Support

Support description

Support is through live chat and a help desk, with a documentation hub. Implementation experts handle technical updates for customers. No support hours or response times are published.

Google documents the setup in its developer guides. There is no vendor support specific to this setup in the pages reviewed; support depends on your Google Cloud support plan.

Dutch-language support by support ticket and email, with an answer promised within 24 hours on the pricing page. A help center at docs.adpage.io covers setup, integrations and troubleshooting. Docs also separate support tickets from consultancy projects.

Base plan customers get an in-app chatbot and a knowledge base. Core and Advanced plans get in-app support tickets with a stated response within 24 hours, and Premium and Elite get priority support within 12 hours. Paid add-ons include implementation services and analyst services.
