# Seller download codes

In GUIBO, each release needs to have a unique download code. This code is presented within the Trip Link travelers use to download their personalized travel documents into the app.

Typically the download code matches the tour operator's booking reference number to make it easy to match booking related GUIBO releases (including Trip Links) with bookings in the tour operator's booking system.

For shared releases, tour operators can set an additional seller download code. Typically the seller download code matches the seller's booking reference number. This way, both sides (tour operator and reseller) can easily match GUIBO releases with related bookings in their booking systems.

### How to set the seller download code

#### Set the seller download code when the release is created

The first option to provide a specific seller download code is when the release is created. At this point in time, the operator is typically aware of his own booking reference number as well as the booking reference number from the reseller who provided the booking request initially. This way, the reseller can easily match the GUIBO release with its related booking.

If there is no seller download code provided, GUIBO creates a random number.

#### Change the seller download code in the release dashboad

In the release dashboard, the operator as well as the reseller can change the seller download code.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.guibo.travel/publishing/b2b-network/for-tour-operators/share-bookings/seller-download-codes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
