Hi Guys,

I’m having an issue connecting ManyChat to the DeepSeek API.

"This is my first time trying this setup. When I set a new Action Request from ManyChat, it fails to connect to DeepSeek."

I have already confirmed that:

  • My DeepSeek API key is valid

  • The DeepSeek API endpoint is working normally outside ManyChat

  • My DeepSeek account has available balance

  • The issue happens specifically with a new Action Request in ManyChat

I’d like to know:

  • Has anyone experienced the same issue with ManyChat and DeepSeek API?

  • Is there any known limitation related to timeout, headers, or request format in ManyChat Action Request?

  • Is there any way to check logs or debug the failed request inside ManyChat?

Additional details:

  • This is my first time trying this setup, and the request failed

  • I have attached screenshots of the request setup and the connection status in ManyChat

Thanks in advance.

Hey ​@Sam Lin 

I’ve tested it on my end, and indeed, it keeps loading forever. I just shared this with the team so they can look into it.
