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
Open Sites & keys
On the merchant's card (under Sub-merchants), click Sites & keys. - 2
Add their website
Under Sites, paste the merchant's website and click Add site. This is where their checkout will run. - 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
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
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.
