I have an AWS Step Function called trough API Gateway with the following Choice:
"Router": {
"Type": "Choice",
"Choices": [
{
"Variable": "$.deviceType",
"StringEquals": "queclink-gl501mg",
"Next": "Queclink GL501MG Uplink"
},
{
"Variable": "$.deviceType",
"StringEquals": "queclink-gl502mg",
"Next": "Queclink GL502MG Uplink"
},
{
"Variable": "$.deviceType",
"StringEquals": "queclink-gl505",
"Next": "Queclink GL505 Uplink"
},
{
"Variable": "$.deviceType",
"StringEquals": "tive",
"Next": "Tive"
},
{
"Variable": "$.deviceType", // Something like $.queryparams.deviceType ?
"StringEquals": "kkmKG01",
"Next": "KkmKG01"
}
],
"Default": "Error"
},
The last option (kkmKG01) doesn't match because the device can't send a deviceType in it's payload.
What I want to do is to specify the deviceType in a query param since I can configure the url my device calls.
I added a query param in both the Method Request and Integration Request in API Gateway:
But I don't know how to check the deviceType from the query param instead on the deviceType from the payload in my Step Function.

I want to achieve a proxy from another url with changing one value within the response
So having something like that (not working, just an idea)
{
"request": {
"method": "GET",
"urlPathPattern": "/api/search-service"
},
"response": {
"proxyBaseUrl" : "https://external-search-service",
"transformerParameters": {
"results[*].hasAccess": true
}
}
}
}
When you call GET https://external-search-service/api/search-service the response is
{
"meta": {
"results": 2
},
"results": [
{
"id": "1",
"path": "/path/1",
"hasAccess": false
},
{
"id": "2",
"path": "/path/2",
"hasAccess": false
}
]
}
And when I want to temper with response using wiremock when you call GET https://wiremock/api/search-service the response I expect is
{
"meta": {
"results": 2
},
"results": [
{
"id": "1",
"path": "/path/1",
"hasAccess": true
},
{
"id": "2",
"path": "/path/2",
"hasAccess": true
}
]
}
How this can be achieved with JSON notation?
This isn't achievable purely using JSON configuration, but you can create a Java extension to transform responses, which will work with proxied responses.
To do this you would need to create an implementation of ResponseTransformer and register it with WireMock on startup.
Full details of how to do this are here: https://wiremock.org/docs/extending-wiremock/#response-transformation
I am developing an application that communicates with PayPal's API to create invoices.
This is my Request Body:
{
"detail": {
"currency_code": "USD",
"note": "Thank you for using my services!"
},
"invoicer": {
"name": {
"given_name": "Shreyas",
"surname": "Ayyengar"
},
"email_address": "{email}",
"website": "{website}"
},
"primary_recipients": [
{
"billing_info": {
"email_address": "{client_email}"
}
}
],
"items": [
{
"name": "{invoice_name}",
"description": "{invoice_description}",
"quantity": "1",
"unit_amount": {
"currency_code": "USD",
"value": "{invoice_amount}"
},
"tax": {
"name": "PayPal Service Tax",
"percent": "7.25"
}
}
],
"configuration": {
"partial_payment": {
"allow_partial_payment": false
},
"allow_tip": true
}
}
While there are placeholders like: {client_email}, I can guarantee that they are replacing properly and as expected.
However I'm thrown a VALIDATION_ERROR which I am not able to understand: {"name":"VALIDATION_ERROR","message":"Invalid request - see details.","information_link":"https://developer.paypal.com/docs/api/invoicing/#errors","details":[{"field":"merchant_info","issue":"cannot be null."},{"field":"items[0].unit_price","issue":"null"}]}
From what I can minimally understand, this error says that I have missing information like Items[].unit_price and merchant_info however I have no idea where this is supposed to be in my Request Body. I am following the direct documentationhere but I cannot see anything that mentions unit_price or merchant_info.
Submit your request to the correct API endpoint, https://api-m.sandbox.paypal.com/v2/invoicing/invoices
Note the major version number. See the Invoicing API reference for details.
I'm trying to implement a simple app for Google Assistant.
All works fine, but now I have a problem with the "permission" helper :
https://developers.google.com/actions/assistant/helpers#helper_intents
I have an intent connected with webhook to my java application. When an user types a sentence similar to "near to me", I want to ask to him his location and then use lat/lon to perform a search.
es: Brazilian restaurant near to me
my intent "searchRestaurant" is fired
