Hi all!

I'm doing some request to an API that has SSL certificate. The output says the follwing:  
**RequestError: unable to verify the first certificate : [https://urlfromtheclient.com](https://urlfromtheclient.com)**  
and also **UNABLE\_TO\_VERIFY\_LEAF\_SIGNATURE**

So, the client sent me the CA certificate which it has "client -- chain -- root) in CRT format. I put that in the following section:

But it doesn't work. I have the same error as above.

Anyone worked this issue before?.

Thanks!

The CA cert should not include the client certificate.

You could try to copy the content _including_ the BEGIN/END CERTIFICATE of the root certificate and save it in a .crt and retry?

ok, and how could i know which is the root part?. The client sent me everything in the same CRT file which include the " **client + chain + root**".

Thanks!
