Getting Transaction Declined for sale transaction

We are working on an Apache Cordova plugin based on remote-pay-android-go SDK that will allow Ionic/Cordova applications to integrate with the Clover Go device.
Here is the link to the plugin. We have implemented basic methods to init, connect, disconnect and make a sale. We are getting the error message "Transaction Declined. Please use another form for Payment" with reason "charge_declined", whenever we perform sale through the device.
I tried the example code in the remote-pay-android-go SDK and the code gives the same error for sale from the device and works well for the manual transaction.
Can someone help me understanding where we may be missing?
Thanks in advance!

I was able to get past this by following a recent answer by David Marginian on the Clover forum.
I believe there is something going on with the gateway emulator on sandbox, we are looking into it. In the meantime try transactions > 50 dollars, they should go through fine.
I think as the default currency is set to cents, the values I tried always remained below 50 dollars.

Deeplinking Squareup pos app is not working

The documentation link: https://developer.squareup.com/docs/pos-api/build-mobile-web#step-5-test-your-code suggest straight forward code like this:
<a href="intent:#Intent;
action=com.squareup.pos.action.CHARGE;
package=com.squareup;
S.browser_fallback_url=https://my.website.com/index.html;
S.com.squareup.pos.WEB_CALLBACK_URI=https://my.website.com/index.html;
S.com.squareup.pos.CLIENT_ID=sq0ids-yourClientId;
S.com.squareup.pos.API_VERSION=v2.0;
i.com.squareup.pos.TOTAL_AMOUNT=100;
S.com.squareup.pos.CURRENCY_CODE=USD;
S.com.squareup.pos.TENDER_TYPES=com.squareup.pos.TENDER_CARD,com.squareup.pos.TENDER_CASH;
end">Start Transaction</a>
I tested it and it does not open any link, my devide already have app installed.
When I try this code:
Take a QR code 2
It open play store app with squareup pos app information, I need to directly open the app and not play store screen of the app, is there any way?

*UPDATE:
I got transactions to work after adding S.com.squareup.pos.LOCATION_ID={{ my_location_id }}. The location ID can be found in Square Developer Portal > Locations. Also if the POS app is passcode protected, you have to open and login with passcode before sending transaction.
*END UPDATE
I've been working through this same issue. I still haven't gotten a transaction to work, but have at least gotten the app to open.
Make sure the CLIENT ID is your production application ID. NOT sandbox.
The WEB_CALLBACK_URI needs to match the Web Callback URL defined in your Square Developer Portal > Point Of Sale API.
I hope this helps. If you do figure this out and get transactions to work, please post your solution for me and others who are sure to run into this issue since the documentation is lacking.

Change in twitter login

As we know, there have been changes in access to the twitter API referring to callbacks URLs.
So far, I have been using the identification callback with firebase, as I indicated here:
This has been working perfectly so far.
I read in the documentation that now you have to indicate the callback, according to android or iOS in the following way:
twitterkit- : // if using Twitter Kit for iOS or
twittersdk: // if using Twitter Kit for Android.
My application is only developed for android.
I have tried all the possible variants, but I always get the following error:
The client application failed validation: Not a valid callback URL format.
The tested options have been:
twittersdk://pfa89MGYola62VIln ........ (MY_CONSUMER_KEY)
twittersdk://MY_APP-android.firebaseapp.com/__/auth/handler
twittersdk://https://MY_APP-android.firebaseapp.com/__/auth/handler
I have activated and deactivated the check "enable callback locking" ...
I've tried everything, I'm a little desperate
For another test, I tried to register the URL callback as if it were the iOS platform
twitterkit-MY_CONSUMER_KEY://
and it was accepted on the first attempt.
I do not mind losing the relationship with firebase, the truth is that I was not using it, but I have a serious problem if I can not connect with twitter again.
I appreciate any help.

I found the solution, I put it here in case it can be of help to someone.
The truth is that it is not well specified in the documentation, you have to take two steps.
First: activate the "enable callback locking" checkbox
Second: indicate the android sdk for twitter, WITHOUT CONSUMER KEY, unlike iOS users.
It would be like this:
I hope it helps

'Cannot read property 'listRegistrationsByTag' of undefined' from Microsoft.WindowsAzure.MobileServices.Push.RegisterAsync

This is a Xamarin.Forms app running on Android, based on the Azure getting started Mobile App example.
I'm trying to register a device's id for notification services. Originally I was getting unauthorized, so I relaxed authorization settings on the backend. Now I am getting this error and cannot find a reason why.
I checked and double checked that notification hub has the correct Firebase details that align with the app and cannot see what the problem is here, any help appreciated.

John,
If you set WEBSITE_PUSH_ENABLED=false in your appsettings, does the problem go away?
Can you check your Mobile App's app settings?
Specifically, I am looking for the existence of the app setting "MS_NotificationHubName". If that app setting doesn't exist, you need to add it, with the name of your notification hub.

There is a bug in the Azure App Service Push blade right now. A fix is being rolled out. In the interim, instead of using RegisterAsync(), use the method described in the book http://aka.ms/zumobook - chapter 5.

Track APP Installs from Facebook

I'm following documentation as states:
https://developers.facebook.com/docs/ads-for-apps/mobile-app-ads/#advanced
Specifically: Measure App Installs
However, I did the following code:
com.facebook.AppEventsLogger.activateApp( this, APPLICATION_ID_FACEBOOK );
However, in dashboard, it doesn't detect the install:
Any tips?
LogCat outputs the following:
FacebookException: No attribution id returned from the Facebook application

Ok. Solved.
Basically for whoever faces this:
FACEBOOK APP must be installed in device.
USER must be logged in.
Thats it.
=)

Another great but hidden hint is to enable verbose logging via
FacebookSdk.addLoggingBehavior(APP_EVENTS)
The output is actually very helpful and even contains error analysis and descriptions.
