What is the best way to implement in-app purchases without a third-party service?

• laravel-in-app-purchases

  1 283 6.7 PHP

  Validate products and subscription receipts. Handle subscription lifecycle.

This part is necessary if you offer subscriptions and you have to keep track of the subscription status. It's a bit more difficult to build, so I suggest you look for a library that can handle it for you (examples Laravel/NodeJS). That said, it is not impossible to implement it yourself.

• app-store-server-api

  1 188 7.2 TypeScript

  A Node.js client for the App Store Server API

This part is necessary if you offer subscriptions and you have to keep track of the subscription status. It's a bit more difficult to build, so I suggest you look for a library that can handle it for you (examples Laravel/NodeJS). That said, it is not impossible to implement it yourself.

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• php-jwt

  PHP package for JWT

  

This depends on the library you end up downloading for the platform of your choosing. Some of the parts I explained above will be handled by the library for example in my case I decoded signedTransactionInfo using firebase/php-jwt. This has the added benefit of always checking the validity of the signature which was omitted in the manual method.

• jwt-decode

  4 3,073 8.7 TypeScript

  Decode JWT tokens; useful for browser applications.

  

Now I should mention it's NOT recommended to do this manually. There are great libraries that can help (examples PHP/NodeJS). For the sake of completeness here's how you do it.
