How to check payment in Blockchain info wallet

Question

I am using Blockchain API v2 and i am trying to create bill for payment and send to my customer via telegram bot. Following is the code:

xpub='***'
keyk='02e57f1***'
url='https://api.blockchain.info/v2/receive?xpub='+str(xpub)+'&callback=https%3A%2F%2Fdoors03.ru&key='+keyk
x=requests.get(url)
r=x.json()
r=r['address']

When I am checking if the payment was received to the above address using this:

data={ "Content-Type": "text/plain","key":keyk,"addr":r,"callback":"https%3A%2F%2Fdoors03.ru","onNotification":"KEEP", "op":"RECEIVE"}
r = requests.post(url, data=data)

I get this error: {\n "message" : "Internal handlers error"\n}

Kindly help me wherever I am going wrong.

Answer 1

The above error is probably occurring due to wrong interpretation of their API.

as post parameters, like in other methods they have provided in API. In those methods parameters are URL encoded like you did with callback link. The main reason of your error may be that you put "Content-Type: text/plain" in data object, and maybe encoded callback URL.
