How can I run a flow from another flow in Twilio Studio Flow?
Help with defining the To and From HTTP parameters:
I am a beginner in programming so I am failing to understand the brief notes given in support docs, namely specifying HTTP additional parameters for "To" and "From".
Additional details from comment:
I am trying to run REST API triggered Flow B from primary Flow A by using an http request widget in Flow A in the format below: (as suggested in a similar problem posted on this portal) Widget: HTTP Request [ACCOUNT_SID:AUTH_TOKEN#studio.twilio.com/v1/Flows/THE_OTHER_STUDIO_FLOW_SID/Executions][2] Content Type: Form URL Encoded KEY:VALUES To:+1234567890 From:+2773123456 I am getting error 401. I tried to swap the To number with the From number without success
There are 2 ways you can trigger one twilio studio flow from another
Method 1:
Use the TwiML Redirect Widget. Place the widget where you need it and specify the target studio flow URL there. Studio URLs have the following format
https://webhooks.twilio.com/v1/Accounts/{AccountSid}/Flows/{FlowSid}
Method 2:
Do the same as above programmatically. You can send twilio a twiML response such as the one below
let twiml = new Twilio.twiml.VoiceResponse();
if (something) {
twiml.redirect({
method: 'POST'
}, 'https://webhooks.twilio.com/v1/Accounts/{AccountSid}/Flows/{FlowSid1}');
} else {
twiml.redirect({
method: 'POST'
}, 'https://webhooks.twilio.com/v1/Accounts/{AccountSid}/Flows/{FlowSid2}');
}
For more info, check out https://www.twilio.com/docs/voice/twiml/redirect
Assuming you are not trying to bridge the call between the two flows, this should be possible. To simplify:
You have a call come in on Flow A ("Incoming Call" trigger on Flow A).
Flow A executes its logic.
That logic triggers Flow B by calling its REST API endpoint so that it makes a new outbound call ("REST API" trigger on Flow B).
This last thing is the hard part. Make sure you are looking at the docs for the REST API Execution resource. To trigger a new flow, you need to make a POST request which supplies the To and From parameters.
If you are a beginner at programming, it might be helpful for you to start with a separate HTTP client like Postman to start to get familiar with the structure of an HTTP request, and learn the full extent of what is required to successfully make this API request before you start trying to cram it into Studio and automate it.
That said, this request should be possible to do within the Studio Make HTTP Request widget. If you make your content type Application/JSON, you can pass the To/From parameters directly in a JSON-formatted request body, like this:
{
"To": "+19995551234",
"From": "+12345556789"
}
To be perfectly honest, I don't know what the widget means by "Http Parameters". This could be HTTP Headers, URI parameters, or something else. I think the JSON form is clearer.
I came across the same situation. The solution for authentication is to change the url to include AccountSid and AuthToken
https://[AccountSid]:[AuthToken]#studio.twilio.com/v2/Flows/[SID]/Executions
Instead of Application / Json, use Form Parameters. Then add individual parameters below, for To, From, and Parameters​ (JSON string) for other variables.

I have two page
Login/Registration Page as of now
OTP Verification Page
API has been created and in api, we are passing phone number as request and gets otp as response. However i would like your help to know how should i able to pass the phoneNumber textfield data to APIcall json request in flutterflow?
If there is anyway or any documentation will be really helpful?
I have tried with variable method, however i was not able to pass it to json.
I have also tried jsonpath method, but no luck.
Define dynamic part of API url with brackets
https://jsonplaceholder.typicode.com/posts/[postId]
https://jsonplaceholder.typicode.com/comments?postId=[postId]
then create the variable (postId) with the same name. When adding the API call, it is required to add these variables.
See API Calls 101 for details.
So I really don't know what the problem is here, I've tried many things, but I can't get the Twilio request hashes to match up. Let me explain.
I decided to implement an instance of Twilio's RequestValidator to ensure the requests were coming from Twilio. But after following the tutorial here: https://www.twilio.com/docs/usage/security?code-sample=code-validate-signature-of-request-1&code-language=PHP&code-sdk-version=5.x
The validator is only returning false. Here is the code that I used:
$url = 'https://example.com/api/endpoint/to/endpoint/';
$request_params = $_REQUEST;
$twilio_validator = new RequestValidator('myauthtoken');
if (!$twilio_validator->validate($_SERVER['HTTP_X_TWILIO_SIGNATURE'], $url, $request_params)) {
throw new CallException('Not from Twilio');
}
Even though the URL is an example, that is exactly how I have the actual URL formatted...no port, basic auth, or fragment. Just the protocol, domain, and path with a trailing "/". In addition, the URL is the exact VoiceURL I set when I set up this Twilio App (this is calling the VoiceURL to one of my Twilio Apps).
My auth token is the auth token for my whole account
The request params is where I'm sure I'm messing something up. Twilio is making a GET request to this endpoint, and I tried using the $_GET superglobal as well, to no avail. I'm using $_REQUEST here because of this issue: https://github.com/twilio/twilio-php/issues/510 and because I thought it would be the best choice. I have also tried using file_get_contents('php://input') to the exact same problem (the hashes not matching, ultimately).
I even forked and opened a PR on the PHP SDK to update the class a little bit, just to see if I could learn any more...so I know the class and it's methods pretty well...I just don't see my issue.
What am I doing wrong here to make it so that the RequestValidator isn't validating that the requests from Twilio are coming from Twilio?
So after a lot of research and working with Twilio help, I figured out the answer to my question.
When Twilio is making a GET request to my server, you aren't supposed to pass the GET parameters as the third parameter to the validate method on the RequestValidator class. When Twilio is making a GET request to your server, validating actually needs to look like this:
// this is the interesting part...you don't even set the pathname on the domain...
// EVEN IF YOU THE PATHNAME IS SET IN YOUR VOICE URL.
// This is because of the different way the RequestValidator handles GET and POST params
$domain = 'https://example.com'; // make sure to add no trailing '/'
// setting up the RequestValidator
$twilio_validator = new RequestValidator('myauthtoken');
// figuring out if the request is from twilio
$is_from_twilio = $twilio_validator->validate(
// the signature header that Twilio sends
$_SERVER['HTTP_X_TWILIO_SIGNATURE'],
// The domain name CONCATENATED to the Request URI. $_SERVER['REQUEST_URI'] holds everything that comes after the domain name in a URL (pathname, query parameters, and fragment)
$domain.$_SERVER['REQUEST_URI']
// if the request is a get request, as mine are, there is no need for the third parameter
);
// resolving the response
if (!$is_from_twilio) {
echo 'Not from Twilio';
exit;
}

I believe Twilio's outbound call could be HTTP POST request. Is there a way I can pass my custom POST body (json etc) when making outbound voice call request? I'm writing a generic call center where I would like to pass the conversation workflow when making outbound calls so that the code which receives the call knows how to run the conversation. I looked at the documentation (https://www.twilio.com/docs/api/twiml/twilio_request) and looks like we can only pass standard parameters (from, to etc). Thanks for any help.
I believe the only parameter you can customize is the Url Parameter.
Your JSON is pretty much a string (you might have to url encode it and also watch for the length), but you could put it in the query string of the Url Parameter.
?json=url_encoded_json
first of all I'd like to thank the team for this amazing project, it is indeed exiting to be able to start writing server-side software in Swift.
I'm successfully running a POC using PerfectServer on an Ubuntu VM and working on the API to interact with the mobile client.
There is one aspect I didn't quite understand yet, and that is accessing the request body data from my PerfectServer Handler.
Here is the workflow I have in mind:
The client submits a POST request to PerfectServer including some
JSON encoded body data
Once that hits the "valuesForResponse:" of
my server side Handler, I retrieve the WebRequest representation of
my request successfully
The request object does expose a many
properties of the HTTP request, including headers and the url-like
formatted query parameters.
