe a local Twilio number will be better, but for that we need an upgraded Twilio plan.

Yogesh Sharma • Jun 17

@ra_jeeves can you please try that one again or twilio-ai-devto-6099i?

@jess This code is also expired

Rishab Kumar • Jun 17

@1995yogeshsharma Could you give it another try? Thank you.

Yogesh Sharma • Jun 17

worked now, thanks @rishabk7 !

Rajeev R. Sharma • Jun 18 • Edited

@rishabk7 Deleted my previous comment as the code in the main post worked. And I've refreshed the page many times to confirm that the upgrade is done.

But I've a question related to programmatic voice. Tried buying a local number for India and it seems that it is not possible to do so. So how do I test phone calls receiving? Making a call to the US number is not feasible as the operator charges are quite high. Is there a simpler way to do this?

Shreya Nalawade • Jun 14

quick question do we have to integrate ai with twilio or ai should be part of application with the usage of twilio @anthonyjdella

Anthony • Jun 18

@shreya111111 Either works!

Rishab Kumar • Jun 12

Hi builders, I'm a DevEvangelist here at Twilio.
If you need any support with this challenge feel free to tag me.
Can't wait to see what you build!

chintanonweb • Jun 17

I am confused about WhatsApp send receive from Twilio UI I am able to do send receive but I want to configure AI into it where I can integrate that function for WhatsApp, but I'm not able to find it.

Anthony • Jun 18

Hi @chintanonweb how are do you have your application set up? You can add some AI API calls into your application for example.

Sweta Kanguri Sonulkar • Jun 13

why is it asking me identity government card?

Anthony • Jun 14

@sweta_kangurisonulkar_ From which region are you registering from? Depending on your country, we may ask for an ID to verify the individual. This is to help build an ecosystem with less fraud and spam messages.

Peter Kim Frank • Jun 12

Excited about this one!

Ben Halpern • Jun 12

Good luck!

Jess Lee • Jun 12

Good luck everyone!

Aditya Oberai • Jun 17

Just finished my submission 🥳

@anthonyjdella, I do have some product feedback. When trying out Twilio Functions, I noticed that the max length of environment variables is set to 255 characters. I was using Appwrite Databases as a part of my project, and the API keys happened to be 256 characters in length. This made it somewhat challenging to use environment variables for that purpose.
