blockcypher.com API PHP - Not receiving any POST variables on callback

[icanscript]

Hi, (Not sure if this is correct section)

I have been working for someone to create a payment gateway using BlockCypher. Everything seems to work well.... apart from receiving anything on the callback.

I can see the callback happening, But I have not received any GET or POST variables from the callback. Such as TXid, Input Address, Value.

Has anyone experienced a similar issue before? or even used this provider?

Thanks in advance

Hey there, co-founder and CTO of BlockCypher here.

Can you clarify what you mean by GET or POST variables? Callbacks are done using POST requests and the details of the payments are in the body of the POST as a JSON document, not as URL parameters if that's what you were expecting.

Could you or anyone can post here how the problem was solved. The callback response is only providing me some garbage value. Moreover, is it possible to have success response only after a certain number of confirmation?

Not sure what exactly was the issue described above but I'm guessing it was related to decoding the JSON body. The full transaction is sent in the POST body as JSON, make sure you decode that properly with the programming language you're using (for ex in PHP check http://stackoverflow.com/questions/8945879/how-to-get-body-of-a-post-in-php).

Once you can decode the full transaction, the number of confirmations is a property there.

I tested with this...

http://blockcypher.github.io/php-client/sample/doc/payment-api/CreateForwardingAddress.html

When payment is made to the created address, it is getting forwarded with a success callback like...

Code:

Results: Array
(
)


Results: Array
(
    [uniqid] => 54321abcde
)

sample data used

Once callback URL, which contains the following code, is called with this Unique ID...

http://blockcypher.github.io/php-client/sample/doc/payment-api/GetForwardingAddress.html

I am getting the following result...

Code:

Results: Array
(
)


Results: Array
(
    [uniqid] => 54321abcde
    [__utma] => 12.34.56.78.90.12
    [fc] => {"abcd":"1:1234"}
    [pv] => {"d":"1:5432"}
    [__cfduid] => abcde54321
    [_ga] => GA1.2.34.56
    [__utmz] => 98.76.54.32.utmcsr=example.com|utmccn=(referral)|utmcmd=referral|utmcct=/example/
)

Now, how do I decipher the above data?

Does anyone know how to stop blockcypher callback for every single confirmation after a payment is made through the payment forwarding API with enable_confirmations = true ?

[mriou]

Do you want the callbacks to stop at some point or just have a lower number of confirmations than 6? For the latter you can just set enable_confirmations=false and create a webhook yourself with the desired confirmation count.

code an if statement to only complete whatever action after x amount of confirmations.

I want the callbacks to stop at some point. Will it stop at 6 automatically ?

I'd also like to know the difference between [n_tx] & [final_n_tx] ?
