Payment Provider

Through a payment provider a user is able to obtain points. This chapter explains more in detail how this process works. If a user of your API wants to obtain points he has to use a configured payment provider. To start the payment process your app has to send a POST request to the /consumer/transaction/prepare/stripe endpoint (in this example we use stripe as provider) with the following payload:

"planId": 1,
"returnUrl": "{transaction_id}"

The planId is the id of a plan which was configured at the backend. The return url is the url of your app where the user returns after the payment was completed. If everything is valid the endpoint returns an approval url of the payment provider:

"approvalUrl": ""

Your app has to simply redirect the user to this approval url. Then the user authenticates at the payment provider and approves the payment. Then the user gets redirected to the /consumer/transaction/execute/{transaction_id} endpoint where Fusio checks whether the payment was accepted. If yes Fusio credits the amount of points to the user.

Then it redirects the user to the return url which was provided in the initial prepare call. You app can then lookup the status of the transaction and display a fitting message.


It is also easy to implement a custom payment provider. It is important that the provider supports a redirect based flow. It is currently not possible to simply enter the credit card number. To create a new payment provider you need to create a class which implements the Fusio\Engine\Payment\ProviderInterface
