SailySaaS REST API Documentation

Integrate SailySaaS CRM into your internal portals, browser extensions, customer apps, and automation pipelines.

The SailySaaS API is built on RESTful principles. It accepts JSON-encoded request bodies, returns standard HTTP response codes, and uses Bearer tokens for secure, organization-scoped authentication.

Base URL: https://sailysaas.signimus.com/api

Authentication

All API requests must include your API token in the Authorization header using the Bearer scheme.

HTTP Header Example 
Authorization: Bearer nxtc__a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6
Content-Type: application/json

Organization Resolution: API tokens prefixed with nxtc__ are tied to a specific user and their active organization. You do NOT need to pass organizationId in request bodies; it is automatically resolved from your token.
