# Authentication

Several web services of the API provided by the dydu solution require authentication ("Authorization" field of the API).

Authentication is of type: Basic Authentication.

It is therefore necessary to build a token and use it in the headers of your requests.

To build the token, you must:

1. Associate your login, the character ":" and your password (paying attention to the case);
2. Encode this string in base64;
3. Add Basic.

Example:

1. <demo@dydu.ai>:MyPassword
2. ZGVtb0Bkb3lvdWRyZWFtdXAuY29tOk1vbk1vdERlUGFzc2U=
3. Basic ZGVtb0Bkb3lvdWRyZWFtdXAuY29tOk1vbk1vdERlUGFzc2U=

You will be able to generate your token (**Authorization**) from https\://**urlbackoffice**.doyoudreamup.com/servlet/authentication.html

Important: remember to replace **urlbackoffice** with the URL of your platform.

Enter your login and password and click **Generate**.
