Troubleshooting OpenAI API issues after payment

Hi everyone,

I recently subscribed and made the payment for OpenAI’s API services. The payment has been successfully deducted from my account, but the API is still not working. I’ve already:

Verified that my API key is active.

Checked my usage limits and billing settings.

Ensured that I’m not exceeding any quotas.

Tried regenerating the API key.

Still, I’m getting errors or no response when I make API requests.

Can anyone from the community or support team guide me on what might be wrong? Is there a delay in activation after payment or any common mistake I might be overlooking?

Thanks in advance!
