# Third party applications

**How to connect to MessageBird?**

If you need to integrate your application to MessageBird, first check our official [Integrations](https://www.messagebird.com/en/integrations/) and see if the application you use is one of them.

If your application is not listed, you will need to check how your application connects to other applications, like MessageBird.

**Does your application require an access/authorization key to connect to other applications?**

Then use our [REST API](https://developers.messagebird.com/). You can create/manage keys in your MessageBird Dashboard [here](https://dashboard.messagebird.com/en-gb/developers/access).

**Does your application require a username and password to connect to other applications?**

Then use our [Old API](https://www.messagebird.com/en/developers-old/). You can create/manage your username and password in your MessageBird Dashboard [here](https://dashboard.messagebird.com/en-gb/developers/access-v1).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bird.com/connectivity-platform/getting-started/third-party-applications.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
