I have a Twilio studio flow that triggers a serverless function, and this function should call the Twilio REST API to start the same Twilio studio flow but with a different “To” phone number. I am using a vanilla JS “fetch” function, but the function call doesn’t seem to do anything. I have run this block of code outside of the Twilio function and it calls the API just fine. What am I missing?

How does one actually enable 2FA at the account level on Twilio? The Account Owner and all users have 2FA enabled – what more do we need here?

I am building an app that uses Twilio. Currently the app is in development. I have not deployed it to a server yet. When I attempt to create a trusthub profile it is denied because we havent deployed the site to a public URL. Before I deploy, I want to ensure the app handles all errors correctly. I have set up phone numbers, subaccounts, and now need to test toll free verification. Twilio does not have any documentation showing how to test the toll free verification before deployment. Surely They do not expect you to deploy an app first to production then pay money and wait months for responses to test toll free verification? that could take a year to handle all edge cases. Twilio test credentials do not work for creating toll free verifications. You can create MOCK 10DLC brands and campaigns. How do I create MOCK or TEST toll free verifications?

We have a android application ( that has a Twilio SDK integrated ) that we are using to call a landlines/phones, I want a event to be generated when the person punches/keys a digit (say 9) from the landline.

I’m searching Available Phone Numbers using the Twilio API. Normally I use nearNumber to find numbers geographically near an existing phone number, but sometimes geo data isn’t available, so I want to fallback to a City search.

I have configured webhook url in twilio and a springboot app with POST Api listening to it.

But i am always getting false returned
