I also , added provider_id manually in database at payment_provider table but it give me following error

{ "type": "not_found", "message": "Could not find a payment provider with id: stripe" }

Answer 1

when you run your backend you should preserve symlinks for your backend to start with the linked pluging you can acheave that by this command :

npm run dev --  -- --preserve-symlinks

or you can add it to your package.json scripts:

"dev:link": "cross-env npm run dev --  -- --preserve-symlinks"

and run it with :

yarn dev:link

Note: dont forget to add your plugin to your medusa-config.js
