Deposit Funds to Coinbase Using Sign In with Coinbase API

Note: I have not tested any of this. This is offered without any guarantee. When I have additional time after the January 12, 2024, I will test this further. Until then, it is meant as a sketch of a solution.

Basic Procedure

The basic process is as follows:

1. Know the API key and the secret key. You can use the same Api Keys and Secret Keys as accounts that are generated when logged into your Coinbase acount under "Settings >> API". Make sure that the following permissions are granted:

• wallet:accounts:read
• wallet:deposits:create
• wallet:deposits:read
• wallet:payment-methods:read

Make sure that proper care is taken to safeguard the secret key.

2. Get payment account information (it is assumed that this has already been added to Coinbase).

3. Get account information of the account into which you wish to deposit funds.

4. Submit Funds Transfer

List Accounts

It is assumed that API key and the secret key is known. Add them in the place of "" below.

Make sure that you have access to wallet:accounts:read in for the api key for which you are seeking to access data.

api_key <- rstudioapi::askForPassword(prompt = "Please Provide API Key")
secret_key <- rstudioapi::askForPassword(prompt = "Please Provide API Secret Key")

list_accounts_var <- interact_SWCB_API_keys(api_key = api_key,
                                            secret_key = secret_key,
                                            method = "GET",
                                            reqPath = "accounts")

Here we need to extract the information from the variable list_variable_var$data and choose the index n that corresponds to the account into which you wish to deposit. The proper account will need to be identified if there is more than one. The variable will be list_accounts_var$data[[n]]$id, where n is a number that must be assigned or substituted into this expression.

Get Payment Methods

api_key <- rstudioapi::askForPassword(prompt = "Please Provide API Key")
secret_key <- rstudioapi::askForPassword(prompt = "Please Provide API Secret Key")

list_payment_methods_var <- interact_SWCB_API_keys(api_key = api_key,
                                            secret_key = secret_key,
                                            method = "GET",
                                            reqPath = "payment-methods")

list_payment_methods_var

Once again, you will receive a list of possible payment methods. I am unable to access the API right now, so I will need to examine the format more in terms of how to extract the information. But the id for all the payment methods should in principle be included in this list_payment_methods_var$data Again, once the proper index n for the payment method is identified, the id can be found at list_payment_methods_var[[n]]$id

Deposit

Hopefully, you should have the Payment Methods id from which you wish to deposit and the Account id into which you wish to deposit. With this, you should be ready to deposit.

Using the above API and secret keys, something like the following code should permit the deposit an amount of $10 in USD to an account to be specified.

amount <- "10"
currency <- "USD"
#Use payment method id from above for account into which deposit was desired.
payment_method <- list_payment_methods_var$data[[n]]$id.
#Use account id from above for account into which deposit was desired.
account_deposit_id <- list_accounts_var$data[[n]]$id 

payload <- paste0('{\"amount\":\"',amount,'\",\"currency\":\"',currency,'\",\"payment_method\":\"',payment_method,'\"}')

rsiwcbapi::interact_SWCB_API_keys(api_key = api_key,
                                  secret_key = secret_key,
                                  method = "POST",
                                  reqPath = paste0("accounts/",
                                                   account_deposit_id,"/deposits"),
                                  body = payload)

I have tested this code. All the same it is offered without any guarantee or promise of suitability for any given purpose.
