The Vendor Account Toggle Is Disabled in Connect Card

Issue

The Vendor Account toggle is disabled when an end user attempts to authenticate an Amazon Selling Partner connection using a Connect Card. The user cannot select or change the toggle before clicking Save & Test.

Environment

• Connector: Amazon Selling Partner
• Connect Cards

Resolution

To resolve this issue, you must create a new Amazon Selling Partner connection and set the Vendor Account value in the API request body. The Vendor Account toggle is controlled by the is_vendor field. Set is_vendor to true in the connection configuration:

"config": {
  "is_vendor": true,
  "merchant_id": "test_merchant_id",
  "historical_sync_time_frame": "ALL_TIME",
  "region": "NORTH_AMERICA",
  "schema": ""
}

You can't update this value for an existing connection in the Fivetran dashboard or using the REST API.

Cause

In the Connect Card flow, the connection is created through the REST API before the end user opens the Connect Card. The connection type cannot be changed after connection creation, so the Vendor Account toggle is already disabled when the end user opens the Connect Card.
