WEBSVC Custom Authentication Configuration

Hello

In our project we are trying to connect an API with below token request defined by the provider:

we have defined below contents in configuration:

Header

Authorization: (empty)

Body

username

password

pin

Authentication

Cert File: (empty)

Private Key: (empty)

we also tested with only body parameters by deleting all other parameters inside Header and Authorization.

We could achieve connection.

We tested with curl to connect API:

curl -X POST "">accesscontrol.xyz.com:2626/.../Token" -H "Content-Type: application/json" -d "{\"username\":\"user\",\"password\":\"1234\",\"pin\":\"1234\"}"

this command returns SSL certificate error. (SSL certificate is already imported to Trusted Root.)

curl -k -X POST "">accesscontrol.xyz.com:2626/.../Token" -H "Content-Type: application/json" -d "{\"username\":\"user\",\"password\":\"1234\",\"pin\":\"1234\"}"

this command successfully returns the token. since SSL is ignored.(with including -k in the command)

I thought the reason why WEBSVC does not get token is similarly the SSL error...

My question:

How can I configure Custom Authentication with ignoring SSL certificate?

Or how can I configure Cert File field in authentication to make it recognize the certificate. I could not find any information in documentation to configure this.

On the other hand below is the logs for OI Server:

Instead of SSL, do I have misconfiguration for Authentication settings?

Any suggestions welcome.

thanks in advance
