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

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.
I am using ExecutionCreator to use twilio IVR call service
Execution execution = new ExecutionCreator(pathFlowSid, new receiverPhoneNo, new senderPhoneNo)
.setParameters(request.getParametersMap()) //setting request params
.create(twilioClient);
Now I want to get the status of the IVR call and this is done by using Call resource and using statusCallback parameter as given in this https://www.twilio.com/docs/voice/api/call-resource#statuscallback, but there is no way of setting request parameters on Call resource as was possible with Execution resource(please refer to code added).
Is there any way I can get both these functionalities like statusCallback as well as setting request parameters ?
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.
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 have a task to add row into Google Sheet when WebHook received. Now I'm trying to setup IFTTT but have some problem
It says that I should use URL like https://maker.ifttt.com/trigger/{event}/with/key/{my_key} and that is ok I can do it. But it needs to send some data in request and the only way my system can do it appends it to query string like https://maker.ifttt.com/trigger/{event}/with/key/{my_key}?name1=Alex&name2=Helen
But IFTTT doesn't see my data. it says that it can see data in attached JSON but I can't use JSON.
So is there any way to pass my data to IFTT in a query string or shell I forgot IFTTT and investigate how to connect directly to Google Sheet?
IFTTT Maker webhooks can only take data with keys of "value1", "value2", and "value3". Try sending it with:
https://maker.ifttt.com/trigger/{event}/with/key/{my_key}?value1=Alex&value2=Helen
Try using https://bitly.com/ which will shorten and convert the query params to a path param. That worked for me.
First thing first, Web hooks are designed to accept data using POST method only and here you are sending data using GET, which is obviously not going to work, i guess.
Second, in order to get it work, one way is to use cURL request and send your JSON in Body with POST method.
