# Choosing your API

Xenioo offers multiple endpoints that can be used by any external application to extract data, integrate or create automatic messaging for your chatbot.

| [Custom Channel  API](/basic-concepts/publishing/channels/customchannel.md)                              | This is your main API if your target is to build your own, custom chat application, while leveraging Xenioo advanced flow system and AI engine or to simply use Xenioo channels as communication bridges for your own, custom chatbot solution. |
| [Chatbot Events API](/basic-concepts/chatbot-details/chatbot-settings/integration.md#events-webhook-url) | Integrate with these API if your project needs to receive all of the conversation messages and events that are related to your chatbot usage.                                                                                                   |

| [Database API](/database/database-api-access.md)                                                         | Use these API if your application needs to remotely access Xenioo Database Collections                                                                                                                                                          |