I receive the webhook request and I parse it
if I find a parameter that is connected to a sentence like "near to me", so instead to response with a "Card" or a "List" I return a JSON that represent the helper request :
{
"conversationToken": "[]",
"expectUserResponse": true,
"expectedInputs": [
{
"inputPrompt": {
"initialPrompts": [
{
"textToSpeech": "PLACEHOLDER_FOR_PERMISSION"
}
],
"noInputPrompts": []
},
"possibileIntents": [
{
"intent": "actions.intent.PERMISSION",
"inputValueData": {
"#type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"optContext": "Posso accedere alla tua posizione?",
"permission": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
}
}
]
}
]
}
but something seems to be wrong, and I receive an error:
"{\n \"responseMetadata\": {\n \"status\": {\n \"code\": 10,\n \"message\": \"Failed to parse Dialogflow response into AppResponse because of empty speech response\",\n \"details\": [{\n \"#type\": \"type.googleapis.com/google.protobuf.Value\",\n \"value\": \"{\\"id\\":\\"1cc45c5e-c398-4ea7-98a5-408f31ce142d\\",\\"timestamp\\":\\"2018-08-02T14:45:05.752Z\\",\\"lang\\":\\"it\\",\\"result\\":{},\\"alternateResult\\":{},\\"status\\":{\\"code\\":206,\\"errorType\\":\\"partial_content\\",\\"errorDetails\\":\\"Webhook call failed. Error: Failed to parse webhook JSON response: Cannot find field: conversationToken in message google.cloud.dialogflow.v2.WebhookResponse.\\"},\\"sessionId\\":\\"1533221100163\\"}\"\n }]\n }\n }\n}"
The "conversationToken" is filled, so I don't understand the error message.
Maybe I'm trying to perform the operation in a wrong way.
So, which is the correct way to call this helper?
--> I've created a second intent "askGeolocation" that have "actions_intent_PERMISSION" as "Event", and ... if I understand correctly the documentation, should be trigger if the request for helper is correct.
How can I get this working?
UPDATE :
I find some example of the json response for ask permission and seems that it should be different from the one above that i'm using :
https://github.com/dialogflow/fulfillment-webhook-json/blob/master/responses/v2/ActionsOnGoogle/AskForPermission.json
{
"payload": {
"google": {
"expectUserResponse": true,
"systemIntent": {
"intent": "actions.intent.PERMISSION",
"data": {
"#type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"optContext": "To deliver your order",
"permissions": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
}
}
}
}
}
so, i've implemented it and now the response seems to be good (no more error on parsing it), but i still receive an error on it validation :
UnparseableJsonResponse
API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: "permission: Cannot find field."
so, a problem still persist.
Anyone know the cause?
Thanks
After some tests i found the problem.
I was returning a wrong json repsonse with "permission" instead of "permissions":
"permission**s**": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
So the steps to ask for location are correct. I report them here as a little tutorial in order to help who is facing on it for the first time:
1) In DialogFlow, add some logic to your Intent, in order to understand when is ok to ask to user his location. In my case, i've added a "parameter" that identify sentences like "nearby" and so on.
2) When my Intent is fired i receive to my java application a request like this :
...
"queryResult": {
"queryText": "ristorante argentino qui vicino",
"action": "bycategory",
"parameters": {
"askgeolocation": "qui vicino",
"TipoRistorante": ["ristorante", "argentino"]
},
...
3) If "askgeolocation" parameter is filled, instead to return a "simple message" o other type of message, i return a json for ask the permission to geolocation :
{
"payload": {
"google": {
"expectUserResponse": true,
"systemIntent": {
"intent": "actions.intent.PERMISSION",
"data": {
"#type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"optContext": "To deliver your order",
"permissions": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
}
}
}
}
}
4) You MUST have a second Intent that is configured with "actions_intent_PERMISSION " event :
No training phrases
No Action and params
No Responses
But with Fulfillment active :
5) Once your response arrive to Google Assistant this is the message that appear :
6) Now, if user answer "ok" you receive this json on your webhook :
{
"responseId": "32cf46cf-80d8-xxxxxxxxxxxxxxxxxxxxx",
"queryResult": {
"queryText": "actions_intent_PERMISSION",
"action": "geoposition",
"parameters": {
},

