API merXu

In order to use the REST API, it is necessary to generate access data for the application (client_id and client_secret). This data is generated once for each integration, regardless of the number of users or queries performed.

To generate your access data, please contact

In order to use most of the functionalities it is necessary to authenticate with user data. For this purpose, it is necessary to enter a login and a password. For maximum security, we suggest generating a dedicated password for each integration:

After logging in ( the user receives two tokens:

  • accessToken — a token to be used at each subsequent request for authentication. The token is valid for 30 minutes.
  • refreshToken — a token used to generate a new accessToken.

API is available in all languages supported by merXu. To receive data in the desired language, use the accept-language header ( / Accept-Language) — eg. “Accept-language: pl-PL” or “Accept-language: pl”.
