Paypal

The Paypal connector lets you connect to a Paypal instance and perform the supported Paypal operations.

Before you begin

Before using the Paypal 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 Paypal 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, 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.
   8. Signature: The signature required to use the SOAP API.
   9. Include Details: A Boolean value indicating if you will get extra details (for example, the ShippingAddress fields when querying the Invoices table).
   10. Schema: The type of schema to use.
   11. Use Sandbox: A Boolean value indicating if you are using a Sandbox account.
   12. Use proxy: Select this checkbox to configure a proxy server for the connection and configure the following values:
   • Proxy Auth Scheme: Select the authentication type to authenticate with the proxy server. The following authentication types are supported:
     • Basic: Basic HTTP authentication.
     • Digest: Digest HTTP authentication.
   • Proxy User: A user name to be used to authenticate with the proxy server.
   • Proxy Password: The Secret manager secret of the user's password.
   • Proxy SSL Type: The SSL type to use when connecting to the proxy server. The following authentication types are supported:
     • Auto: Default setting. If the URL is an HTTPS URL, then the Tunnel option is used. If the URL is an HTTP URL, then the NEVER option is used.
     • Always: The connection is always SSL enabled.
     • Never: The connection is not SSL enabled.
     • Tunnel: The connection is through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy.
   • In the Proxy Server section, enter details of the proxy server.
     1. Click + Add destination.
     2. Select a Destination Type.
        • Host address: Specify the hostname or IP address of the destination.

          If you want to establish a private connection to your backend system, do the following:

          • Create a PSC service attachment.
          • Create an endpoint attachment and then enter the details of the endpoint attachment in the Host address field.
   13. Optionally, click + ADD LABEL to add a label to the Connection in the form of a key/value pair.
   14. Click NEXT.
5. 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 Paypal connection:

      • Username and password

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

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

Configure authentication

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

• Username and password
  • Username: Username for connector
  • Password: Secret Manager Secret containing the password associated with the connector.

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.

Use terraform to create connections

You can use the Terraform resource to create a new connection.

To learn how to apply or remove a Terraform configuration, see Basic Terraform commands.

To view a sample terraform template for connection creation, see sample template.

When creating this connection by using Terraform, you must set the following variables in your Terraform configuration file:

Parameter name	Data type	Required	Description
signature	STRING	True	The signature required to use the SOAP API.
include_details	BOOLEAN	False	A Boolean value indicating if you will get extra details (for example, the ShippingAddress fields when querying the Invoices table).
schema	ENUM	True	The type of schema to use. Supported values are: REST, SOAP
use_sandbox	BOOLEAN	True	A Boolean value indicating if you are using a Sandbox account.
proxy_enabled	BOOLEAN	False	Select this checkbox to configure a proxy server for the connection.
proxy_auth_scheme	ENUM	False	The authentication type to use to authenticate to the ProxyServer proxy. Supported values are: BASIC, DIGEST, NONE
proxy_user	STRING	False	A user name to be used to authenticate to the ProxyServer proxy.
proxy_password	SECRET	False	A password to be used to authenticate to the ProxyServer proxy.
proxy_ssltype	ENUM	False	The SSL type to use when connecting to the ProxyServer proxy. Supported values are: AUTO, ALWAYS, NEVER, TUNNEL