"fulfillmentMessages": [{
"text": {
"text": [""]
}
}],
"outputContexts": [{
"name": "projects/xxxxxxxxxxxxxxxxxxxxx"
}, {
"name": "projects/xxxxxxxxxxxxxxxxxxxxx",
"parameters": {
"PERMISSION": true
}
}, {
"name": "projects/xxxxxxxxxxxxxxxxxxxxx"

"name": "projects/xxxxxxxxxxxxxxxxxxxxx"

"name": "projects/xxxxxxxxxxxxxxxxxxxxx"
}],

}]
},
"requestType": "SIMULATOR",

}],
"arguments": [{
"textValue": "true",
"name": "PERMISSION",
"boolValue": true
}],
"intent": "actions.intent.PERMISSION"
}],
"user": {
"lastSeen": "2018-08-03T08:55:20Z",
"permissions": ["NAME", "DEVICE_PRECISE_LOCATION"],
"profile": {
"displayName": ".... full name of the user ...",
"givenName": "... name ...",
"familyName": "... surname ..."
},
"locale": "it-IT",
"userId": "xxxxxxxxxxxxxxxxxxxxx"
},
"device": {
"location": {
"coordinates": {
"latitude": 45.xxxxxx,
"longitude": 9.xxxxxx
}
}
},
"conversation": {
"conversationId": "xxxxxxxxxxxxxxxxxxxxx",
"type": "ACTIVE",
"conversationToken": "[]"
},
"availableSurfaces": [{
"capabilities": [{
"name": "actions.capability.SCREEN_OUTPUT"
}, {
"name": "actions.capability.AUDIO_OUTPUT"
}, {
"name": "actions.capability.WEB_BROWSER"
}]
}]
}
},
"session": "projects/xxxxxxxxxxxxxxxxxxxxx"
}
that contains, name/surname and latitude/longitude. This information can be saved in your application, in order to not perform again this steps.
I hope this helps.

