# Partners working on behalf of merchants

Administration tasks includes:

* Terminals
* Users
* Api keys
* Products
* Spots

It is possible to 'Work on behalf' using our API or directly from the Payment Platform. 

### In the Payment Platform

When logging in as a partner, a dropdown enables partners to select between connected merchants.

When selecting a merchant all operations will change data for that merchant.

### Using the API

Whether you code, use a tool (like Postman) or you use Swagger docs it is possible to provide an accountId in the header of your request and this enables you to 'work on behalf'.

&#x20;Simply add the header: `accountIdOnBehalfOf` - and all will work like a charm.
