Why the amount of BNB in my binance wallet changes without me buying or selling that? Actually first I bought 1BNB some time ago, now it's just 0.05 in my wallet and during the time I was seeing it changes weiredly!
You enabled BNB fees. So for your trading, Binance uses BNB instead of base/quote currency. You can read more about it here https://www.binance.com/en/support/faq/115000583311-Using-BNB-to-Pay-for-Fees

Just curious on best practices for handling potential data loss with a third party integration.
For example, lets say that im integrating stripe for payments. If our platform has a credit system (a user needs X number of credits to do an action on the site), how would you reconcile a loss of data between the platform and after a purchase is made? Going into the example: a user is on the site, purchases a pack of credits for $10. Our platform calls stripe payment when the user clicks "purchase," the purchase is successful but all of a sudden a loss of power happens. We receive the $10 in our stripe, but on our platform the purchase was never "complete" because the loss of power happened immediately after the purchase was made, and there was no time for our system to receive the authorization code to store as completed. I'd imagine this could be common, or in another case where the purchase is complete, but there is some issue between receiving the success code from the payment processor and it causes delay. So, how do you handle this loss of data?
I could think of maybe storing a payment intent on our database with payment status "incomplete" and once a payment is made and we get a code back from stripe, then we update our database with "complete" and we have some job that polls this database every hour or something to check for "incomplete" payments.
What is common in this case?
I have a problem with google cloud's billing verify. I added a debit card, which has received an X amount of eurocents from Google. To verify my billing, I need to type that amount into the 'billing account'. However, when I click 'billing' it says there are no accounts, when I try to create one, it tells me my billing account is awaiting confirmation. Any ideas?
TL;DR You could experience some issues when adding a payment method to your billing account in Google Cloud. The best you can do if you face any issue after reading the documentation is to contact Billing support.
If you receive an error such as Your card does not support automatic recurring payments or General decline of the card, please select a different form of payment.
As I can see from your question, you tried to verify Your Bank Account, as stated in the documentation:
A small test deposit will appear in your bank account within a few days of adding the account as a payment method. After you see the test deposit, you should verify the deposit as described in Find and enter a test deposit.
Instant bank verification
We offer instant bank verification for Google Cloud customers. Unlike the test deposit verification method, which takes several days to complete, instant bank verification allows you to verify your bank account within seconds.
You can use instant bank verification in either of the following situations:
If you haven't entered your bank account information yet
If you've recently entered your bank account information
Verify your payment method (US only)
Note: Currently, this service is available only to customers with a U.S. bank account.
In the resolve errors when attempting to add or update a payment method section, it mentions that
you might receive an error such as:
Your card does not support automatic recurring payments.
or
General decline of the card. No other information was provided by the issuing bank.
You might encounter these errors if you are using a debit card that requires two-factor authentication...
When you enter a debit card as your form of payment, Google checks whether your issuing bank approves subscriptions or recurring payments using that card. If your bank does not approve, this card will not work for automatic recurring payments.
If you receive an error such as Your card does not support automatic recurring payments or General decline of the card, please select a different form of payment. You can also contact Cloud Billing Support for help.
Therefore, some of the issues when adding a payment to your Cloud Billing account could be related to some bank restrictions and could even be related to some domestic and international regulations, as it occurs to customers in India.
As stated in the Payment Methods documentation:
The payment methods available for your self-serve (online) Cloud Billing account depend on your currency and country. In many countries, you can set up a credit card, debit card, or bank account as a primary payment method.
So in the first instance, I suggest you review the List of countries and regions.
If your country or region is not listed here, this might indicate that your country or region's currency is not supported for Google Cloud charges. In these instances, your Cloud Billing account might incur charges in USD.
For countries or regions not listed here, check the payment options tool for information.
Then, you should check the Supported payment methods:
The types of cards Google services lets you add to payment profiles vary by location and by product.
American Express
MasterCard
Visa
Discover (U.S. only)
JCB (Japan and U.S. only)
Visa Electron (Outside the U.S. only)
Elo credit cards (Brazil only; We don't allow you to add Elo debit cards)
Debit cards with the Visa or MasterCard logo
Bank account
If supported in your country, you can add a bank account to pay.google.com to pay your Cloud Billing account.
Verify Your Bank Account
Depending on your country, you might need to verify your bank account to use it as a payment method by direct debit. A small test deposit will appear in your bank account within a few days of adding the account as a payment method. After you see the test deposit, you should verify the deposit as described in Find and enter a test deposit.
Also, there are some unsupported payment methods:
Debit cards that require two-factor authentication
are not accepted for payment.
Prepaid cards and Virtual Credit Cards (VCCs) are not accepted for payment.
Bank accounts that only support disbursements are not accepted for payment.
Payment via wire transfer is not supported for monthly charge or threshold billing
accounts.
You may pay with a bank account by adding it as a payment method, if
supported in your
country.
So, as long as your payment method is supported, you could add it to your Cloud Billing account.

I want to get product Buybox price based on product ASIN.
Is there any API available in Amazon ?
The ItemLookup call of the Product Advertising API has a ResponseGroup named Offers which will allow you to get the buy box price (or, if nobody has the buy box, it will return the lowest offer).
According to this question it seems there is no way to tell if a returned price is actually the buy box price or just the lowest offer.
Alternatively, if you are a seller on Amazon, you could also use the GetCompetitivePricingForSKU call of the MWS Products API.
I am building a web app in cakePHP that involves a credit system.
So credits are bought with real money, then at a some point in the future they are spent and the portion the credits value goes to me and the rest goes to a third party.
So far no problem but...
If I use something like PayPal's Express Checkout, PayPal take a cut when the credits are initially bought and another cut when the third party is paid.
Or I can use PayPal's Adaptive Payments and do a Delayed Chained Payment but that has a maximum delay of 90 days.
So my question is do I have any other options?
There are only two options:
Use another payment service provider, but they'll all take their share for their service. But Paypal has become expensive.
Add the fees on top of what the user has to pay for the credits, you'll have to calculate them in advance.
I've made an app in order to send large mailings. Google enforces a 100 recipient a day maximum as I read on the quota page:
100 messages daily until first charge cleared; 20,000 messages per day thereafter
After deploying the app I've intentionally maxed out the 100 recipient limit, which adds a charge to my billing account of $0.01 This is also shown in my billing history.
However I've also set a weekly budget of $2.10 The one time charged associated with this budget has been made succesfully according to my Google Wallet. Looking at my current quota's it seems it's still limited to 100 even after waiting for 24 hours for my quota's to reset. Has anybody had the same problem? I don't know what to do next or how to interpret the "leave grace period" mentioned in my billing history.
If you were a new customer, you would have to wait one week, but you have already cleared a charge so you should be able to exceed the 100 user quota immediately. You may want to try to send mail and see if you get quota exceeded exceptions.
The "Leave Grace Period" messages mean that a charge previously failed putting you in the Grace Period. You then later successfully charged your credit card and left the Grace Period.
App Engine has announced that it will shortly be changing its billing system. So this answer will be outdated within a few weeks.