In your intent, you can ask for a parameter with a custom Entity. This you can do like this:
entity you can define as "near"
put all the synonyms for near for which you want to trigger location permission in this entity
do not mark this parameter as "required"
do not put any prompt
in the training phrases, add some phrases with this parameter
in your webhook, keep a check on the parameter, if present ask for permission if not continue.
add a permission event to another intent
do your post permission processing in that intent
Entity
Intent
I hope you get it.
There are samples on this topic specifically that guide you through exactly what's needed for requesting permissions in Node and Java.
Note: There are helper intents samples available in Node and Java as well.
I want to create a chatbot with Dialogflow and Google Assistant along with Google Transactions API for enabling a user to order a chocolate box. For now my agent contains the following four intents:
Default Welcome Intent (text response: Hello, do you want to buy a chocolate box?)
Default Fallback Intent
Int1 (training phrase: Yes, I want, fulfilment: enabled webhook call)
Int2 (event: actions_intent_TRANSACTION_REQUIREMENTS_CHECK )
I am using Dialogflow Json instead of Node.js to connect my agent with Transactions API. I want to test that the user meets the transaction requirements (when ordering the chocolate box) by using the actions.intent.TRANSACTION_REQUIREMENTS_CHECK action of Google actions. For this reason, following Google docs, when Int1 is triggered I am using a webhook which connect Google Assistant to the following python script (back-end):
from flask import Flask, render_template, request, jsonify
from flask_cors import CORS
import requests
app = Flask(__name__)
CORS(app)
#app.route("/", methods=['POST'])
def index():
data = request.get_json()
intent = data["queryResult"]["intent"]["displayName"]
if (intent == 'Int1'):
return jsonify({ "data": {
"google": {
"expectUserResponse": True,
"isSsml": False,
"noInputPrompts": [],
"systemIntent": {
"data": {
"#type": "type.googleapis.com/google.actions.v2.TransactionRequirementsCheckSpec",
"paymentOptions": {
"actionProvidedOptions": {
"displayName": "VISA-1234",
"paymentType": "PAYMENT_CARD"
}
}
},
"intent": "actions.intent.TRANSACTION_REQUIREMENTS_CHECK"
}
}
}
})
else:
return jsonify({'message': 'HERE'})
if __name__== "__main__":
app.run(debug=True)
The json which I return above when intent = 'Int1' is the one specified at Google docs for "Checking requirements with your own payment method".
According to Google docs, this must be done next:
Receiving the result of a requirements check
After the Assistant fulfills the intent, it sends your fulfillment a
request with the actions.intent.TRANSACTION_REQUIREMENTS_CHECK intent
with the result of the check.
To properly handle this request, declare a Dialogflow intent that's
triggered by the actions_intent_TRANSACTION_REQUIREMENTS_CHECK event.
For this reason, I defined Int2 and as its event the actions_intent_TRANSACTION_REQUIREMENTS_CHECK.
However, I do not receive anything at my back-end like a result of the check and therefore I do not know if the action actions.intent.TRANSACTION_REQUIREMENTS_CHECK is really triggered. Why is this happening?
In general, how can I trigger one actions.intent.INTENT_NAME intent from my webhook/back-end?
When I am using the v2 version of Dialogflow, I am getting the following info/message about the webhook on Dialogflow when Int1 is triggered:
"webhookStatus": {
"code": 3,
"message": "Webhook call failed. Error: Failed to parse webhook JSON response: Cannot find field: data in message google.cloud.dialogflow.v2.WebhookResponse."
}
In the same case, I am getting the following info/message about the webhook on Google Assistant simulator when Int1 is triggered:
"responseMetadata": {
"status": {
"code": 14,
"message": "Webhook error (206)"
}
Finally, let me mention that I am testing all this with Python and ngrok at my local computer so perhaps this poses a problem because at the beginning of Google docs the following is mentioned:
Warning: The Actions Web Simulator should not be used to test an app
with transactions. Please use an Assistant-enabled Android or iOS
device to accurately test your app during development.
I finally solved this problem.
I had to replace the key "data" in the json which I was sending back when Int1 was triggered with the key "payload". In other words, I had to adjust my fulfilment response to the v2 version of Dialogflow.
Therefore, now I do get a second post request at my back-end which is sent because of the trigger of actions.intent.TRANSACTION_REQUIREMENTS_CHECK and of Int2.
Specifically, I get the following:
{
"responseId": "*****************************",
"queryResult": {

I think your response object is incorrect. the intent attribute should be inside the systemIntent object
"data": {
"google": {
"expectUserResponse": true,
"isSsml": false,
"noInputPrompts": [],
"systemIntent": {
"intent": "actions.intent.TRANSACTION_REQUIREMENTS_CHECK",
"data": {
"#type": "type.googleapis.com/google.actions.v2.TransactionRequirementsCheckSpec",
"paymentOptions": {
"actionProvidedOptions": {
"displayName": "VISA-1234",
"paymentType": "PAYMENT_CARD"
}
}
}
}
}
}
I've setup a resource in API Gateway with an API key and a Mock Integration. When I test in the console, I can see the canned JSON response which I setup in the integraion response.
However, when I test externally using Postman, I can see the expected status code in the response (201) but the response body is empty.
Would anyone be able to shed some light over why this might be?
Many thanks
Ben
Just to make sure, did you deploy the latest version of your API? I used the sample API below which worked fine for me. Could you try this one?
