Current setup process overview

There are four setup steps required to start accessing your Customer Journey Analytics data. The following steps are each outlined in greater detail in the following sections:

1. Create an Adobe Console API Project
2. Create and add the JWT arguments to your .Renviron file.
3. Get your authorization token by using the function cja_auth().
4. Get the Data View ID by using the function cja_get_dataviews().

1. Create an Adobe Console API Project

When using JWT authentication, you only need an Adobe Console API project for each organization you are needing to access.

Once you are a developer for a CJA product profile, you can create an API client in the Adobe Developer Console.

1. Navigate to console.adobe.io.
2. Check the organization name in the top right to make sure that you are logged in to the correct company.
3. Click Create new project.
4. Click Add API.
5. Click Customer Journey Analytics, then click Next.
6. Click Generate Keypair.
7. A config.zip file is automatically downloaded to your local machine. Keep this config folder in a secure location, as it contains your only copy of your private key. See steps … for what to do with the private.key file.
8. Click Next.
9. Select the desired product profiles for the service account. Make sure that it contains the right permissions to access the API. Click Save configured API.
10. Back on the project’s home page, click Add to project > API.
11. Click Adobe Experience Platform, then click Next.
12. You already generated a keypair when creating the Adobe Analytics API, so you do not need to create another. Click Next.
13. Select the desired product profiles for the service account. Make sure that it contains the right permissions to access the API. Click Save configured API.
14. Click on “Service Account (JWT)” under “CREDENTIALS” in the left column. Locate the “Download JSON” button on the top right and click it to download the service account JSON file. Alternatively, you can manually create this file by copying and pasting the Client ID, Client Secret (click “Retrieve client secret”), Technical Account ID, and Organization ID into a .json file. Reference ?cja_auth for more information on the variables needed. Using the preconfigured JSON file is the easiest method.
15. Locate the config.zip file that automatically downloaded in step 6. Unzip the file and move the ‘private.zip’ to your desired location. The location of this file will be needed as the value of the CJA_PRIVATE_KEY variable.

2. Set up the .Renviron file

This file is essential to keeping your information secure. It also speeds up analysis by limiting the number of arguments you need to add to every function call.

1. If you do not have an .Renviron file (if you have never heard of this file you almost certainly don’t have one!), then create a new file and save it with the name .Renviron. You can do this from within the RStudio environment and save the file either in your Home directory (which is recommended; click on the Home button in the file navigator in RStudio and save it to that location) or within your project’s working directory. You can also use the “usethis” package to create the file by running the function edit_r_environ(scope = "user")
2. Add the 2 variables, listed below, to the .Renviron file using the file location path for both, the json (auth) file and the private key file. The format of variables in the .Renviron file is straightforward.

## JWT creds ##
CJA_AUTH_FILE=filelocation.json
CJA_PRIVATE_KEY=private.key

After adding these 2 variables to the .Renviron file and saving it, restart your R session (Session > Restart R in RStudio) and reload the package (library(cjar)).

3. Get your access token

The token is actually a lonnnnng alphanumeric string that is the what ultimately enables you to access your data:

1. In the console, enter cja_auth() and press Enter.
2. In the Console window you should see “Successfully authenticated with JWT: access token valid until ….”
3. If you do not see this message then go back and repeat the previous steps to make sure you did not miss something.

4. Get the Data View ID

All data in CJA is located in Data Views, similar to Report Suites in Adobe Analytics. Before pulling data it is essential to locate the data view id you are attempting to pull from.

#Pull a list of available data views

dv <- cja_get_dataviews(expansion = c('name', 'description')) 

#note: see function documentation for all availabe expansion metadata available.

Once you have the data view ID you want then you can begin pulling data using the different functions.
