Preamble: I am trying to create an elliptic curve key pair in my NativeScript plugin (thus I am forced to use Objective-C) for signing and verification purpose.
At first I want to say that the presented state below is the result of a lot of tries doing it in different ways (I am sitting on this for days, unfortunately) and I considered not only this approach. At the beginning of this project I simply followed the Apple docs and thought I will succeed easily. What a misbelief.
My requirements: to keep it easy I want to store the private key inside of the Keychain (Secure Enclave would be the next step), and calculate the public key via SecKeyCopyPublicKey after I retrieved the key via SecItemCopyMatching, like described in the Apple docs.
Status quo: the model for this originally came from the here. I never got it working with SecKeyCreateRandomKey thus I am trying to use SecKeyGeneratePair atm. What I currently implemented looks like this:
const privAttr: NSMutableDictionary<string, any> = NSMutableDictionary.new<string, any>();
privAttr.setObjectForKey("my.tag.sign.private", kSecAttrApplicationTag);
privAttr.setObjectForKey(kCFBooleanTrue, kSecAttrIsPermanent);
const pubAttr: NSMutableDictionary<string, any> = NSMutableDictionary.new<string, any>();
pubAttr.setObjectForKey("my.tag.sign.public", kSecAttrApplicationTag);
pubAttr.setObjectForKey(kCFBooleanTrue, kSecAttrIsPermanent);
const param: NSMutableDictionary<string, any> = NSMutableDictionary.new<string, any>();
param.setObjectForKey(kSecAttrKeyTypeECSECPrimeRandom, kSecAttrKeyType);
param.setObjectForKey(256, kSecAttrKeySizeInBits);
param.setObjectForKey(privAttr, kSecPrivateKeyAttrs);
param.setObjectForKey(pubAttr, kSecPublicKeyAttrs);
let pubKeyRef = new interop.Reference<any>();
let privKeyRef = new interop.Reference<any>();
const status = SecKeyGeneratePair(param, pubKeyRef, privKeyRef);
Currently I am getting an error -50. According to OSStatus.com this means that my given parameters are not valid at some point. I do not know what exactly is the problem.
My question: how can I generate a keypair where at least the private key is implicitely stored in the keychain and I successfully can retrieve the public key via SecKeyCopyPublicKey afterwards.
Thanks for any valuable hint and your help.
Cordially, David
After trying out several settings I found a solution for this. My answer is documented in the following GitHub issue.

I'm trying to create a campaign that must target mobile devices only, using the google ads API client library in python. The documentation says that I have to modify the DeviceInfo criteria, but that attribute is immutable.
This is my code rn:
campaign_service = client.get_service("CampaignService")
campaign_criterion_service = client.get_service("CampaignCriterionService")
# Create the campaign criterion.
campaign_criterion_operation = client.get_type("CampaignCriterionOperation")
campaign_criterion = campaign_criterion_operation.create
campaign_criterion.campaign = campaign_service.campaign_path(
customer_id, campaign_id
)
campaign_criterion.device = client.enums.DeviceEnum.MOBILE
What am I missing?
For most of Enums you have to use the .type_ after the value you wanna set.
So you should use:
campaign_criterion.device.type_ = client.enums.DeviceEnum.MOBILE
A nice advice is to download library code and goes into reading that.
I am writing code for a custom SAP program regarding some Vendor information. In my program flow, there is a possibility of me trying to use a Vendor VAT Number that belongs to an unknown Vendor. There is a Web site (EU Based - https://ec.europa.eu/taxation_customs/vies/) for such purposes that requires a country key and the specified VAT Number in order for it to provide an answer with the available Company information (only works for company VAT numbers of course). My problem is that I cannot seem to find any way to pass those parameters dynamically to the Web site without needing the user to interfere during this process. Manually, the process would be to select a country key, type in a VAT number and press 'Verify'.
Is there any way for me to call this specific Web site URL and "bypass" this process to only display the result page? For now, I'm using the following Function Module to just call the specified URL, in lack of any better choices.
call function 'CALL_INTERNET_ADRESS'
exporting
pi_adress = 'https://ec.europa.eu/taxation_customs/vies/'

EU Commission has a SOAP service for vat numbers.
