Adalo already lets you connect directly to ChatGPT through Custom Actions (API calls). You don’t need a heavy backend if you’re okay with putting your OpenAI API key in Adalo’s hidden header settings.
The flow is:
User enters text → Adalo sends it via a Custom Action (POST) to the OpenAI API.
ChatGPT replies → the response is saved into a property in your Collection (like reply) or a temporary variable.
