Confluence

You can use the Confluence connector to perform insert, delete, update, and read operations on Confluence.

Before you begin

Before using the Confluence connector, do the following tasks:

• In your Google Cloud project:
  • Ensure that network connectivity is set up. For information about network patterns, see Network connectivity.
  • Grant the roles/connectors.admin IAM role to the user configuring the connector.
  • Grant the following IAM roles to the service account that you want to use for the connector:
    • roles/secretmanager.viewer
    • roles/secretmanager.secretAccessor

    A service account is a special type of Google account intended to represent a non-human user that needs to authenticate and be authorized to access data in Google APIs. If you don't have a service account, you must create a service account. For more information, see Creating a service account.

  • Enable the following services:
    • secretmanager.googleapis.com (Secret Manager API)
    • connectors.googleapis.com (Connectors API)

    To understand how to enable services, see Enabling services.

  If these services or permissions have not been enabled for your project previously, you are prompted to enable them when configuring the connector.

Configure the connector

Configuring the connector requires you to create a connection to your data source (backend system). A connection is specific to a data source. It means that if you have many data sources, you must create a separate connection for each data source. To create a connection, do the following steps:

1. In the Cloud console, go to the Integration Connectors > Connections page and then select or create a Google Cloud project.

   Go to the Connections page

2. Click + CREATE NEW to open the Create Connection page.
3. In the Location section, choose the location for the connection.
   1. Region: Select a location from the drop-down list.

      For the list of all the supported regions, see Locations.

   2. Click NEXT.
4. In the Connection Details section, complete the following:
   1. Connector: Select Confluence from the drop down list of available Connectors.
   2. Connector version: Select the Connector version from the drop down list of available versions.
   3. In the Connection Name field, enter a name for the Connection instance.

      Connection names must meet the following criteria:

      • Connection names can use letters, numbers, or hyphens.
      • Letters must be lower-case.
      • Connection names must begin with a letter and end with a letter or number.
      • Connection names cannot exceed 49 characters.
   4. Optionally, enter a Description for the connection instance.
   5. Optionally, enable Cloud logging, and then select a log level. By default, the log level is set to Error.
   6. Service Account: Select a service account that has the required roles.
   7. Optionally, select Include Archived Spaces to include content from archived spaces in the result. The default is false.
   8. Optionally, enter a Space Key for search to display contents only from this specific space.
   9. Optionally, configure the Connection node settings:
      • Minimum number of nodes: Enter the minimum number of connection nodes.
      • Maximum number of nodes: Enter the maximum number of connection nodes.

      A node is a unit (or replica) of a connection that processes transactions. More nodes are required to process more transactions for a connection and conversely, fewer nodes are required to process fewer transactions. To understand how the nodes affect your connector pricing, see Pricing for connection nodes. If you don't enter any values, by default the minimum nodes are set to 2 (for better availability) and the maximum nodes are set to 50.

   Note: You can customize the connection node values only if you are a Pay-as-you-go customer.
   10. Optionally, click + ADD LABEL to add a label to the Connection in the form of a key/value pair.
   11. Click NEXT.
5. In the Destinations section, enter details of the remote host (backend system) you want to connect to.
   1. Destination Type: Select a Destination Type.
      • Select Host address from the list to specify the hostname or IP address of the destination.
      • If you want to establish a private connection to your backend systems, select Endpoint attachment from the list, and then select the required endpoint attachment from the Endpoint Attachment list.
        Note: To understand how to create an endpoint attachment, see PSC service attachment and endpoint attachment. After you have created the endpoint attachment, it will be visible in the Endpoint Attachment list.

      If you want to establish a public connection to your backend systems with additional security, you can consider configuring static outbound IP addresses for your connections, and then configure your firewall rules to allowlist only the specific static IP addresses.

      To enter additional destinations, click +ADD DESTINATION.

   2. Click NEXT.
6. In the Authentication section, enter the authentication details.
   1. Select an Authentication type and enter the relevant details.

      The following authentication types are supported by the Confluence connector:

      • Basic
      • APIToken
      • OAuth2.0

   To understand how to configure these authentication types, see Configure authentication.

   2. Click NEXT.
7. Review: Review your connection and authentication details.
8. Click Create.

Configure authentication

Enter the details based on the authentication you want to use.

• Basic
  • Username: The Confluence user account used to authenticate.
  • Password: The password associated with the account.
• APIToken
  • Username: The Confluence username used to create the API token.
  • API Token: The password for the username is an API token. Select the Secret Manager Secret containing the API Token associated with the Confluence username.
• OAuth 2.0 - Authorization code
  • Client ID: Client ID as provided by your external application.
  • Scopes: Permission scopes. The offline_access scope must be used with the Confluence connector. For more information about Confluene scopes, see Confluence Scopes.
  • Client secret: Select the Secret Manager secret. You should have created the Secret Manager secret prior configuring this authorization.
  • Secret version: Secret Manager secret version for client secret.