See the info page
https://ec.europa.eu/taxation_customs/vies/technicalInformation.html
and that it even supports http
http://ec.europa.eu/taxation_customs/vies/checkVatTestService.wsdl
You have a non screen scrape method, proper interface you should look at.
On the other point of Avoiding SSL.
Make a basic guide for customers to add the European commission cert to their SAP system. If someone is complaining about that, then they are a serious user of the internet. Every sap on premise user, that needs to call the internet adds certs.

I'm using the latest (v7) Google Ads API to upload offline conversions for Google Ads, using the Python Client Library. This is the standard code I'm using:
import os
from google.ads.googleads.client import GoogleAdsClient
client = GoogleAdsClient.load_from_env(version='v7')
def process_adwords_conversion(
conversion_date_time,
gclid,
conversion_action_id,
conversion_value
):
conversion_date_time = convert_datetime(conversion_date_time)
customer_id = os.environ['GOOGLE_ADS_LOGIN_CUSTOMER_ID']
click_conversion = client.get_type("ClickConversion")
conversion_action_service = client.get_service("ConversionActionService")
click_conversion.conversion_action = (
conversion_action_service.conversion_action_path(
customer_id, conversion_action_id
)
)
click_conversion.gclid = gclid
click_conversion.conversion_value = float(conversion_value)
click_conversion.conversion_date_time = conversion_date_time
click_conversion.currency_code = "USD"
conversion_upload_service = client.get_service("ConversionUploadService")
request = client.get_type("UploadClickConversionsRequest")
request.customer_id = customer_id
request.conversions = [click_conversion]
request.partial_failure = True
conversion_upload_response = (
conversion_upload_service.upload_click_conversions(
request=request,
)
)
uploaded_click_conversion = conversion_upload_response.results[0]
print(conversion_upload_response)
print(
f"Uploaded conversion that occurred at "
f'"{uploaded_click_conversion.conversion_date_time}" from '
f'Google Click ID "{uploaded_click_conversion.gclid}" '
f'to "{uploaded_click_conversion.conversion_action}"'
)
return False
I believe the code is fine, but I'm having problems locating the conversion_action_id value to use. In the Google Ads UI there's a screen listing the different Conversion Actions, with no sign of an ID anywhere. You can click on the name and get more details, but still no ID:
The conversion action detail screen in Google Ads UI
I've tried the following:
Using the ocid, ctId, euid, __u, uscid, __c, subid URL parameters from this detail page as the conversion_action_id. That always gives an error:
partial_failure_error {
code: 3
message: "This customer does not have an import conversion action that matches the conversion action provided., at conversions[0].conversion_action"
details {
type_url: "type.googleapis.com/google.ads.googleads.v7.errors.GoogleAdsFailure"
value: "\n\305\001\n\003\370\006\t\022dThis customer does not have an import conversion action that matches the conversion action provided.\0320*.customers/9603123598/conversionActions/6095821\"&\022\017\n\013conversions\030\000\022\023\n\021conversion_action"
}
}
Using the standard Google answer:
https://support.google.com/google-ads/thread/1449693/where-can-we-find-google-ads-conversion-ids?hl=en
Google suggests creating a new Conversion Action and obtaining the ID in the process. Unfortunately their instructions don't correspond to the current UI version, at least for me. The sequence I follow is:
Click the + icon on the Conversion Actions page
Select "Import" as the kind of conversion I want
Select "Other data sources or CRMs" then "Track conversions from clicks"
Click "Create and Continue"
I then get the screen:
Screen following Conversion Action creation
The recommended answer says:
The conversion action is now created and you are ready to set up the tag to add it to your website. You have three options and the recommended answer in this thread is discussing the Google Tag Manager option, which is the only option that uses the Conversion ID and Conversion Label. If you do not click on the Google Tag Manager option you will not be presented with the Conversion ID and Conversion Label.
Not so! What three options? The first "Learn more" link mentions the Google Tag Manager, but in the context of collecting the GCLID, which I already have. The "three options" mentioned in the official answer have gone. Clicking "done" simply takes me back to the Conversion Actions listing.
