Token generator

An admin tool provides a web service for generating Moodle web service tokens. It conceptually works the same way as /login/token.php, but via web services. See https://docs.moodle.org/dev/Creating_a_web_service_client#How_to_get_a_user_token

Branches

The following maps the plugin version to use depending on your Moodle version.

Installation

Add the plugin to /admin/tool/token/

Run the Moodle upgrade.

Configuration

The plugin has following settings.

• Token lifetime - allows configuring max lifetime for the generated tokens. Once generated tokens will be valid for configured time.
• Enabled auth methods - allows configuring auth methods to filter user by. Token can be generated for users with enabled auth methods only.
• Enabled user fields - allows configuring user fields for matching users, including unique custom user profile fields. These fields could be used in a web service call to match users in Moodle. Note: 'id' filed is always enabled.
• Enabled services - allows whitelisting only specific services for generating tokens using this plugin. Token can be generated for enabled services only.

Usage

You need to configure your Moodle for using Web services. See documentation https://docs.moodle.org/310/en/Web_services

On the installation the plugin will automatically create Token Generator Service, but it will be disabled by default. You should enable it and create a token for that service. Then you can call tool_token_get_token function baked to that service.
