# Welcome

Connect to attractions, tours, and activities running on Ventrata through the OCTO API — one integration, every supplier who switches you on.

This documentation covers Ventrata's implementation of the [OCTO API Specification](https://docs.octo.travel/), for resellers — OTAs, marketplaces, city card operators, and other distributors — connecting to suppliers that use Ventrata as their ticketing platform.

You build once. Every Ventrata-powered supplier who switches you on is then reachable through the same integration, with no per-supplier development.

{% hint style="success" %}
**No fees, and a free test account.** There is no charge for resellers working with Ventrata clients to use the OCTO API or the support that comes with it — and you can build and test against our test Supplier account before you are certified.

## About OCTO

OCTO (Open Connectivity for Tours, Activities and Attractions) is an open standard API specification for the in-destination experiences sector. It defines agreed schemas, endpoints, and capabilities for connecting reservation systems, resellers, OTAs, and other technology in tours, activities, and attractions. It is developed and administered by a member-based not-for-profit, OCTO Standards NP Inc.

Ventrata is a founding member and one of the earliest adopters. OCTO is also implemented by Peek Pro, Xola, Zaui, Anchor, and others — so the work you do here carries over to other platforms.
