🛠️ Setup guide (5 Steps)

1. Install the TYPO3 Extension

Install the TYPO3 ChatBot Extension EasyChat via composer:

composer require undkonsorten/easychat

After installation a database compare is necessary (via Install Tool or TYPO3 Console) to create new tables.

2. Configure the LLM provider

Now you need to connect TYPO3 to your LLM's provider via API. Create a new database record "Configuration" in TYPO3.

Then fill out the fields of the Configuration record.

Sample configurations for you LLM

• Mistral (Free plan available | How to get an API key?)

  • Name: Mistral (mistral-tiny)
  • Model (of the LLM): mistral-tiny
  • URL (of the API endpoint): https://api.mistral.ai
  • API Key: your-api-key-abc123xyz-...
  • System Message (Promt): You are a support chatbot ...

• OpenAI / ChatGPT (Payed plan only | How to get an API key?)

  • Name: Chatbot via OpenAI (gpt-4o-mini)
  • Model (of the LLM): gpt-4o-mini
  • URL (of the API endpoint): https://api.openai.com
  • API Key: your-api-key-abc123xyz-...
  • System Message (Promt): You are a support chatbot ...

• mittwald (Payed plan | How to get an API key?)

  • Name: Support Chatbot via Mittwald (gpt-oss)
  • URL (of the API endpoint): https://llm.aihosting.mittwald.de
  • Model (of the LLM): gpt-oss-120b
  • API Key: abc123xyz...
  • System Message (Promt): You are a support chatbot ...

3. Setup the TYPO3 Reaction

A TYPO3 Reaction needs to be created. The reaction serves as a connector (aka endpoint) between the chat frontend and TYPO3.

• Create a new reaction with the Reaction Type Reaction for easychat.
• Be sure to copy the generated secret before saving
• Chose one of the before created EasyChat configuration record

After sucessfully creating the reaction you will see the following interface.

Now also copy the reaction URL (like https://my-domain.com/typo3/reaction/afce5efb-861e-4e0e-8a8b-d159f194670d). You will need it in step 4.

4. Setup the Content Element

Last but not least you need to setup a content element for the chatbot.

• Be sure to have you Reaction URL and secret available.

• Open a TYPO3 page

• Add/create a new content element "Chatbot".

• Connect the content Element to the reaction.

✨ YOU ARE DONE!!! 👊 CONGRATULATIONS 🎉

Theming & Templates

Chat Fronend: Deep Chat

EasyChat comes along with Deep Chat - an open source chat web component in the frontend.

For simplicity we integrated Deep Chat as a plain Vanilla JS web component, but it can be used with many other frameworks (e.g. React, Vue, Svele, Angular). EasyChat is able to communicate with popular AI providers, but can also connect to your own servers - in our example with TYPO3.

DeepChat is an example implemention. Feel free to use another chatbot frontend. The default dummy template is located at

• /Resources/Private/Templates/ChatFrontend.html.

Styled version

If you want to use our suggested default styles for ChatBot & Cookie Consent you need to include the TypoScript templates in /Configuration/Styling/.

How to add your own styles 💐

You can either overlay the default template or the styled template, by setting your own template paths.

# overlay the easychat styled version
plugin.tx_easychat.view {
    partialRootPaths.10 = EXT:my-sitepackage/Resources/Private/_Default/Easychat/Partials/
    templateRootPaths.10 = EXT:my-sitepackage/Resources/Private/_Default/Easychat/Templates/
}

Be aware,

• there a many ways to inject styles to a web component like <deep-chat>
• keep also in mind the styles for the chatbot trigger button and the consent module

How to Change the texts

Your edit some of the content directly in the Frontend.

You can ovverride texts used in the template via locallang.xml oder via TypoScript.

plugin.tx_easychat {
    _LOCAL_LANG {
        default.easychat_nagscreenMessage = Hast du Fragen zu unserem Angebot?
        default.easychat_dataProtectionConsentAcceptedMessage = Einwilligung erteilt
    }
}
