Moloco Cloud - Troubleshooting

While configuring your Moloco Cloud connection, you may encounter several issues. Understanding these common errors can help streamline the setup process and facilitate quick resolutions.

Authentication fails with “Need to use an API key to issue the token”

The connection is still on the retired login and password flow. Moloco Cloud issues an access token only in exchange for an API key, and Improvado moved the connector to that flow in June 2025. A connection created before the change holds a password where Moloco now expects a key, so token generation fails on the first request and every extraction order on that connection stops.

To fix it, generate an API key in the Moloco Ads Portal, then open the connection in your Connected sources list and re-connect it with Email, API Key and Workplace ID. See How to Configure Connected Sources for working with an existing connection.
