OIC - Import (Replace) a Lookup | Update an existing OIC Lookup based on base64 encoded CSV file as rest feed

Usecase: We have a requiremwnt that we will create a reusable integration which will take input as lookup name and base64 encoded csv content and update or replace the OIC lookup based on that CSV file.

Logic steps:

1. Create 2 connections
1. Rest trigger connection
2. OIC Rest invoke connection for oic lookup update rest api call
2. Create an app driven orchestration style
3. Configure rest trigger with the following:
1.  Request: 
1. Base64 encoded csv content
2. Lookup name
2. Response:
1. jobStatus
2. Exception code, reasona and details
4. Assign globals 
1. Content: decodeBase64ToReference(base64StreamRef)
2. Exception code, reason, details and result variables
5. Take a scope and drag and drop created oic rest invoke connection and configure to update the lookup
1. Api: /ic/api/integration/v1/lookups/archive
2. Verb: Put
3. Request: Multipart/form-data
4. Response: binary , other media type: application/json; charset=utf-8
6. Map the following:
1. AttatchmentReference : content
2. contentType: applocation/octet-stream
3. partName: lookupname + ".csv"
4. fileInputHtmlFieldName : file
7. Go to default fault handler and assign the scope fault details and result as "UPDATE_ERROR"
8. Assign the final response.

Rest trigger Request json:

{

"base64StreamRef":"ref",

"lookupName":""

}

Rest trigger Response Json:

{

"jobStatus":"",

"jobMessage":"",

"exceptionCode":"",

"exceptionReason":"",

"exceptionDetails":""

}

Detailed steps with screenshots:

Create OIC Rest connection:

Create a rest trigger connection:

Create an app driven integration and configure the Rest trigger

Take a scope and configure OIC rest invoke adapter to update lookup

Assign global 

Content as decodebase64ToReference

Different exception details variables

Map the required details to update the lookup

Map the exception details in default handler

Do the final response mapping.

Add tracking and activate.

Create a lookup

Export the lookup file

Update the lookup file.

Test the file

We can see that the lookup has been updated.

Test with wrong file details and see the exception details in formatted manner.

Note: this is to update or replace existing lookup. To import new lookup file, use rest verb as post instead of put.
