Happn-Ed

Happn Educational is my attempt to learn the backend of Happn. After digging into the working of Tinder, I got interested in getting a date for me even more when Saraswati Puja is approaching. But small talks away, I started digging into the backend by observing the API requests using the all time trustworthy tool, BurpSuite.

FAQ

How to use the API?

The API have defined endpoints that accepts requests as documented above. Every POST request need the OAuth token to be supplied in the request body and it returns the response.

How can I get my OAuth token?

Login to Happn from your browser and open dev tools. In the storage sections, see the local storage and find a key named accesstoken. The value of that key is important for the API to work.

The token that worked previously is not working now. What to do?

Happn refreshes tokens at regular intervals or after you re-login. Just use the new token and the API will be functional again.

Why did you I make this crazy thing in the first place?

To demonstrate my backend skills, make matching easier in Happn and have a working proof of my findings and skills to include in CV. Have to bag a job in 2024 :)

Are you still single even after enumerating and playing with dating applications?

Yes, I am still single and I see no hope of getting anyone any sooner.
