Catenis API Client for WordPress

Catenis API Client for WordPress enables (JavaScript) code on WordPress pages to interact with the Catenis API. Enabling the Catenis API client To enable the Catenis API client for a given WordPress page, go to the page's edit page and look for a section (meta box) named "Catenis API Client" below the page's main editing panel. Make sure the section is expanded, and check the Load Catenis API Client checkbox. You can then choose to override the global settings used for instantiating the Catenis API client on that given page, like using a different device ID and its associated API access secret. Otherwise, whatever is configured in the plugin's global settings -- configured under "Settings" | "Catenis API Client" -- is going to be used. Using the Catenis API client Once enabled, a global JavaScript variable named ctnApiClient is made available on the page. That variable holds the instantiated Catenis API client object. Use the ctnApiClient variable to call the Catenis API methods by invoking the corresponding method on that object. For a reference of the available methods, please refer to the Catenis API JavaScript Client as it is functionally identical to the Catenis API Client for WordPress, except for notifications support and error handling. Notifications support The notification feature on Catenis API Client for WordPress is almost identical to the one found on the Catenis API JavaScript client. The two noticeable differences are:

1. The Catenis API client object can emit a comm-error event.
2. The open event emitted by the WebSocket notification channel object may return an error.

Please refer to the "Receiving Notifications" section below for detailed information on how to receive Catenis notifications from within WordPress pages. Error handling Errors that take place while calling the Catenis API methods are returned as standard JavaScript Error objects.

System requirements The PHP executable should be in the system PATH so that the plugin can spawn the process used to handle notifications. Installation procedure

1. Upload the plugin files to the "/wp-content/plugins/" directory.
2. Activate the plugin through the "Plugins" menu in WordPress.
3. Go to "Settings" | "Catenis API Client" to configure the global settings for instantiating the Catenis API client.
4. A meta box named "Catenis API Client" will be available on every WordPress page's edit page. Use it to make the Catenis API client available from a given page, and optionally configure custom settings for instantiating the Catenis API client for that given page.

Please refer to Catenis API documentation for further information on accessing the Catenis API.

4.0.0

• Added support for changes introduced by version 0.12 of the Catenis API: new non-fungible assets feature, including the new API methods Issue Non-Fungible Asset, Reissue Non-Fungible Asset, Retrieve Non-Fungible Asset Issuance Progress, Retrieve Non-Fungible Token, Retrieve Non-Fungible Token Retrieval Progress, Transfer Non-Fungible Token, and Retrieve Non-Fungible Token Transfer Progress.
• The issuance event entries returned by the retrieveAssetIssuanceHistory method for non-fungible assets are different from the ones returned for regular (fungible) assets as per the new behavior of version 0.12 of the Catenis API. The observed differences are: the amount key is replaced by a new nfTokenIds key, which lists the IDs of the non-fungible tokens that have been issued; and the holdingDevice key is replaced by a new holdingDevices key, which lists the Catenis virtual devices to which the issued non-fungible tokens have been assigned.

3.0.0

• Added support for changes introduced by version 0.11 of the Catenis API: new asset export feature, including the new API methods Export Asset, Migrate Asset, Asset Export Outcome, Asset Migration Outcome, List Exported Assets, and List Asset Migrations.
• The list of current asset holders returned by the listAssetHolders method may now include an entry that reports the total asset amount that is currently migrated to foreign blockchains as per the new behavior of version 0.11 of the Catenis API. That entry differs from the regular ones in that the holder property is missing and a new boolean type property named migrated, the value of which is always true, is present.
