Good !!, Working

Hi! I got your code working mostly on my site. I am running into an issue where it seems to always double send payments to users.
I have tried both LTC and BTC payments, and always there is a double send. Any ideas?

can you explain more with photos etc?

Sure. I have your above API coded on a .php file. I run it in my web browser to process the API.
If I put an actual BTC or LTC address in where it says "$to_email = 'xxxxx@gmail.com'; //Reciver Email", it processes the transaction fine.
I just discovered this yesterday.

However, if I put a user's email (no matter what user), it always sends the payment twice for some reason. It sends it, and then sends it again.

The attached image shows 2 API calls, each which ended up with a duplicate payment.

I even tried to add the "idem" parameter on the API call to ensure it was unique, but that was to no avail.

I noticed the API version has been updated on Coinbase, but I still used the version you had in your code here:
"CB-VERSION:2019-11-15",

Anyhow, not sure what is causing the double pay.

hmm, I tested the code before it send transactions only one time & there is no issue with the API version. i will test it again

Yup tested again its working just fine

Weird, well maybe there is something not in the code. Like maybe because I ran mine online through my website, it ran twice when interacting with Coinbase email addresses? It looks like you are running yours on a command prompt? What program are you running to edit / run the file?

Also, maybe it is one of the API permissions I have checked causing it to double send. I checked them all. Are there ones you don't have checked?

I think I figured out the issue. For some reason, it auto refreshes and runs the call twice. If I put a timer in, the 2nd call I can manually block.
Also, my idempotent variable I was passing in, most likely is doing nothing, since the time is differing by a some milliseconds, so it looks like two unique calls.

oh no problem, i just run code as PHP <filename.php>

i am getting problem while sending money through this code and getting error message.
{"errors":[{"id":"not_found","message":"Not found"}]}

When you log into Coinbase, find the coin you want, then click on "Wallet". If you look at the URL at the top of the page, you can see the account ID there.  It is what is after the accounts/    .  It works this way for all coins.  You can see my account ID for Bitcoin Cash below.  9e1030...... all of that is the ID.
