Unable to get Twilio recording file via Workato HTTP action

[JayMappus]

I'm trying to request a Twilio recording file using Workato's  HTTP request. But, I'm getting the following error:

400 Bad Request
<?xml version='1.0' encoding='UTF-8'?>
<TwilioResponse><RestException><Code>20001</Code><Message>Bad request</Message><MoreInfo>https://www.twilio.com/docs/errors/20001</MoreInfo><Status>400</Status></RestException></TwilioResponse>

Below is my request:

{
"request_name": "Request recording file",
"request": {
"method": "GET",
"content_type": "application/json",
"url": "https://api.twilio.com/2010-04-01/Accounts/A_______________________0/Recordings/R___________________..."
},
"response": {
"output_type": "rawdata",
"ignore_http_errors": "false"
}
"wait_for_response": "false"
}

I've got the "Response content type" set to Binary and the Encoding to UTF-8. What am I missing?

Thank you in advance.

I'm not sure if the response is the problem. The 400 error is coming from Twilio, not from Workato, so it seems like the URL is bad.

Some thoughts:

• Are you sure it's GET and not POST?
• What should the response be? JSON, XML, data?

Hi gary1. Good to "see" you once again. It is a GET from Twilio https://www.twilio.com/docs/voice/api/recording#mp3  it says..

Appending ".mp3" to the URI returns a binary MP3 audio file with mime-type type "audio/mpeg". For example:

GET https://api.twilio.com/2010-04-01/Accounts/ACXXXXX.../Recordings/RE557ce644e5ab84fa21cc21112e22c485....

I added the .mp3 but get the same error.

Always happy to help!

I took a look at the documentation and the only thing that sticks out to me is the warning about audio channel availability. Try adding this param to your URL:

?RequestedChannels=1

Like this:

https://api.twilio.com/2010-04-01/Accounts/AC../Recordings/RE...mp3?RequestedChannels=1 

Here's a link the warning in the documentation. It reads very much like the issue you're having.

gary1,

I used the following since these recordings are dual channel and got the same error message.:
