Updating Documentation for New Developer Console

Account provisioning for Google Apps

Account provisioning for Google Apps is an open source API to:

Generate available usernames in your Google Apps domain
Create Google Apps accounts in your domain

It can be used in a website where users create their own accounts...

|

a script that creates accounts in bulk...

|

or via a CSV input...

|

Usernames are generated automatically via configurable patterns. Sample images are taken from the included demos. Give them a try here!

This API can be installed as a RESTful service (to be invoked from almost any programming language and platform) or as a Java library.

Who should use it

Google Apps deployments where new usernames need to be created. Deployments that need to sync existing usernames can use [Google Apps Directory Sync] (https://support.google.com/a/answer/106368?hl=en) or [Google Apps School Directory Sync] (https://support.google.com/a/answer/6027781?hl=en).

Why you should use it

Username cache: It caches all your Google Apps accounts, which makes it fast (minimum calls to Google servers) and less likely to hit [Directory API calls/day limits] (https://developers.google.com/admin-sdk/directory/v1/limits)
Custom user fields: Usernames are generated from the user's first name, last name and a set of (optional) custom fields, i.e. second last name, student ID, department, nickname, etc.
Locked suggestions: Suggested usernames will remain locked (unavailable to other users) until they expire or are explicitly unlocked.
Backed by Google Apps Admin SDK: Uses the Google Apps [AdminSDK Directory API] (https://developers.google.com/admin-sdk/directory/)
SSL support: All REST calls can be encrypted using SSL
Any programming language: You can choose any programming language and platform that supports REST calls. Almost any language and platform do.

What methods does this API offer

suggest: returns a list of username suggestions based on first name, last name and a set of custom fields.
create: creates a Google Apps account.
select: unlocks username suggestions that will no longer be used.

See the API Overview section to learn more about how to invoke these methods.

Quick start

Ready? Try the demos!

This API needs Java, but don't worry you don't need to develop your client in Java. You can use any language and platform you like (Python, JavaScript, PHP, C#, ObjectiveC, Go, etc.) as long as it can do REST calls.

Included demos are built in JavaScript.

1. Check your Java version

In the terminal run:

java -version

If you see: java version "1.7.X" or a newer version you are ready to go. If not, install Java 7 or a newer verion.

2. Set your Google Apps domain configuration

Follow the steps in the Google Apps domain configuration guide to configure your domain to work with this API.

3. Start the RESTful API service

Move the config.properties and the p12 file (created in the previoius step) to the bin/ folder.

In the terminal, run:

java -jar appsProvisioning-0.0.1.jar -rest -port 8080

This will start the RESTful API service on port 8080. If you already have a server running on port 8080, change it to another port, e.g. 8888.

4. Open a demo

Awesome! You can now start getting usernames suggestions and creating Google Apps accounts in your domain.

See the Note below if you used a different port from 8080

Open any of the index.html demos under the demos/ folder:

Demo	Sample
self-provisioning-demo Each user selects and creates their own account
bulk-provisioning-demo All accounts are created in bulk
csv-provisioning-demo All accounts are created in bulk from a CSV input

Note: If you used a different port from 8080, open first the JavaScript .js file inside the demo folder and update

var API_HOST = 'http://localhost:8080';

to point to the right port. For example:

var API_HOST = 'http://localhost:8888';

Both demos will initially show the configuration parameters that are relevant to the client. For example:

This screen will disappear after a couple of seconds.

You can change these parameters in the config.properties file and use this screen to verify the current configuration. Follow the next step to see how.

A quick way of testing your server is by invoking the suggest method via the GET service <a href="http://localhost:8080/rest/suggest?firstname=john&lastname=smith"target="_blank">http://localhost:8080/rest/suggest?firstname=john&lastname=smith

5. Play with the configuration

Now that you have the demos up and running is a great time to learn how usernames are generated.

Open the config.properties file and look for the accounts.UsernameGeneration.patterns property.
Replace its value with the following one:

accounts.UsernameGeneration.patterns=[C1_firstname].[lastname][custom1],[C3_lastname]_[custom1],[C1_custom1][firstname],[firstname][C1_lastname]_[custom1],[lastname][custom1]

Now kill the Java process (Ctrl+C or Cmd+C) in the terminal and start the RESTful API service again (step 3). This will load the new patterns configuration, which will result in different usernames being generated.

Open the self-provisioning-demo\index.html demo and notice how the generated usernames are now different. They now follow the new patterns set in the config file. The configuration section explains how to patterns work.

Next, you can try changing other accounts.UsernameGeneration properties. For example, updating the following properties:

accounts.UsernameGeneration.numberOfSuggestions=5

accounts.UsernameGeneration.suggestedUsernamesTimeout=10

This will result in:

5 usernames being suggested (instead of 3)
usernames will expire after 10 seconds (instead of in 2 minutes)

System overview

This API is developed in Java and can be invoked from any language and platform that can do REST API calls. The username cache is an H2 database, so you will see a usernames(*).mv.db file when running the API.

Only usernames are cached, no names or other user's data is ever stored. The H2 Console Application can be used to inspect the cache.

The cache can be disabled with the cachedUsernames property. When disabled it will do Admin SDK API calls. When enabled, the cache will refresh periodically (see the cacheExpirationHours property).

