Intro

Lets a sub-merchant check which marketplace operator they’re linked to and the commission rate currently applied to their sales.

Context

This is the sub-merchant-facing counterpart to the operator-facing marketplace endpoints. Call this with a sub-merchant’s own API key — not the operator’s — to find out which marketplace they’re linked to. Unlike most other /marketplace/* endpoints, it is not restricted to marketplace operators.
The commission_rate returned here reflects any per-merchant override the operator has set via Update Commission or Update Merchant — this is the rate that will actually apply the next time Create Charge processes a marketplace sale for this merchant.

Hows

Response

marketplace only includes id and educator_email — no business/display name is returned by this endpoint today, and note the field is educator_email here rather than the business_email name other partner endpoints use. commission_rate is this caller’s own effective rate, not the operator’s default — it already reflects any per-merchant override set via Update Commission.
commission_rate is returned as the raw decimal value — a string like "0.0500", or null if never set — not a JS number. Parse it with Number(...) before doing arithmetic.
If you’re not currently linked to any marketplace, data.marketplace is absent entirely — see the 404 below.

Error Codes

Whys

Sub-merchants need visibility into their own marketplace relationship and effective rate without needing operator-level permissions — a merchant reconciling their own payouts shouldn’t have to ask their marketplace operator what rate is being applied. Keeping this endpoint open to any linked sub-merchant (rather than gating it behind marketplace-operator status like most /marketplace/* routes) reflects that it answers “what’s happening to my account,” not “what am I operating.”

Why nots

This does not return the operator’s marketplace name, branding, or any other profile detail — just enough to identify which account you’re linked to. It does not let a sub-merchant change their own commission rate or leave the marketplace — those actions belong to the operator via Update Commission and Remove Merchant.
