The Professional Way to Collect Client Credentials

"Hey, I need your HeyGen API key to set up the integration."
"Um, how do I get that? Can you just log in for me?"
"Well, I'd need you to generate it and then send it securely..."
"This sounds complicated. Can we do this later?"

Sound familiar? What if there was a better way?

Imagine sending your client a simple, secure form where they can safely connect their HeyGen account in 30 seconds. No screenshots of API keys, no insecure email exchanges, no frustrated clients. They click, authenticate, and you're instantly ready to build their video automation solution.

That's exactly what Creddy.me does. Instead of spending 20 minutes explaining API key generation to each client, you spend 2 minutes sending them a secure credential collection form. They're happy, you're efficient, and everyone gets back to building cool stuff.
