Apple and Facebook put an end to a short-lived squabble on Thursday when the iPhone maker restored a key developer certificate for the social media company.

"We have had our Enterprise Certification, which enables our internal employee applications, restored. We are in the process of getting our internal apps up and running," a Facebook spokesman told CNBC in a statement. "To be clear, this didn't have an impact on our consumer-facing services."
