No details how to deploy mongodb to heroku

Challenge URL Shortener Microservice has an issue.

There are no Details for deploying mongodb in heroku… Its my first time i am trying to deploy a db into heroku and i am finding it hard.

At last i found out a way to do this is adding mLab MongoDB add-on but it is asking for a credit card for billing , Not all people will have a credit card, Is there any better alternative for this? or anyother better way to do this Challenge other than using a DB.

or if in case i am assuming this in wrong way please tell me and close this issue. my code is at https://github.com/ChaituVR/URL-Shortner.git

Thank you

@ChaituVR Thanks.

After the wiki is merged we need a PR to refer that in the challenge.

A line needs to be added here: https://github.com/FreeCodeCamp/FreeCodeCamp/blob/staging/seed/challenges/03-back-end-development-certification/api-projects.json#L261 and any translations (if unsure, just add the english version, there as well, its fine and can be updated later) that are there on the page.

Something similar on the below should do:
