How to check confirmations number programmatically How can I check confirmations number for some bitcoin address programmatically? (I have eCommerce shop where each order has separate address).
I want to use blockchain.info API.

Here is an example of the API call, but I can't figure out what numbers should I check in API response:

Confirmations for an address aren't really a thing.  Addresses are not confirmed; transactions are.  A single address is typically used in multiple transactions: one where the address is used as an output, and one where the first transaction was used as an input.  Although it's not a best practice, addresses can even be re-used multiple times.

It looks like this particular address has been used in two different transactions.  Once as an output in 00c83c7677d414053488d0b51067feee157a5b82d5acec5bfe8e9c540c11c624, and once as in input in 378f829160cb9c99cc7a8fb1152472b80f0e1ea9c9cc24118dbccc2da72dedcf.

Each of these two transactions returned in the API response has a block_height value (489353 and 489355).  That is the block at which the transaction was included.  To find how many confirmations each transaction has, subtract the block_height by the height of the most recently confirmed block, and add 1.  So if the current block is 489355, one transaction has 1 confirmation, and the other has 3.
