Start here:
https://developer.intuit.com/
Follow the docs (https://developer.intuit.com/docs/0100_accounting) and implement OAuth to connect to QuickBooks Online.
Create customers by HTTP POSTing a JSON request to QuickBooks Online:
https://developer.intuit.com/docs/api/accounting/Customer
The JSON request will look something like this:
{
"BillAddr": {
"Line1": "123 Main Street",
"City": "Mountain View",
"Country": "USA",
"CountrySubDivisionCode": "CA",
"PostalCode": "94042"
},
"Notes": "Here are other details.",
"Title": "Mr",
"GivenName": "James",
"MiddleName": "B",
"FamilyName": "King",
"Suffix": "Jr",
"FullyQualifiedName": "King Groceries",
"CompanyName": "King Groceries",
"DisplayName": "King's Groceries",
"PrimaryPhone": {
"FreeFormNumber": "[phone]"
},
"PrimaryEmailAddr": {
"Address": "jdrew#myemail.com"
}
}
You'll get back something like this:
{
"Customer": {
"Taxable": true,
"BillAddr": {
"Id": "112",
"Line1": "123 Main Street",
"City": "Mountain View",
"Country": "USA",
"CountrySubDivisionCode": "CA",
"PostalCode": "94042"
},
"Notes": "Here are other details.",
"Job": false,
"BillWithParent": false,
"Balance": 0,
"BalanceWithJobs": 0,
"CurrencyRef": {
"value": "USD",
"name": "United States Dollar"
},
"PreferredDeliveryMethod": "Print",
"domain": "QBO",
"sparse": false,
"Id": "67",
"SyncToken": "0",
"MetaData": {
"CreateTime": "2015-07-23T10:58:12-07:00",
"LastUpdatedTime": "2015-07-23T10:58:12-07:00"
},
"Title": "Mr",
"GivenName": "James",
"MiddleName": "B",
"FamilyName": "King",
"Suffix": "Jr",
"FullyQualifiedName": "King's Groceries",
"CompanyName": "King Groceries",
"DisplayName": "King's Groceries",
"PrintOnCheckName": "King Groceries",
"Active": true,
"PrimaryPhone": {
"FreeFormNumber": "[phone]"
},
"PrimaryEmailAddr": {
"Address": "jdrew#myemail.com"
},
"DefaultTaxCodeRef": {
"value": "2"
}
},
"time": "2015-07-23T10:58:12.099-07:00"
}
Make sure you save that Id attribute, you'll need that later.
The process for creating Items is similar. Docs:
https://developer.intuit.com/docs/api/accounting/Item
Everything is just standard OAuth requests. Go grab an OAuth library for Rails and you should be all set.
