How to properly verify that payment was made to specific address with known sum, using txid and blockchain.info API

Use case: User A sent 0.001 BTC to User B. I should verify that user B really received that amount to specific address.

For example, we have transaction id feec67bb56dbb5d18c535645879ec65c1d9b2da63e512c89d0ca052f40c4cfc9 .
We should verify that payment was made in amount of 5000000 satoshi to address 1C5MT6YVpZF3G6xhp6PFti1ySzAxtpNf86 .

I make request to https://blockchain.info/tx/feec67bb56dbb5d18c535645879ec65c1d9b2da63e512c89d0ca052f40c4cfc9?format=json

)

Then look into out array and find our address and its amount - thats enough for verifying ? BTW where I can see number of confirmations of this transaction?

How about this?

Code:

Code:

5000000
