How to connect to MyDATA through Hosthub (Oxygen integration)

The connection to MyDATA in Hosthub is made through the Hosthub integration with Oxygen, a certified electronic invoicing/ERP provider. Once connected, you can issue booking documents (such as Service Receipts / ΑΠΥ) and have them automatically transmitted to MyDATA.

Steps to connect

If you are a business obliged to issue documents, follow these steps:

1. Create an account with Oxygen using this link to receive the special reduced price for Hosthub users: https://app.pelatologio.gr/register.php?pcode=phosthub&bn=pcp
2. Contact Oxygen and request an API key for your account.
3. Send the following to Hosthub via chat:

• The API key provided by Oxygen
• The username (email) of your Oxygen account

4. Once received, Hosthub will proceed with activating the integration.

Before this, make sure you have also set the tax settings for every property. Go to Setup > Properties, click on the property name, select Tax settings, click Edit, enter the tax details, and save. This must be done for all properties for the correct calculation of the submitted amounts.

Multiple owners / properties

You can connect multiple Oxygen accounts through Hosthub — one for each VAT number (ΑΦΜ)/owner — and issue documents such as Service Receipts (ΑΠΥ) and the special TAAK (resilience fee) document separately for each booking, with automatic transmission to MyDATA.

Pricing and Pro plan

The Oxygen connection is not included in the basic plan and has an additional cost. If you are a Pro plan user, you can pay for the Oxygen package, send Hosthub the transaction receipt issued by Oxygen, and this amount will be covered through a discount on your Pro package.

Supported providers

Currently, Hosthub supports the MyDATA integration only through Oxygen. Other providers such as Epsilon Net are not supported. You can continue to use another provider like Epsilon Net separately, but it will not connect to Hosthub.

Automatic booking submission to the ΑΑΔΕ Registry and MyDATA

Automatic submission of bookings to the ΑΑΔΕ Registry and MyDATA through Hosthub requires the Pro plan. Without the Pro plan you will not get automatic booking submission, but you can still issue and send booking documents provided you have activated the Oxygen integration.