Unfortunately, I cannot see a way to retrieve the underlying request body data. I would expect that to be some kind of public properties exposing the raw data that my handle can retrieve and decode in order to process the request.
The only example provided in the Examples workspace that comes with the project and sends a POST request that includes a body is in the project Authenticator. Here the HTTP body part takes the form os a UTF-8 encoded string where the values are query-params-like formatted.
name=Matteo&password=mypassword
This gets somehow exposed on the server handler by the WebRequest "param" property, that in the inner implementation of HTTPServer seems to expect an "&" separated string of key-values:
What I would expect is to have a way to provide body data in whatever form / encoding needed, in my case a JSON form:
{"name":"Matteo", "password":"psw"}
and be able to access that data from the WebRequest in my handler, decode it and use it to serve the request.
To summarise, I assume you could say that a WebRequest.bodyData public property is what I am after here :).
Is there something I am missing here?
Thanks in advance for any clarification!
I'm trying to get Twitter authentication working on my ASP.NET site. When you create the app on the Twitter website, you have to specify a callback URL, which for sake of argument, I have set to http://mydomain.com
I've read the oAuth 1.0a spec, and to override this callback URL with your own custom one you have to send the oauth_callback parameter in the request_token phase (url-encoded of course).
So my request URL looks like this:
http://twitter.com/oauth/request_token?oauth_callback=http%3A%2F%2Fmydomain.com%2Ftwittercallback
Supposedly, if all goes to plan, in your response data, you are supposed to receive a new parameter of oauth_callback_confirmed=true in addition to your token and token secret parameters.
However, my response comes through as:
oauth_token=MYTOKEN&oauth_token_secret=MYTOKENSECRET
I know I haven't given you guys the greatest amount to go on, but I'm at my wits end as to why I am not receiving the oauth_callback_confirmed parameter. Without this, my application keeps defaulting back to the callback URL hard-coded on the Twitter website. Please if anyone could help me out, I will be eternally grateful!
Thanks,
A.
I've read the oAuth 1.0a spec, and to
override this callback URL with your
own custom one you have to send the
oauth_callback parameter in the
request_token phase (url-encoded of
course).
So my request URL looks like this:
http://twitter.com/oauth/request_token?oauth_callback=http%3A%2F%2Fmydomain.com%2Ftwittercallback
just because YOU read the spec doesn't mean that TWITTER read it. :P
kidding - this is essentially correct - but the way twitter likes to receive this data is a little different (and not well documented).
the way i've found to get the oauth_callback to confirm is as follows: specify the oauth_callback in the parameters of the request function, NOT within the URL.
python example (using oauth2):
''' Create our client.'''
client = oauth.Client(consumer)
''' do the request '''
resp, content = client.request(request_token_url,"POST",body=urllib.urlencode({'oauth_callback':callbackURL}))
''' note that it's called "body" in this particular OAuth function for Client but in OAuth Request object it's called "parameters." YMMV depending on programming language/ library of course. '''
this is ALSO the only way i've managed to get an oauth verifier back. supposedly one should not have to specify the callback URL every time, since we provide it in app settings...but experience seems to indicate otherwise.
finally, please be aware that at leg 3 you have to do the same thing AGAIN - this time including the oauth_verifier as well as the callback URL in the parameters.
hope this helps - can't begin to tell you how much effort i put into figuring this out.
good luck!

I've used this guide to set up my PC to be used as the callback location. Basically you set up your hosts file in a certain way, clear your cache and add a couple of Firefox registry values. At the end when you are debugging an oauth call the redirect comes back to your local PC.
As I said it worked for me.
<?php
// oauth-php example
$token = OAuthRequester::requestRequestToken(
$consumer_key,
$user_id,
array('oauth_callback'=> urlencode($callback_uri))
);
?>
