Hi,<br>
<br>
I use similar approach and problem is (at least I think) that local
DB transaction is already commited when our code runs. It has two
negative effects:<br>
- if remote service call is successful you are not able to write
anything locally as Jorge mentioned<br>
- if remote service call fails local DB record is commited already
and it is hard to implement correct error handling<br>
<br>
So I think User Federation SPI should be extended by exact method
which allows atomic call of backend during user creation or update
before local transaction is commited. I already created issue for it
but not resolved yet <a class="moz-txt-link-freetext" href="https://issues.jboss.org/browse/KEYCLOAK-1075">https://issues.jboss.org/browse/KEYCLOAK-1075</a><br>

<p dir="ltr">Hi,</p>
<p dir="ltr">I think I'm in the right track now. I'm being able to
call the webservice before commit. However, when the user is
sucessfully created by the webservice, I need to update my local
user to add a property with the external user id. How can I do
that in the same transaction?<br>
I'm trying to set the property on the managed delegate user
model, but it has no effect.</p>

You can use "transaction wrapper", which will allow you to
store all the updates to user locally, but send the UPDATE
request to your webservice later at transaction commit time.
You may need to create custom transaction and enlist it with
Keycloak TransactionManager. <br>
<br>
This is what we have for LDAP federation provider right now.
