Configure the Base API

In the Base API tab, you configure the base URL for the application API and pagination:

  • Base URL – Automatically filled with the value declared at connector creation.
  • Pagination type – Options available in the drop-down are: Page start with 1, Page starts with 0, Offset, Custom. If the vendor documentation doesn’t provide any details on pagination, keep the default value.
  • Pagination max – Default value is 100. If the vendor documentation doesn’t provide any details on pagination, keep the default value.

Set the authentication method

In the Authentication tab, you configure the authentication type for your connector. Supported options are:

  • Basic
  • OAuth 2.0:
    • Authorization Code
    • Authorization code with PKCE
    • Client Credentials
  • API Key
  • Personal Access Token (PAT)
  • No Authentication

📘

Note:

When configuring the authentication, you are configuring how anybody using your connector needs to authenticate. This will be you while you are building the connector, but could also be others that end up using your creation.

Basic authentication

  1. Click the edit icon under the Action column to configure each property. Username and Password are available by default.
  2. Click Add parameter if you want to add another field to be used during authentication:
    • Display name – Shown to the user when connecting.
    • Type – Defines the input field on the connection dialog. Select an option from the drop-down: true/false, password, test, yes/no.
    • Ask the user – Set to Yes when user input is required.
    • Value – Use this field to set a default value.
    • Hint text – User guidance for the input field.
    • Provider name - The technical key for the API call.
    • Send to provider as type – How the API receives the value. Select an option from the drop-down: configuration, header, path, body, query, form. Default value: header.

  1. Click Save to save your new authentication parameter.
  2. Use the Reset to default option if you want to reset your authentication to the original values for Basic. This operation cannot be undone.

OAuth 2.0 Authorization Code

To use OAuth 2.0 Authorization Code, you need to create an OAuth app in the application you want to integrate with, and retrieve from there the credentials necessary for configuring your connector.

Configure the following fields:

  • Client ID
  • Client secret
  • Scope
  • Authorization URL
  • Token URL
  • Refresh token URL
  • Basic header
  • Token revoke URL
  • Refresh interval

📘

Note:

The Authorization, Token, and Refresh token URLs should be available in the app's API documentation.

OAuth 2.0 Authorization Code with PKCE

OAuth 2.0 Authorization Code with PKCE is identical to the OAuth 2.0 Authorization Code method, but it also include the OAuth2 PKCE Code Challenge Method field.

Personal Access Token

Use this option for integrating with apps that require a bearer token to make API calls against.
Set the Personal Access Token field to your bearer token.

17111711

No authentication

Use this option if you don’t need users to authenticate to use the connector.

Test your connection

Once you have completed the authentication configuration, select Add connection from the drop-down menu:
If your connection is successful, the status is updated to Connected.

Resources

The Connector Builder generates the list of resources based on the provided API definition.
The left-side menu displays the list of available resources, organized in groups.

Configure your resources

When you select a resource, the following window is displayed:

25602560

Depending on the resource method you select, the following configuration tabs are available: Parameters, Response/Request Fields, Pagination, Search.

Parameters

For example, all four tabs are available for GET methods. For POST methods, you can only see the Parameters, Request Fields, and Response Fields tabs.

In Parameters, you can view the list available parameters for the selected resource, add new parameters or import parameters from an existing resource.

The parameters listed in this table are the ones you will use in Studio when building automations using your custom connector.

For example, here is a Get record activity from the Connector Builder activity pack:

10521052

The Pet object corresponds to the Pet resource group, and the available fields are the ones set for the GETBYID resource:

Response and Request fields

The Response and Request fields for each resource are automatically generated upon sending a request.

In each respective tab, you can edit or delete any field. If you click the Edit icon, the following configuration window is displayed:

In the Response/Request fields tab, the following options are also available:

Pagination

Enable Pagination for a resource if you expect a list response. If you enable pagination, you also need to define the Response root key in the configuration tab, for nested lists.

Search

Activate the Enable Search checkbox to allow search setup for a resource.

After you configure everything you need, you can continue with Publishing your connector.
