Adobe Target Admin API error code:403003, API key is invalid

Here's a more detailed step by step how to document on generating the API token.  Please try these steps to check if your issue is resolved .

1 - Generate private key and public certificate per the following documentation: https://www.adobe.io/apis/cloudplatform/console/authentication/createcert.html

On a Mac, the following commands are built into terminal.

On a PC, you will need to download Cygwin (or other tool of personal preference) and run it from command line.   Here are the steps to download and install Cygwin:

1. Browse to: https://cygwin.com/install.html
2. Download and run setup-x86_64.exe

Notes:  Your home directory will be: C:\cygwin64\home\WINDOWSUSER
You can search for and install additional packages during the install phase. I recommend installing everything related to "curl" and "ssh"
Here is the command to run:

$ openssl req -nodes -text -x509 -newkey rsa:2048 -keyout secret.pem -out certificate.pem -days 356

Note:  It will ask you several questions that you need to fill out to generate the certificate, see screenshot below:After the files have been created, you will convert the secret.key to secret.pem using the following command:

$ openssl pkcs8 -topk8 -inform PEM -outform DER -in secret.pem  -nocrypt > secret.key

Here are the files that are created on your file system (you may move these files to another location on your machine at this point for organization):Notes:  The files will be generated in your home directory: C:\cygwin64\home\WINDOWSUSER

2 - Create integration within the Adobe IO console:

Go to https://console.adobe.io/

Select company

click "New Integration" button

Select "Access an API" option, then click "continue"
Select Adobe Solution (currently only available for Target)

Note: User must be a user of the Experience Cloud AND have access to that solution.Select "New integration" and click "Continue"Fill out integration formDrag "certificate.pem" from file system into form to uploadOnce the file is uploaded, click "Create integration" button - see screenshot: fileuploaded_createintWhen processing is complete, click "continue to integration details"Success!  You have now created an integration

3 - Generate JSON Web Token (JWT):

In the Integration UI, click on the JWT tab, paste in private key, click Generate JWT button - see screenshot: generating JWT - inputOnce it is generated, you will see the JWT and a sample CURL command

Click on "copy" icon below "Generated JWT"4 - Exchange JWT for Bearer Access Token:

Note: If you run this in terminal on a Mac, the response seems to get truncated.  Instead, use Postman

Download and install free API tool named "Postman" (available on Mac, Windows, or Linux):  https://www.getpostman.com/

Import this api call into Postman by copying the code below into a text file on your computer with a .json extension:

example filename: exchangeJwt.json

Import file into Postman by going to file > Import:  you can drag and drop the .json file here or browse for the fileThis will create a "collection" in Postman on the left-hand side, with one API call in it named "Exchange JWT for Bearer token"Click on the API call "Exchange JWT for Bearer token"

In the main section of the UI this is what you will seeNote: as highlighted in red above, I'm in the "Body" tab.  If you are in another tab, you will not see the three pieces of information that are required

Info Needed:

• client_id: get from Integration overview page
• client_secret: generate on Integration overview page
• jwt_token: paste in generated JWT token that you copied in previous step

Click "send"

The bearer token is retrieved, which will be used to make API calls

The access_token is what will be used as part of the API calls you intend to run