  For the Authorization code authentication type, after creating the connection, you must perform a few additional steps for configuring authentication. For more information, see Additional steps after connection creation.

  Note: If you are using Authorization code authentication type and have made any cofiguration changes in your Confluence application, you must re-authorize your Confluence connection. To understand how to re-authorize, see Re-authorization for Authorization code.

Additional steps after connection creation

If you selected OAuth 2.0 - Authorization code for authentication, you must do the following additional steps after creating the connection:

1. In the Connections page, locate the newly created connection.

   Notice that the Status for the new connector will be Authorization required.

2. Click Authorization required.

   This shows the Edit authorization pane.

3. Copy the Redirect URI value to your external application.
4. Verify the authorization details.
5. Click Authorize.

   If the authorization is successful, the connection status will be set to Active in the Connections page.

Re-authorization for authorization code

If you are using Authorization code authentication type and have made any cofiguration changes in your Confluence application, you must re-authorize your Confluence connection. To re-authorize a connection, perform the following steps:

1. Click on the required connection in the Connections page.

   This opens the connection details page.

2. Click Edit to edit the connection details.
3. Verify the OAuth 2.0 - Authorization code details in the Authentication section.

   If required, make the necessary changes.

4. Click Save. This takes you to the connection details page.
5. Click Edit authorization in the Authentication section. This shows the Authorize pane.
6. Click Authorize.

   If the authorization is successful, the connection status will be set to Active in the Connections page.

System limitations

The Confluence connector can process 28 transaction per second, per node, and throttles any transactions beyond this limit. By default, Integration Connectors allocates 2 nodes (for better availability) for a connection.

For information on the limits applicable to Integration Connectors, see Limits.

Note: The number of Integration Connectors nodes will autoscale dynamically based on your usage. However, if you want to reserve capacity for large volumes without waiting for autoscaling, you can adjust the minimum node value for a connection. More nodes are required to process more transactions for a connection. Conversely, fewer nodes are required if a connection processes fewer transactions. To configure the node values, do the following:

• If you are a pay-as-you-go customer, configure the minimum and maximum node value in the edit connection page.
• If you are a subscription based customer, contact support.

The maximum transactions that a node can handle depends on various factors. So, before adjusting the minimum nodes for better throughput, it is recommended you check if your backend systems are set up optimally to handle the required traffic.

Use the Confluence connection in an integration

After you create the connection, it becomes available in both Apigee Integration and Application Integration. You can use the connection in an integration through the Connectors task.

• To understand how to create and use the Connectors task in Apigee Integration, see Connectors task.
• To understand how to create and use the Connectors task in Application Integration, see Connectors task.

Entities, operations, and actions

All the Integration Connectors provide a layer of abstraction for the objects of the connected application. You can access an application's objects only through this abstraction. The abstraction is exposed to you as entities, operations, and actions.

Note: You can view the entities, operations, and actions of a connector in the Connectors task.

• Entity: An entity can be thought of as an object, or a collection of properties, in the connected application or service. The definition of an entity differs from a connector to a connector. For example, in a database connector, tables are the entities, in a file server connector, folders are the entities, and in a messaging system connector, queues are the entities.

  However, it is possible that a connector doesn't support or have any entities, in which case the Entities list will be empty.

• Operation: An operation is the activity that you can perform on an entity. You can perform any of the following operations on an entity:
  • List
  • Get
  • Create
  • Update
  • Delete

  Selecting an entity from the available list, generates a list of operations available for the entity. For a detailed description of the operations, see the Connectors task's entity operations. However, if a connector doesn't support any of the entity operations, such unsupported operations aren't listed in the Operations list.

• Action: An action is a first class function that is made available to the integration through the connector interface. An action lets you make changes to an entity or entities, and vary from connector to connector. Normally, an action will have some input parameters, and an output parameter. However, it is possible that a connector doesn't support any action, in which case the Actions list will be empty.

Note: All entities and actions will have a schema associated with them. For example, an action schema will have the parameter details such as; the parameter names, and its corresponding data type. The schema (metadata) for entities and actions is fetched by the connection at runtime from your backend. If there are any updates to the schema, such updates won't be automatically reflected in your existing connections; you must manually refresh the schema. To refresh the schema for a connection, open the Connection details page of the connection, and then click Refresh connection schema.

Actions

The Confluence connector provides actions such as DownloadAttachment and UploadAttachment. To understand how to configure the actions, see Action examples.
