Introduction

Getting Started

Get invited. Your Delivr contact creates your organization and emails an invitation. Accept it and sign in at app.delivr.ai. Inviting more teammates is self-serve from there.
Authentication: create an organization API key + secret at https://app.delivr.ai/{org_id}/settings/api-keys
Account Setup: create a project and pixel

Then pick a path:

API Hosts

Host	Used For	Auth
`apiv3.delivr.ai`	Data APIs: events (v2), audiences, taxonomy, identity lookup	`X-Api-Key` + `X-Api-Secret`
`api.delivr.ai`	App, project, pixel management (Partner API), field catalog, UID2 conversion	Platform JWT + `X-Delivr-Client-ID`/`Secret`
`apiv2.delivr.ai`	Legacy. Use `apiv3` for all new integrations	(legacy)

New integrations should use apiv3.delivr.ai with an organization API key + secret pair, and the v2 events endpoints (/api/v2/events*). Migrating from apiv2? See the API Migration Guide. For a full comparison of all three hosts, see the API Host Comparison.
