If you are only using the ThingSpeak REST API and/or accessing the website, ports 80 and 443 need to be opened.

If you are using MQTT publish/subscribe, ports 1883 and 8883 also need to be opened.

If you are still deciding between using REST and MQTT, a useful resource for selecting one over the other for particular scenarios is available at:
