 After the initial wallet creation which is executed by the portal the process will create the bpn and membership credential.
 
-The portal will request a bpn credential via the endpoint `POST: api/issuer/bpn` which will create a process and a process step. The process will currently fail at step 4 since the issuer wallet is the same as the holder wallet. This will be fixed in the future. For now you can execute the following query to resolve the issue
+The portal will request a bpn credential via the endpoint `POST: api/issuer/bpn` which will create a process and a process step.
+After the process has successfully finished the issuer component will do the callback to the portal with the successfully created bpn credential. The portal will than request the creation of the membership credential via `POST: api/issuer/membership`. The same as for the bpn credential applies for the membership credential.

-**Warning**: Currently the application of the wallet must be set to `catena-x-portal`. This value is not configurable and must be existing in the wallet (see [#226](https://github.com/eclipse-tractusx/ssi-credential-issuer/issues/226)).
