High-level integration overview
1. What is a download service?
A Music Download Service allows you to sell your licenced catalogue to your end users in various different audio formats. You have full control over the retail price that you wish to charge customers, and can be confident that your monthly rights holders sales reports are accurate via the use of the MassiveMusic API endpoints listed in this guide.
2. Setting up your users
For each user of your download service, you need to create a user with MassiveMusic. When creating a user simply use a unique identifier as MassiveMusic will not store any other identifiable or login information (e.g. passwords, usernames).
Use the following endpoint to create a new user:

About "retailPrice"If you are charging your users a price which is different from the MassiveMusic RRP, then you must specify this attribute with the correct sale value.
This field must include fractional units in decimal form where relevant for the currency in question, eg. "7.99", "1.00". The price cannot be negative and must not be more than 2 decimal places. The price should not include any commas (",").
If you're giving away items for free please use retailPrice=0, if you're using vouchers or you're not sure what to report please contact our client success team.
