13 APIs to Help You Build a Dating App

Today, we are forced to stay home, and communicate with the outside world through a phone or a computer. And this is triggering a radical change in which people require more immediate, engaging and innovative ways for facilitating online interactions that enable the exchange of experiences and emotions.

Even if the pandemic has led to general growth for the dating app business, it also brings new challenges and difficulties. But every problem has its own solution. For example, to overcome the problem of social distancing, Tinder is providing a new way for people to interact via video dating.

Normally, building video calling capabilities requires weeks of work, additional cost, and time. Readymade APIs can speed up the process allowing you to save energy, time, and money. Here’s a list of APIs for dating app developers

The FusionAuth web UI is built upon these APIs, with the exception of managing API keys everything in the UI is available through an API.” The most popular features are Single Sign-on (SSO), Passwordless login, Social Logins, Registration Forms, and many others.

Authentication is a very important feature for every app, in online dating, it prevents users from creating multiple or/and fake profiles and improves the overall professional public image of the app.

In dating apps, as in many other things, it is very important to have good management of users, especially emails.

Zero Bounce will help you validate users to clean out fake profiles, and spare management costs (maintaining a huge mailing list can be expensive), reduce your spam complaints and finally, to increase that open rate! Also, their service will allow you to detect where your mails will land (inbox, spam or not delivered) and to keep testing and adjusting until you reach the inbox. They also alert you if your domain / IP is blacklisted. This feature is available for freemium users.
