Authentication Collections are used to define Authentication Parameters that may be utilised repeatedly through the integration configuration. The Authentication Parameter Control Panel offers three configuration fields: Code/Name, Key, and Value. Each Name added then becomes available for selection in the Orchestration Request Manager Control Panel in the Authentication Name dropdown.
Name: Is used to assign a unique reusable ‘Auth Name’ to the specific Authentication Parameter being defined. The list of all the Auth Names that have been defined is reflected in the ‘Auth Name’ dropdown within the Orchestration Manager. These are used when creating a Request to a Receiving System that requires Authentication to be defined, thus the ‘Auth Name’ dropdown is reflected under the ‘Request Manager Control Panel’.
Key + Value: A key-value pair (KVP) is a set of two linked data items: a key, which is a unique identifier for some item of data, and the value, which is either the data that is identified or a pointer to the location of that data. Key-value pairs are frequently used in lookup tables, hash tables, and configuration files.
Note: For signing Amazon AWS requests with Signature Version 4, you can build up the required headers and hashes in the Value as follows:
awsAccessKey, awsSecretKey,awsServiceName,awsRegionName, awsHost, awsContentType, awsXamztarget,awsRequestURI,-2
These values need to be specified in the Public Static Collection. The last value is the timestamp offset- in this case, the server is in UTC-2 so the required value is ‘-2’. See more here.
