Receive payments in virtual currencies

1. Create a PaymentIntent

Use the Create PaymentIntent endpoint and send a payload with at least the required parameters.

📘

Note

This is a protected endpoint and the usage of your API Key is required.

By default, Coinify provides a BTC quote for the PaymentIntent. See how to preselect a different cryptocurrency.

2. Redirect your customer or Host your own Payment Window

Coinify Hosted Payment Window

Coinify provides a hosted checkout user interface which enables your customer to easily send the requested amount to the correct address and also choose from a variety of virtual currencies.

The URL to the Coinify hosted checkout user interface is returned in the successful response of the Create a PaymentIntent endpoint.

📘

Note

Use the GET HTTP verb to redirect your customer.

Self-hosted Payment Window

The PaymentIntent resource provides you with all the necessary data to build your own Payment Window around it and provide the UX/UI that is aligned with your brand.

After a successful creation of a PaymentIntent, call the Read PaymentIntent endpoint to retrieve the PaymentIntent resource and fetch relevant payment information from the latest quote. All the created quotes can be found in the quotes object.

3. Expect a webhook notification

Coinify sends a callback notification to a webhook URL you provided once a PaymentIntent has been completed or failed.

If you are building a self-hosted payment window, you need to inform the customer about a successful or failed payment. The state and stateReason of a PaymentIntent are provided in the webhook events.

For more information on how to set up a webhook URL with Coinify and see the structure of the notifications read the Webhooks guide.

Validate the signature

Coinify includes a signature in the Header of each webhook notification request.
For more information on validating the signatures, read the Webhooks guide.

❗️

Important

Never accept a payload before validating that the signature is correct.

Completed/Failed states

Based on the state received in a webhook notification you can determine whether the PaymentIntent was successful or not and provide or reject the service/product to your end-user accordingly.

Once you receive a completed notification that contains the correct signature, the PaymentIntent was successful and your merchant account has been credited.

Once you receive a failed notification that contains the correct signature, the PaymentIntent was not successful and your merchant account has not been credited.
