myPOS + Exely: Easy Integration Guide

This guide shows how to connect your myPOS account to Exely Booking Engine and start accepting online payments for hotel reservations.

Exely also supports pre-authorization, which lets you reserve funds when needed. Pre-authorization is not enabled by default. To activate it, contact integrations@mypos.com.

What You'll Do

  1. Create a myPOS Checkout for your hotel.
  2. Collect 5 required parameters from myPOS.
  3. Share these parameters with Exely so they can complete the setup.
  4. (Optional) Request pre-authorization activation from integrations@mypos.com.

What You Need for Exely

After creating your Checkout, send Exely these 5 items:

  1. Private Key
  2. Public Certificate
  3. Key Index
  4. Store ID
  5. Client Number

Step-by-Step: Connect myPOS to Exely

1. Create a New Checkout in myPOS

  1. Log in to your myPOS account.
  2. Go to Stores > eCommerce.
  3. Select Create Checkout and complete the setup wizard.

2. Choose Your Currencies

Important: The currency in myPOS should match the currency used for Exely reservations.

  • Accept bookings in EUR? Enable EUR.
  • Want to accept BGN, GBP, or others? Add those currencies too.

You can add more currencies later: Stores > eCommerce > [Your Checkout] > Settings > Transaction currencies

Each hotel can have its own Checkout and separate currency accounts.

3. Generate Your Keys

  1. Go to the Integration tab in your Checkout.
  2. Click to generate a new key pair.
  3. Save your Private Key in a secure location (you can see it only once).
  4. Download your Public Certificate (you can re-download this later).

Lost your Private Key? Generate a new key pair and share the new details with Exely.

4. Find the Key Index

In the Integration tab, find the Key Index. This number identifies your key pair.

Send the Key Index to Exely together with your keys.

5. Get Your Store ID and Client Number

  • Store ID (SID):
    • Find this in your Checkout's general information.
  • Client Number:
    • Find this in your myPOS account under Company Information.

6. Send Everything to Exely

Once you have all 5 parameters, email them to Exely at 📧 support@exely.bg.

If you plan to use pre-authorization, also contact 📧 online@mypos.com to activate this feature.
