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


Level 3

I am trying to use the Adobe Target Admin API and I have encountered the following error while using any of the admin API request:


    "error_code": "403003",

    "message": "Api Key is invalid"


Note: The API key that I am using in any admin API request is same as the API key I used to generate JWT and access token using JWT.

Steps followed:

Step 1: Integration of Target API with public certificate in Adobe I/O console - Successful

Step 2: Generate JWT signed with private key - Successful

Step 3: Exchange JWT with access token - Successful

Step 4: Use the access token generated in Step-3 in an admin API request - Unsuccessful (Error Message - "Api key is Invalid")

Is it because of the fourth parameter in JWT payload from API Integration is different from that provided in sample code of Adobe I/O Authentication document? i.e.

Parameter in Sample code: '': true

Parameter in JWT payload from API: "": true,

JWT Payload:


    "exp": 1524821003,

    "iss": "....@AdobeOrg",

    "sub": "",

   "": true,

    "aud": ""

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:

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:
  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:User-added imageAfter 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):User-added imageNotes:  The files will be generated in your home directory: C:\cygwin64\home\WINDOWSUSER

2 - Create integration within the Adobe IO console:

Go to

Select company

click "New Integration" buttonUser-added image

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

Note: User must be a user of the Experience Cloud AND have access to that solution.User-added imageSelect "New integration" and click "Continue"User-added imageFill out integration formUser-added imageDrag "certificate.pem" from file system into form to uploadUser-added imageOnce the file is uploaded, click "Create integration" button - see screenshot: fileuploaded_createintUser-added imageWhen processing is complete, click "continue to integration details"User-added imageSuccess!  You have now created an integrationUser-added image

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 - inputUser-added imageOnce it is generated, you will see the JWT and a sample CURL command

Click on "copy" icon below "Generated JWT"User-added image4 - 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):

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

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

Hi There, Thanks for the reply. The error that I am facing is on the 5th step (in the flow mentioned). I have successfully completed first four steps and have successfully generated an Access Token with (X) client secret and (Y) client ID (or API ID). When I am using the access token generated to access an API (i.e. step 5) I am getting an error of "API Key is invalid", I am using the same API Key (Client ID) that i used to generate Access token.



kartikbhatia If you still face issues generating the token, then you will need to submit a support ticket via this link . There is a dedicated team that handle issues with adobe io and they should be able to assist you further on this.
