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

I am trying to use the promo code "twilio-ai-devto-anrnp". But it gives me the error "twilio-ai-devto-anrnp cannot be used on your account.". Can you please help.
@shreya111111 Yes you can. There will be a section on the template that asks which categories your project may qualify for - be sure to mention all of them!

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.

@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.

Hi @dhruvb26 your application is hitting localhost, but you'll need a publicly accessible URL from the Internet. Try to deploy your application or have it tied to a public URL, instead of localhost. One tool I like to use is ngrok, here's a cool guide to help you.
Hi @anthonyjdella . Is it possible to configure a Whatsapp number to call a webhook URL? In this doc, the example is for a phone number. I tried replacing the phone number with the WhatsApp number and Twilio CLI sent back a 400 response.

Great news, good luck with the challenge!
hey @anthonyjdella , it says promo expired

Hi @anthonyjdella Does an API service count? Or do I need to build a full app that has a frontend?
That counts, so you can build an app without a frontend if you'd like.
where to enter the promo code, I signed up with gmail but dont see any options to use the promo code under Billing tab.
@ashiqsultan There are 2 ways to use a promo code:
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

@anthony. I would like to clarify to know how much trial do we have while using Twilio for learning
Hi @birusha when you sign up for a Trial account you will be given $15 of trial credits.
Additionally, use the promo code
twilio-ai-devto-anrnp
for an additional $20 of credits.@anthonyjdella
Thank you so much
Hi @anthonyjdella, I'm having issues upgrading my Twilio account with the promo code provided. It says the code has expired. please help

Hi @chintanonweb how are do you have your application set up? You can add some AI API calls into your application for example.
why is it asking me identity government card?

@adityaoberai Thank you for the feedback, that is good point.

@adityaoberai Thanks for the feedback, we'll alert our product team and try to get this on the roadmap.
Awesome, thank you :)

hey @anthonyjdella I was kinda building react app using twilio but somehow I could not login after few hours of inactivity Is there any way to resolve this issue I already generated support ticket but they fwded it to another team.
Could you please send me your Account SID, error, and email address to me at adellavecchia@twilio.com ?
I can flag this to our support team.
Oh I got it resolved by support team Ig I had made two accounts before and for this contest created third one so they kinda raised security issue but I gave them my details and support team was quite helpful and I submitted my project today. Still thanks for helping out :) Anthony
Also @anthonyjdella can we extend the deadline for submission cuz ig many people are facing same issue as myself.
Can anyone share some sample ideas to build ?
"Build on top of existing twilio project", What does it mean ? To use Twilio API and add AI features to it ?
cc: @anthonyjdella @rishabk7
So that means, if you already have a Twilio project that you built in past, add AI functionality to it, if applicable. Hope that helps.
ohh okay, that helps. Thanks
If possible, Can you share some sample ideas to build ?
@devananth For inspiration, our developer blog has a lot of fun projects. Also, if you're in the US, we have 2 upcoming holidays which you could use for inspiration.
Thanks, will checkout the blogs.
AND Cloudflare Workers AI??? Oh yeah - can't wait for this one!
let's go 🚀
Hello Twilio team @anthonyjdella . It seems like the promo code for dev.to participants has expired.

@bytrangle So the promo-codes are rotated daily. Could you try this promo-code:
twilio-ai-devto-6099i
Finally, after over a week and iteration through multiple ideas I am able to complete this project.
dev.to/bibekkakati/simplify-phone-...
Looking forward for your feedback, folks ⚡️

Hi @dhruvb26 your application is hitting localhost, but you'll need a publicly accessible URL from the Internet. Try to deploy your application or have it tied to a public URL, instead of localhost. One tool I like to use is ngrok, here's a cool guide to help you.
Hello! I tried a few of the codes shared throughout the comments but they're all expired..
@artyymcflyy try this one?
twilio-ai-devto-6099i
It says the code has expired, I mustve missed the window to redeem. Can I have another then I'll try?
It should work, could you give it another try, thank you.
twilio-ai-devto-6099i
That worked! Thank you