API overview and sample code

`suggest` method

Description: Method that suggests available usernames in a domain. Uses the configuration file (see configuration) to determine:

API limits

Account provisioning for Google Apps follows the same [AdminSDK Directory API limits] (https://developers.google.com/admin-sdk/directory/v1/limits). Each call to create, select and suggest consumes a different number of Directory API calls:

create: 1 API call
select: 0 API calls
suggest:
cache enabled (cachedUsernames=YES): 0 API calls
cache disabled (cachedUsernames=NO): number of API calls is equal or larger than the numberOfSuggestions property

Configuration properties

The configuration is set in the config.properties file. Configuration properties are divided in four categories:

Username generation properties: use the property prefix accounts.UsernameGeneration.
Google API properties: use the property prefix apis.GoogleAPIs.
Cache location properties: use the property prefix db.h2.
SSL properties: use the property prefix security.ssl.

Username generation properties

`accounts.UsernameGeneration.cachedUsernames`

Description: A username cache can be used to check if a username already exists. This prevents reaching AdminSDK API calls/day limit. If cachedUsernames is set to YES username availability will be checked against the cache. If set to NO it will be checked against the Google Directory (using a Directory API call).

Possible values: YES and NO

`accounts.UsernameGeneration.cacheExpirationHours`

Description: Defines the expiration time in hours of the usernames cache. After expiration, the application refreshes the username cache. For reference, refreshing an account with 1 million users takes approximately 35 minutes.

Possible values: Integers larger or equal to 1

Default: 24

`accounts.UsernameGeneration.numberOfSuggestions`

Description: The number of username suggestions to be returned for each call to suggest.

Possible values: Integer between 1 and 10 (inclusive)

Default: 3

`accounts.UsernameGeneration.suggestedUsernamesTimeout`

Description: The amount of time (in seconds) that suggested usernames will remain locked (unavailable to another client).

Possible values: Integer greater than 0.

Default: 120 (2 minutes)

`accounts.UsernameGeneration.patterns`

Description: A pattern is something that looks like [firstname][lastname]. This pattern indicates the API that we want to generate a username with "the firstname followed by the lastname". Now, if that username happens to be taken the API will need another pattern. Therefore, a list of multiple patterns is recommended. For example:

accounts.UsernameGeneration.patterns=[firstname][lastname],[lastname][firstname]

This will first try to generate a username with "the firstname followed by the lastname" if that is taken then it will try to generate a username with "the lastname followed by the firstname".

So far so good?

Great. Now, say we want to generate a username with "the nickname followed by the lastname" of a person. We'd simply do:

accounts.UsernameGeneration.patterns=[nickname][lastname]

What's [nickname] you might ask?

Well, nickname is a field that should be passed to the suggest method. For example:

var parameters = '{' +
    '"firstname": "Jonathan",' +
    '"lastname": "Bravo",' +
    '"nickname": "Jonny"' +
'}';

This will generate the username jonnybravo.

NOTE:

It is not mandatory to pass nickname (or any custom field) for all users. If nickname is not provided for a user the API will skip that pattern and move on to the next one.
firstname and lastname are mandatory. Even if the pattern doesn't make use of them.

Taking the first char(acters) of a field

Now say that for someone named John Smith we'd like to generate a username jsmith. We'd do it with the following pattern:

[C1_firstname][lastname]

C1 indicates that the API should take the first character of firstname. If we'd like to take the first two characters then we'd do:

[C2_firstname][lastname]

This same method applies for custom fields. For example, if we wanted to split the first character of the nickname we'd do:

[C1_nickname]

Adding a counter to a pattern

Now, say we have so many people named "John Smith" in a school district that we ran out of patterns. We could then define a pattern that adds a number at the end of the username:

[firstname][lastname][#]

[#] indicates that a number will be added to the username. For example: johnsmith3. This numeric value will start at 1 and continue adding until a username is available.

Note: The use of [#] should be the last resort as this counter can become hard to remember, e.g. johnsmith3816. A list of multiple patterns without [#] is encouraged before using a pattern with [#].

Adding separators to usernames

A common practice is to separate usernames with a period (.), an underscore (_) or a dash (-). These separators can be added to patterns. Example:

[firstname].[lastname]

would generate the username john.smith

Adding a string to a pattern

Same as the separators, it is possible to add a static string to username suggestions. For example, the pattern:

[lastname]_nyc

would generate the username smith_nyc

What if the API runs out of patterns?

The following pattern is used as the last resort:

[C9_firstname][C9_lastname][#]

`patterns` example

Given the following user data map, customFields and patterns: ```json { "firstname": "Carlos", "lastname": "Álvarez", "region": "CA", "group": "5A" } ```

patterns = [firstname].[lastname], [C1_firstname].[lastname], [firstname][lastname]_[region], [firstname][lastname]_[group], [lastname]_nyc, [firstname][lastname][#]

Then consecutive calls to the suggest method will return (in that order):

Generated username	Used pattern
carlos.alvarez	`[firstname].[lastname]`
c.alvarez	`[C1_firstname].[lastname]`
carlosalvarez_mx	`[firstname][lastname]_[region]`
carlosalvarez_5A	`[firstname][lastname]_[group]`
alvarez_nyc	`[lastname]_nyc`
carlosalvarez1	`[firstname][lastname][#]`
carlosalvarez2	`[firstname][lastname][#]`
carlosalvarez3	`[firstname][lastname][#]`
...	`[firstname][lastname][#]`

Notes:

Special characters (e.g accents) are removed
All text gets converted to lowercase
Using a [#] will ignore the following patterns (as it will continue increasing the counter)
