Updating SMTP Client Configuration by using Postman failed

[eric.yang]

Hi there,

I tried to update smtp configuration by using Postman but failed with error 400 Bad Request. Is there anything wrong?

Thanks.

Hi eric, what product/API?

[dstaudt]

It appears that SMTP client management support appears only as of CUC v14SU2 - are you perhaps using an earlier version?

[eric.yang]

Unity Connection v14SU3

Hi 

Without knowing the CUPI APi. Two points: In the screenshot you provided, it looks like theres a comma missing after the smtpUsername-value - the paylood should look like this:

{
    "smtpSmartHost": "smtp.sendgrid.net",
     "isClientSecure": "true",
     "smtpPort": "587",
     "isAuthEnabled": "false",
     "smtpUsername" : "apikey", 
     "smtpPassword" : "yourpassword"
}

If the comma is there and it's not working, I would give it a try and send the true/false values as booleans instead of strings:

{
    "smtpSmartHost": "smtp.sendgrid.net",
     "isClientSecure": true,
     "smtpPort": "587",
     "isAuthEnabled": false,
     "smtpUsername" : "apikey", 
     "smtpPassword" : "yourpassword"
}

Yes, a coma was missing. The SMTP configuration in Unity was updated with 200 OK. However, smtp port is 25 instead of 587 on web GUI. I have to manually change it on Unity.

Maybe like my example with the booleans, try to specify the port as integer instead of a string:

{
    "smtpSmartHost": "smtp.sendgrid.net",
     "isClientSecure": true,
     "smtpPort": 587,
     "isAuthEnabled": false,
     "smtpUsername" : "apikey", 
     "smtpPassword" : "yourpassword"
}

Testing with CUC v14SU3, this seems to work for me:

I do note that the response body here is XML while the Accept/Content-Type are requested/indicated as application/json - it may be more consistent to specify XML.

Thanks everyone for the help. Everything is good now.
