# Migrating from OAuth 1.0 to OAuth 2.0

## Automatic migration (auto-migrate existing OAuth 1.0 tokens to OAuth 2.0 tokens)

@todo

## Manual migration (have people re-connect manually to get OAuth 2.0 tokens)

0. Make a backup of your code
0. Make a backup of your existing OAuth v1.0 tokens
0. `git clone` the repository to get the new code
0. Make code changes as detailed below
0. Go get your `Client ID` and `Client Secret` from `developer.intuit.com` for your app

## Code change - IntuitAnywhere constructor

This constructor for the `QuickBooks_IPP_IntuitAnywhere` class has changed.

Anywhere you see this:

```
new QuickBooks_IPP_IntuitAnywhere($dsn, $encryption_key, $oauth_consumer_key, $oauth_consumer_secret, $quickbooks_oauth_url, $quickbooks_success_url);
```

Needs to change to this (note the new parameters):

```
new QuickBooks_IPP_IntuitAnywhere(QuickBooks_IPP_IntuitAnywhere::OAUTH_V2, $sandbox, $scope, $dsn, $encryption_key, $oauth_client_id, $oauth_client_secret, $quickbooks_oauth_url, $quickbooks_success_url);
```

`$scope` can be 'com.intuit.quickbooks.accounting', 'com.intuit.quickbooks.payment', or 'com.intuit.quickbooks.accounting com.intuit.quickbooks.payment' for access to both.

## Database changes

```
ALTER TABLE `quickbooks_oauth`
RENAME TO `quickbooks_oauthv1`;
```

```
ALTER TABLE `quickbooks_oauthv1`
CHANGE `quickbooks_oauth_id` `quickbooks_oauthv1_id` int(10) unsigned NOT NULL AUTO_INCREMENT FIRST;
```

```
CREATE TABLE `quickbooks_oauthv2` (
  `quickbooks_oauthv2_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `app_tenant` varchar(255) NOT NULL,
  `oauth_state` varchar(255) DEFAULT NULL,
  `oauth_access_token` text,
  `oauth_refresh_token` text,
  `oauth_access_expiry` datetime DEFAULT NULL,
  `oauth_refresh_expiry` datetime DEFAULT NULL,
  `qb_realm` varchar(32) DEFAULT NULL,
  `request_datetime` datetime NOT NULL,
  `access_datetime` datetime DEFAULT NULL,
  `last_access_datetime` datetime DEFAULT NULL,
  `last_refresh_datetime` datetime DEFAULT NULL,
  `touch_datetime` datetime DEFAULT NULL,
  PRIMARY KEY (`quickbooks_oauthv2_id`)
);
```

## Code change - IntuitAnywhere->load(...)

The `->load(...)` method has changed, dropping the `$the_username` parameter. Where you see this:

```
$creds = $IntuitAnywhere->load($the_username, $the_tenant);
```

Change it to this:

 ```
$creds = $IntuitAnywhere->load($the_tenant);
```

## Code change - IntuitAnywhere->check(...)

The `->check(...)` method has changed, dropping the `$the_username` parameter. Change:

```
if ($IntuitAnywhere->check($the_username, $the_tenant)
```

To this:

```
if ($IntuitAnywhere->check($the_tenant)
```

## Code change - IntuitAnywhere->test(...)

The `->test(...)` method has changed, dropping the `$the_username` parameter. Change:

```
$IntuitAnywhere->test($the_username, $the_tenant))
```

To this:

```
$IntuitAnywhere->test($the_tenant))
```

## Code change - IntuitAnywhere->handle(...)

The `->handle(...)` method has changed, dropping the `$the_username` parameter. Change:

```
$IntuitAnywhere->handle($the_username, $the_tenant))
```

To this:

```
$IntuitAnywhere->handle($the_tenant))
```

## Code change - IntuitAnywhere->expiry(...), IntuitAnywhere->reconnect(...), IntuitAnywhere->disconnect(...)

Calls to the `->expiry(...)`, `->reconnect(...)`, and `->disconnect(...)` methods are no longer necessary. OAuthV2 token refreshes are done automatically before every API call if the time-to-live of the Access Token is less than 60 seconds. Also, calls to these methods will fail, as they call the old `->oauthLoad(...)` method, which no longer exists in the drivers (it has been updated to `->oauthLoadV1(...)` and `->oauthLoadV2(...)`). See #269 and #271 for discussion.

## Code change - IPP->authMode(...)

The parameters to the `->authMode(...)` method have changed. Change:

```
$IPP->authMode(
    QuickBooks_IPP::AUTHMODE_OAUTH,
    $creds);
```

To this:

```
$IPP->authMode(
    QuickBooks_IPP::AUTHMODE_OAUTHV2,
    $creds);
```

## Code change - QuickBooks_IPP(...) constructor

The `QuickBooks_IPP(...)` constructor needs an additional parameter. Change this:

```
// Set up the IPP instance
$IPP = new QuickBooks_IPP($dsn);
```

To this:

```
// Set up the IPP instance
$IPP = new QuickBooks_IPP($dsn, $encryption_key);
```

## Reconnect

1. Disconnect from QuickBooks (or clear your token from the `quickbooks_oauthv1` SQL table).
1. Reconnect to QuickBooks (you should see a slightly different OAuth process, and see entries appear in the `quickbooks_oauthv2` SQL table).
