# Deep Links into Go Book and Go Join

HTML version: [Deep Links into Go Book and Go Join](https://support.gladstonesoftware.cloud/gooperator/deep-links-into-go-book-and-go-join)

## Problem
You need to understand what deep links Go Book and Go Join support, and which article covers each kind. A deep link is a web address that takes a customer straight to a pre-filled booking search, an activity calendar or a membership.

## Resolution

1. **[Creating Deep Links for Activity and Class Bookings in Gladstone Go](../goconsumer/creating-deep-links-for-activity-and-class-bookings-in-gladstone-go.md)**
   - When linking to a booking search for a site, activity group or activity, an activity calendar, or a single class session on Go Book.

2. **[Creating Deep Links for Membership Purchase in GladstoneGo](creating-deep-links-for-membership-purchase-in-gladstonego.md)**
   - When linking to a site group, a site's memberships, one pre-selected membership or its payment breakdown on Go Join, including generating the link in Operator.

## Notes

- Both kinds of link can open in Welsh or English by adding `cy_GB` or `en_GB` straight after your domain, and both accept tracking tags such as `utm_source`.
