Is a Texas sales tax permit the same as a resale certificate?

Excuse me, I've been doing some research on sales tax permits and resale certificates, and I've come across a question that's been puzzling me. Is a Texas sales tax permit essentially the same thing as a resale certificate? I understand that both documents involve taxation, but I'm unsure if they serve the same purpose or have different uses. Could you please clarify the difference between the two for me? I'd appreciate any insight you could offer.
