Slotted developer documentation
Guides and API references for integrating with Slotted. API keys are not created from this site — referral partners receive invite-only keys from Slotted; providers create Shipping Cohort Rate Engine keys in the in-app Developer Portal.
Security: These docs describe allowlisted public endpoints only. They do not expose admin APIs, JWT app routes, or production Try-it against live customer data. Use sandbox credentials for exploration.
For approved referral partners
Short List Referral
Send brand fulfillment opportunities into Slotted so brands can claim them and run a structured RFP with your recommended providers.
For 3PL providers
Shipping Cohort Rate Engine
Connect your shipping rate engine so Slotted can request cohort rates on proposals — whoami, cohorts, ratings, and outbound webhooks.
