Sailer API

A REST API for the contacts, conversations, and campaigns in your Sailer workspace.

The Sailer API lets you read and write the same records your team works with in the product: contacts, the conversations they are having, and the campaigns they belong to.

Early access. The /v1 contract below is stable and versioned, but not every resource is live yet. This page lists what you can call today.

Available today

Resource	Operations
Contacts	List, search, create, retrieve, update, upsert
Meta	Describe your token (/v1/me), read workspace capabilities (/v1/capabilities)

Organizations, deals, pipelines, notes, activities, tags, conversations, and campaigns are part of the /v1 design and will appear here as they ship. The tags already exist in the reference so you can see where they will land.

Every endpoint is under /v1. The version is in the path, so a future /v2 can land without breaking anything you build today.
