Who this is for: Brand administrators coordinating partner integrations, and integration developers building against the API. API keys are not created inside the Keystone app.
The Inventory API lets retail partners and integrators query your brand’s sellable inventory by SKU, region, and incoming purchase order dates — without logging into Keystone.

​
How partners get access

API keys are issued per tenant by the Keystone team. They are not self-service in the app dashboard. To request a key, contact your Keystone account representative or email support@keystoneb2b.io. Include:
  • Your company name
  • The partner or system that will use the key
  • Whether you need production or staging credentials

​
Using a key

Partners send the key in the Authorization header of every request:
See the Authentication guide for full integration instructions, base URLs, and security requirements.

​
Security best practices

API keys are server-side only. Never embed them in browsers, mobile apps, or public repositories.
  • Issue one key per partner integration.
  • Rotate keys immediately if you suspect exposure.
  • Revoke access promptly when a partner relationship ends.
  • Use HTTPS for all requests (enforced on the production endpoint).
To rotate or revoke a key, contact support@keystoneb2b.io.
