 Issuing a credential from the Faber agent to Alice’s agent is done with another API call. In the Faber browser tab, scroll down to the **`POST /issue-credential/send`** and get ready to (but don’t yet) execute the request. Before execution, you need to find some other data to complete the JSON. 
 
-First, scroll back up to the **`GET /connections`** API endpoint and execute it. From the result, find the the `connection_id` and copy the value. A little trickier to find is the `credential_definition_id`. Go back to the terminal where you started the Faber agent, and scroll back until you see the text `#3/4 Create a new schema/cred def on the ledger` and then just below that `Cred def Id:`. Copy the text following that label. Another way to get the `credential_definition_id` is to find it by searching the Indy network transactions posted to the ledger browser app. That works well if you are running locally by clicking the `Domain` link and using the search feature. However, that approach is harder to do when running in the browser, because there are many credential definitions on that ledger instance.

 Now we need put into the JSON the data values for the credential. Copy and paste the following between the `attributes` square brackets. Feel free to change the attribute values (but neither the labels nor the names) as you see fit:
