# Authentication

## Overview

The RealmJoin backend expects application credentials (username and secret).

Username and secret will be created for you by our RealmJoin operations team. Please feel free to reach out if you want to integrate RealmJoin into your own tools and processes!

## Example

For the sake of demonstration, let us assume the username created for you is `t-12341234`and the secret is `myS3cret!`.

To authenticate, concatenate username and password, separated by a colon (`t-12341234:myS3cret!)`and encode this into a Base64-String.

Our example username and secret will encode to `dC0xMjM0MTIzNDpteVMzY3JldCE=`

Now, on every request against the RealmJoins backend service present an http header with the resulting Authorization:

```
Authorization: Basic dC0xMjM0MTIzNDpteVMzY3JldCE=
```

RealmJoin will then allow you to interact with resources in your environment. It will not allow you to interact with resources foreign to your tenant. Remember that RealmJoin Portal requires SSL/TLS transport layer encryption on every request - your credentials will not be exposed to the traversing networks.

## 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.realmjoin.com/dev-reference/realmjoin-api/authentication.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.
