I could not find anything documentation regarding method or format of message.
The Amazon Simple Notification Service (Amazon SNS) is using a HTTP POST to deliver a notification message, see the FAQ What are the different delivery formats/transports for receiving notifications?:
“HTTP”, “HTTPS” – Subscribers specify a URL as part of the
subscription registration; notifications will be delivered through an
HTTP POST to the specified URL.
The notification message format is documented in HTTP/HTTPS Notifications JSON Format (the Subscribe/Unsubscribe JSON Formats are documented in Appendix D: JSON Formats as well).

I have a Webhook Eventgrid subscription. I do not have access to the webhook logs or implementation.
Apparently ,Eventgrid receives HTTP code other than success from the webhook, but I do not have any detail visibility to that.
How can I see the exact HTTP interaction (Response message, HTTP Code) for the EventGrid WebHook Bad Requests like the ones pointed below?
You need to configure the dead letter on your event grid subscription as documented here.
Once the events are not delivered and dead letter now you can review the lastDeliveryOutcome property on the dead letter events to know what was the reason the event was not delivered to the configured endpoint.
You cannot find the reason for each request at your end as the event may be delivered at a later point in time once it is retried.
I'm setting up a Lambda as a webhook handler that receive data POSTed from a remote API.
As per usual, the external webhook is POSTing the data in the form:
payload='SOME_JSON' for example payload='{"foo":"bar"}'
How can AWS API Gateway be configured to correctly handle application/x-www-form-urlencoded data POSTed from an external webhook, e.g., to correctly map the raw content string into a "form style" parameter name/value pair and pass the value (which is JSON) to the Lambda?
The problem is that AWS API Gateway, by default, tries to relay the entire raw string payload=JSONSTRING to the Lambda, but of course the payload= is not JSON, it's the form parameter name, so that generates a 400 error (body not in JSON format).
To test, I posted the same data to both the AWS API Gateway, and, so that I can see exactly what is POSTed from the webhook, also to webhook.site for debugging.
As shown below the in webhook.site screengrab, the raw data POSTed is in the usual webhook format, "parameter=value" eg payload=JSONSTRING, specifically: payload='{\"arg1\":\"val1\"}'
And as shown in the webhook.site screengrab, their site completely understood how to map that to a "parameter name" (payload) and the parameter value.
webhook.site screengrab:
The closest I've come is to get the API Gateway & Lambda to stop throwing 400 errors, by using API Gateway's "Body Mapping Template" to at least force the raw content "param=value" into JSON format using this body mapping:
{"body": "$input.body"}
as described in this helpful blog post: https://blog.summercat.com/using-aws-lambda-and-api-gateway-as-html-form-endpoint.html
(edit: that blog post was old, Body Mapping Template is not required, API Gateway now supports enabling "Use Lambda Proxy integration" on the Integration Request for the POST method which passed to the Lambda the full input object (headers, payload, etc) as JSON to get rid of the 400 errors. But the "body" key/value in the JSON is still not parse-able JSON, it is prefixed with the payload=")
But the problem is the the Lambda event hash still isn't in a usable format it still includes the "payload=...(escaped string)" e.g.
`{"body"=>"payload=%7B%22arg1%22%3A%22val1%22%7D"
So I hope there is some way to configure API Gateway to do what the rest of the world can do, and map the POSTed raw content "payload=JSONSTRING" to a JSON object that is passed to the Lambda, such as {"payload" : "JSONSTRING"} or perhaps just JSONSTRING?
I am new to Twilio. We have a requirement in the project as follow -
Send an outbound SMS to a given number. The message body is static text and should be defined using a template on Twilio(TwiML), so that client can change the message body anytime without making any changes in the backend application.
I have gone through the Twilio documentation to understand how to use TwiML, but couldn't find any document or article which explains how to use TwiML for sending an outbound SMS. Currently I am using following code to send a SMS and the message is configured in the Spring Boot application.properties file.
Message message = Message.creator(new PhoneNumber(phoneNumber),
new PhoneNumber(fromPhoneNumber),
messageBody).setStatusCallback(URI.create(callBackUrl)).create();
Does anyone know how to use TwiML template to send an outbound SMS. Can someone help me to solve this problem. Thank you.
What is Twiml?
Twiml is instructions for Twilio, how to respond to an incoming phone call,SMS, etc...
What is Twiml
It is not for outbound actions.
To initiate an SMS , you should use the Twilio api which is what you are doing when you use the sdk such as Message.creator
I have a Twilio messaging service with Copilot and the sticky sender feature enabled.
I would like to view the phone number that Copilot assigns to my recipients when I send them a message.
With the Ruby client, I get a MessageContext object when I send a message, but it only has the
messaging service SID - the from method returns nil.
Currently, this is how I'm sending messages:
def send(from, to, message)
client = Twilio::REST::Client.new(ACCOUNT_SID, AUTH_TOKEN)
client.api.account.messages.create(
body: message,
messaging_service_sid: from,
to: to,
status_callback: BASE_URL + '/sms_status/status',
)
end
Twilio developer evangelist here.
I'm not sure, but you might not have the phone number at the time you make the API request using a messaging service. This request really just queues up the message to be sent.
I would check the message object once it has been sent. You have a status callback URL setup, so you should be able to either inspect the parameters sent to that URL or look up the message from the API using its SID and then get the number that was used.
I am trying to get a shopify webhook to fill my customer class in parse.com, however something must go wrong. I don't know how to verify the parse response since Shopify sends this webhook out from it's ruby backend. I used requestbin to catch the webhook and I replicated a post request using postman to my parse url and everything works fine. Does anyone know how to debug requests like these? Is there a console in Parse where I can see all the incoming requests and the responses Parse.com sent back?
Try using Runscope for debugging webhooks. Full guide here: https://www.runscope.com/provider-guide/troubleshooting-webhooks - this is more than just a request bin. It's a full transparent proxy that will, like a bin, record the webhook notification, but will also pass it along to the intended destination (your webhook receiver) and record that response as well.
