How many football API leagues does your app need at launch?

Contents Choosing how many football API leagues to launch with starts with a familiar decision: an English fan app needs the Premier League, but including the FA Cup and Carabao Cup makes its domestic shortlist three competitions. A single-competition fantasy game can start with one, a comparison tool covering Europe's main domestic leagues needs five, and adding Brazil, Mexico and the US brings that example to eight.
We have 2,200+ leagues in one format, so start with the competitions your users follow, count cups separately and check the fields each feature needs before expanding the same integration. Start from your users, not the league count Choosing football API leagues starts with a product promise.
Write one sentence describing who the app serves and what they can do with it. "Follow English clubs across their domestic and European fixtures" creates a different shortlist from "compare forwards in the five biggest European domestic leagues.
The first follows clubs across competitions; the second follows a defined group of leagues. For an existing app, look at competition searches, followed teams, match-page visits and requests to support.
For a new product, ask prospective customers which teams and competitions they expect to find. Their home country helps you start the conversation, but it does not tell you every competition they follow.
A fan living in the Netherlands may also follow an English club. Count football API leagues and cups separately One country can contain several relevant competitions: a top division, lower divisions, domestic cups and women's football.
A country selector in your interface is a navigation choice, not a reliable way to calculate subscription scope. A club's domestic league also does not contain its cup fixtures.
If your promise covers every match a club plays, check its other competitions too. Decide how you will handle a club reaching a new tournament or moving between divisions.
These are changes to your shortlist, even when your app still serves the same supporters. Split the list into launch and later."
