IP Address Forwarding

Some payment service providers will require the IP address of the buyer to be sent to them for anti fraud purposes.

​

Embed

By default, when using Embed the IP address of the buyer will be passed to the payment service automatically by us where needed.

​

Server-to-server

When you are creating transactions on behalf of a buyer via your own server without the use of Embed, you can pass the IP address of the buyer to us via the X-Forwarded-For header.

curl --header "X-Forwarded-For: 192.168.0.2" https://api.example.gr4vy.app/...

We will automatically accept this header and pass it to the payment service where needed.
