I want to know that can i call cloud function from postman software .When i'm calling CF from postman it always give me
"error": {
"status": "INVALID_ARGUMENT",
"message": "Bad Request"
}
In Postman make post request, header Content-Type should be application/json and then in raw make json in this format
{
"data": {
"text":"hi how are you",
"phoneNumbers":"+92123455679"
}
}
Using #Vaaljan's answer I was able to authenticate a GCP cloud function that I created using the HTTP trigger method with authentication required:
gcloud auth print-identity-token
Then added it to the request Authorization header:
Authorization: Bearer eyJhbGciOiJSUzI1NiIsImtpZCI6I ... bnRzLmdvb2dsZS5jb20i
In Postman:
Could possibly also be that the cloud function is protected and can be invoked by adding Authorization header with the identity token as the Bearer.
You get the identity token by running
gcloud auth print-identity-token

I am working in google script API trying to get a schema of a table from BiqQuery... not sure why it is so troublesome.
I am sending a request like this :
let url = 'https://bigquery.googleapis.com/bigquery/v2/projects/'+ projectId +'/datasets/'+ datasetId +'/tables/' +tableId;
var response = UrlFetchApp.fetch(url)
I am getting this response:
Exception: Request failed for https://bigquery.googleapis.com returned code 401. Truncated server response: { "error": { "code": 401, "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie ... (use muteHttpExceptions option to examine full response) (line 68, file "bigQuery")
I have been able to load data to bigQuery alright... not sure why this does not work. I have looked at the OAuth fields in manifest and the script does have access to bigQuery...
no success also when adding this to the options field of the UrlFetch request
var authHeader = 'Basic ' + Utilities.base64Encode(USERNAME + ':' + PASSWORD);
var options = {
headers: {Authorization: authHeader}
}
Use bearer tokens
The reason why the BigQuery API rejects your requests is that the endpoint requires one of the following scopes to be provided with the access token to work, and it is missing from the request:
https://www.googleapis.com/auth/bigquery
https://www.googleapis.com/auth/cloud-platform
https://www.googleapis.com/auth/bigquery.readonly
https://www.googleapis.com/auth/cloud-platform.read-only
The actual issue here is that the basic authorization scheme lacks info about any claims, only sending over correct credentials. Since you are requesting the endpoint directly with UrlFetch service, despite correctly specifying the scopes in the manifest, they will not be sent over.
ScriptApp service now provides an easy method to get a valid bearer token without using an OAuth 2.0 library or building the flow from scratch: getOAuthToken. Pass it to an Authorization header as bearer token, and you should be all set:
const token = ScriptApp.getOAuthToken();
const options = {
headers : {
Authorization : `Bearer ${token}`
}
};
Use Advanced Service
As an alternative, there is an official advanced service as a wrapper around BigQuery REST API that will manage authentication and response parsing for you.
You must enable the BigQuery advanced service before using it
Also, note that the advanced service identifier is configurable, so you have to reference the identifier you chose.
In your case, the service can be used as follows (assuming you used the default BigQuery identifier). There is also the 4th argument of type object that contains optional arguments (not shown here):
Bigquery.Tables.get("projectId","datasetId", "tableId");
The method chain above corresponds to tables.get method of the BigQuery API.
I am creating a serverless app using IBM Cloud Functions. My Cloud Functions API is secured with OAuth user authentication using an IBM Cloud App ID service. When a user logs into my app, an access token is generated by this service. I want to extract user data from that access token so that I can customize the user experience.
How do I access that token from within a Cloud Functions action that is coded for Node.js 10?
Example
The openwhisk webaction doc
https://github.com/apache/openwhisk/blob/master/docs/webactions.md
states that the following code
function main(params) {
return { response: params };
}
generates the following response
{
"response": {
"__ow_method": "get",
"__ow_headers": {
"accept": "*/*",
"connection": "close",
"host": "172.17.0.1",
"user-agent": "curl/7.43.0"
},
"__ow_path": ""
}
}
From that data I should be able to get HTTP request details. Specifically, I should be able to get the Authorization header value off the "__ow_headers" property of the action argument (params).
However, the same code inside an IBM Cloud Functions web action generates nothing. Nothing exists on the params object.
I am trying to invoke lambda service. When I hit the Get method(under Api gateway->stages->GET) invoke Url I see json headers and status code also. But in the acloud guru lecture video, I see just the body. Can anyone please tell what am I missing here.
Here is my python function:
def lambda_handler(event, context):
print("In lambda handler")
resp = {
"statusCode": 200,
"headers": {
"Access-Control-Allow-Origin": "*",
},
"body": "myName"
}
return resp
Actual Output:
{"statusCode": 200, "headers": {"Access-Control-Allow-Origin": "*"}, "body": "myName"}
Expected output:
myName
here you have used lambda proxy integration and did not enable it in API gateway level.
You can enable it under Integration request, see the image below
There are 2 types of API Gateway and Lambda integration
Proxy Integration - Request to API gateway is directly forwarded to lambda and response is sent from lambda. we have to create the response body with appropriate status code and headers inside the lambda in this integration
Lambda Integration - request can be modified before sending to lambda and response can be modified from lambda response in API gateway level using mapping templates
This blog post gives more details about the 2 integrations

I'm struggling to trigger a Google Apps Script Function which builds many dropdowns of a Google Spreadsheet.
I need this data to be updated daily on this Google Spreadsheet so I must call the function.
Seems like I'm required to have a client-side authentication which I'm reluctant to force it to happen.
I have set already the Google API PHP Client which does batch updates, get requests and control users and its roles.
Here's how the code looks like:
public function updateTemplate ()
{
$client = $this->getClient();
$service = new Google_Service_Script($client);
$scriptId = $this->gScriptId;
// Create an execution request object.
$request = new Google_Service_Script_ExecutionRequest();
$request->setFunction('SetUpNewSpreadsheet');
try {
// Make the API request.
$response = $service->scripts->run($scriptId, $request);
echo "here<pre>";
print_r($response);
exit;
I'm getting the following response error:
Caught exception: {
"error": {
"code": 401,
"message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
"errors": [ {
"message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
"domain": "global",
"reason": "unauthorized"
} ]
, "status": "UNAUTHENTICATED"
}
}
I've checked the message errors and docs already. I'm wondering if maybe I'm missing something or if I can find a way to execute that request without forcing a client-side login?
Has anyone been through it?
I'm trying to use the V2.2 of StackExchange API in Google Apps Script.
The problem comes in the last step of the explicit OAuth 2.0 flow, when I try to send the POST request to obtain the access token. I receive a 404 error, but making the same request manually (using postman extension) everything is ok.
To simplify the problem, if I send this POST request with no payload I receive the same 404
var response = UrlFetchApp.fetch("https://stackexchange.com/oauth/access_token", {
method: 'post',
muteHttpExceptions: true
});
Logger.log(response);
while in postman I receive this 400:
{
"error": {
"type": "invalid_request",
"message": "client_id not provided"
}
}
I guess this will be a problem with UrlFetchApp, but does anyone know how to solve it? Thanks!
The problem is related with the Origin header.
You cannot remove from the header directly but you can perform the call via a proxy :)
You need to provide the data for the post by adding an 'option' object to the call.
For example:
var options = { "method" : "post", "payload" : payload };
UrlFetchApp.fetch("https://stackexchange.com/oauth/access_token", options);
Btw, have you tried you use the OAuth that UrlFetch got: https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#addOAuthService(String) - It might be better way.
