Using the external reference
In order to avoid having to manage the seller IDs of the Marketplace API, you can specify an external reference (your own) which you can then use in queries for order creation, cashout filters, etc.
To do this, simply add the attribute external_ref in the registration.
You can use up to 50 characters for this field.
For example:
json { "external_ref": "SSLLR314_ANIERS" }