Using the REST API
I've tried authenticating and interrogating the endpoint:
https://googleads.googleapis.com/v7/customers/9603123598/conversionActions/
hoping that would give a list of conversion actions, but it doesn't. It just gives a 404.
Does anybody know a way of getting the Conversion Action ID, either from the UI or programmatically (via client library, REST or some other method)?
Thanks!
If you're using Python, you can list your conversions via next snippet:
ads: GoogleAdsServiceClient = client.get_service('GoogleAdsService')
pages = ads.search(query="SELECT conversion_action.id, conversion_action.name FROM conversion_action", customer_id='YOUR_MCC_ID')
for page in pages:
print(page.conversion_action)
You can also open conversion action in UI and locate &ctId=, that's the conversion action id.
I found this post with the solution how to get the Conversion Action ID:
(…) I found out that conversionActionId can be found also in Google
Ads panel. When you go to conversion action details, in URL there is
parameter "ctId=123456789" which represent conversion action id.
By the way, I tried something similar and it's still not working, but with this Conversion Action ID I get a different "Partial Failure" message, at least.
At least in Google Ads API (REST) v10,
it works if field conversionAction is set with value:
'customers/{customerId}/conversionActions/{ctId}'
customerId - without hyphens
ctId - conversion action id, as mentioned in above comments,
taken from GET parameters in Google Ads panel when specific conversion is opened.
Can also be found programmatically with API method.
I am not a developer but have used Google search and trial and error test scenarios with Zapier for the last few days and have given up on figuring this out myself. I need help!
I'm using the Run JavaScript code step in Zapier and provided the following details to Input Data.
It says: What input data should we provide to your code (as strings) via an object set to a variable named inputData?
I'm using "street" with a street address example "1402 Spring Garden Rd"
What is the code to use that regardless of the street address provided all the numbers and first space are removed so that the results is "Spring Garden Rd"
Thank you in advance!
var street = inputData;
var streetNoNumbers = inputData.replace(/[0-9]/g, '');
return streetNoNumbers
The error message I'm getting is
TypeError: inputData.replace is not a function
I've learned that strings are immutable and a new string can be made from manipulating another string but doing this in zapier seems to require a function and creating another var with the calculation generates a ... is not a function.
I've tried to write a function but can't get the output or return to show the proper results either.
I can do the following successfully,
var street = inputData
return street
1402 Spring Garden Road
I want to include the code that manipulates street to produce the following:
Spring Garden Road
David here, from the Zapier Platform team. Great question!
The key understanding you're missing is that inputData is a js object with a street property. Before your code is run, we set it up like so:
const inputData = {street: '1402 Spring Garden Rd'}
Since inputData is an object, it doesn't have a replace method (the error you're seeing). Instead, perform your operation on .street and return that.
Try the following:
// need to return an object, not just a string
return {streetNoNumbers: inputData.replace(/[0-9]/g, '')}

I've searched for days looking into this issue but have yet to come up with something. We are migrating our analytics code over to DTM. We are using our own Library hosted at DTM. Everything works great except for some missing data collection parameters in the query string only when using the Adobe Analytics tool to assign variables.
Let me explain. When I use custom code in DTM in a rule to call analytics I get exactly the same query string parameters in the request that we were getting before.
var str = 'string';
s.linkTrackVars = 'prop61,eVar61';
s.linkTrackEvents = 'none';
s.prop61 = str;
s.eVar61 = str;
s.tl(this, 'o', str);
This works fine.
If I try to set eVar61 and prop61 with the Adobe Analytics tool inside a rule, five parameters are no longer in the query string. Specifically 'pev1', 'pid', 'pidt', 'oid' and 'ot'. Is there a way to get DTM to set those parameters or am I just to use custom code for all our rules?
Thanks
Those are clickmap query string parameters. Click on the gear icon to edit the global Analytics tool, and under Link Tracking, make sure 'Enable Clickmap' is checked. Alternatively, you can set s.trackInlineStats=true in your code, which effectively achieves the same effect.
If you ever see missing query string parameters in the future, you can determine what variables to define using the Data Collection Query Parameters in the Marketing Cloud documentation.
