Hi, Welcome to the forum.

Have look at the node-red-node-mysql (node) - Node-RED node.
With this node and his samples you should get it working.

Can you describe your setup a bit more -
What sort of RFID sensor do you have?
Is it connected to the Raspberry Pi?
What is the "api rest web service"?
Is MySQL/Mariadb installed on the Raspberry Pi?

Maybe a photo of the setup would help me understand, also a screenshot of your Node-Red flow.
