How to use Secure Credentials Store for passing the credentials in API?

Question

Hi, 
 I have one smart service that integrates with the external system. 
 I am using the Third Party Credential Store in Appian Administrator console and created with Filed Name and value. 
 I need to provide Third Party Credentials while consuming an API. 
 So may I know the process or how to use the secure credentials store for passing the credentials? 
 and I already used a!scsField() so how this function exactly works? 
 Kindly provide your suggestions. 
 
 Thanks In Advance 
 Aswini

Hi Aswini, 
 
If your smart service has secure credential store as parameter pass the secure credential store name that should be sufficient and make sure to populate the plugin field in SCS with the plugin you are using

Hi @Aswini adding to the above comment. 
 Also if it's a custom plugin then please make sure, you add this plugin under Plug-ins List of the Third-Party Credentials you are referring to obtain the credentials under Admin Console otherwise you may get an exception saying, your plugin is not authorized to access Secured Credentials . 
 Hope this will help.
