3. Connect their checkout

Once a merchant is approved, you give them a key that lets their website take payments through us — under your brand.

  1. 1

    Open Sites & keys

    On the merchant's card (under Sub-merchants), click Sites & keys.
  2. 2

    Add their website

    Under Sites, paste the merchant's website and click Add site. This is where their checkout will run.
  3. 3

    Generate an API key

    Under API keys, give it a name and click Generate. Start with a Test key; the Live key unlocks once the merchant is approved.
  4. 4

    Copy it now

    The key is shown only once. Copy it the moment it appears. If you lose it, just generate a new one.
  5. 5

    Hand it over

    Send the key to the merchant or their developer to plug into their checkout. From their customers' point of view, the whole payment experience is yours — they never see us.
Treat the Live key like a password. Anyone with it can create real charges on that merchant's account. Share it over a secure channel, and generate a fresh one if it ever leaks.

What the developer does with it

The key plugs into our standard payments API — the same one any merchant uses. Your merchant's developer can follow the API documentation to create payments, set up webhooks and so on. Nothing about the integration is reseller-specific; the key simply belongs to that sub-merchant.

Each payment type still needs to be switched on for the merchant's site (for example, cards or crypto). We enable these during review, the same as for any merchant. If a method isn't showing, let us know and we'll turn it on.
