---
Actions are a powerful tool to extend ZITADEL, and you might wonder what use cases actions can be used for.
This page provides a non-exhaustive list of possibilities which is provided by [examples](https://github.com/zitadel/actions/tree/main/examples). If a use case is missing, feel free to contribute an issue or pull request to the repository, thanks in advance 🤗.
## Customize OIDC response
Append claims returned on OIDC requests.
### Triggers
- Complement token
- [Pre Userinfo creation](./complement-token#pre-userinfo-creation-id-token-userinfo-introspection-endpoint)
- [Pre access token creation](./complement-token#pre-access-token-creation)
### Set a hardcoded claim
Extend the claims by a hardcoded value.
Code example
### Set dynamic claim from user metadata
Extend the claims by dynamically reading metadata from a user and sets the picture-claim if idpPicture-metadata value is present.
{props.summary ? props.summary : 'Code example'}
### Set dynamic claim from organization metadata
Extend the claims by dynamically reading metadata from an organization and sets the present metadata.
Code example
### Custom role mapping in claims
Some products require specific role mapping from ZITADEL, no worries we got you covered 😉
Code example
### Custom role mapping including org metadata in claims
There's even a possibility to use the metadata of organizations the user is granted to
Code example
## Customize SAML response
Append attributes returned on SAML requests.
### Triggers
- Complement SAMLResponse
- [Pre SAMLResponse creation](./customize-samlresponse#pre-saml-response-creation)
### Custom role mapping in attributes
Some products require specific role mapping from ZITADEL, no worries we got you covered 😉
Code example
### Set dynamic attribute from organization metadata
Extend the attributes by dynamically reading metadata from an organization and sets the present metadata.
Code example
## Manipulate user
You can automate manual tasks such as assigning default roles during user creation.
### Set email always verified
Useful if you trust the provided information or don't want the users to verify their e-mail addresses.
#### Triggers
- Internal Authentication
- [Pre Creation](/apis/actions/internal-authentication#pre-creation)
- External Authentication
- [Pre Creation](/apis/actions/external-authentication#pre-creation)
Code example
### Assign roles to users
Allows you to assign default roles to a user after the user was created or federated.
#### Triggers
- Internal Authentication
- [Post Creation](/apis/actions/internal-authentication#post-creation)
- External Authentication
- [Post Creation](/apis/actions/external-authentication#post-creation)
Code example
### Add metadata to users
Adding metadata to users allows you to set default metadata on users.
#### Triggers
- Internal Authentication
- [Pre Creation](/apis/actions/internal-authentication#pre-creation)
- [Post Authentication](/apis/actions/internal-authentication#post-authentication)
- External Authentication
- [Pre Creation](/apis/actions/internal-authentication#pre-creation)
- [Post Authentication](/apis/actions/internal-authentication#post-authentication)
Code example
## Use provided fields of identity providers
If you want to ensure that the data of a user are always up to date, you can automatically update user fields during authentication and save time of your customers and your team.
### Trigger
- External Authentication
- [Post Authentication](./external-authentication#post-authentication)
### Fields provided by Okta as OIDC IdP
If you use [Okta as an identity provider](/guides/integrate/identity-providers/okta-oidc), you can improve the onboarding experience of new users by prefilling some basic information during authentication.
Code example
### Fields provided by Gitlab
If you use [Gitlab as an identity provider](/guides/integrate/identity-providers/gitlab), you can improve the onboarding experience of new users by prefilling some basic information during authentication.
Code example
### Fields provided by GitHub
If you use [GitHub as an identity provider](/guides/integrate/identity-providers/github), you can improve the onboarding experience of new users by prefilling some basic information during authentication.
Code example
### Claims provided by a generic OIDC identity provider
If you use a [generic OIDC identity provider](/guides/integrate/identity-providers/migrate#migrate-generic-oidc-provider), you can improve the onboarding experience of new users by prefilling some basic information during authentication.
Code example
### Attributes provided by Okta as SAML IDP
If you use [Okta as an identity provider](/guides/integrate/identity-providers/okta_saml#add-attribute-statements), you can improve the onboarding experience of new users by prefilling some basic information during authentication.
Code example
### Attributes provided by Microsoft Entra as SAML IDP
If you use [Microsoft Entra as SAML identity provider](/guides/integrate/identity-providers/azure-ad-saml), you can improve the onboarding experience of new users by prefilling some basic information during authentication.
Code example
### Attributes provided by a generic SAML identity provider
If you use a [SAML identity provider like mocksaml](/guides/integrate/identity-providers/mocksaml), you can improve the onboarding experience of new users by prefilling some basic information during authentication.
Code example
## Context-aware execution
Based on the context, the execution path of an action can change. ZITADEL allows complex execution paths, of course. 😎
### Based on auth request information
Execution paths might change based on the application initiating the authentication.
#### Triggers
- Internal Authentication
- [Pre Creation](/apis/actions/internal-authentication#pre-creation)
- [Post Creation](/apis/actions/internal-authentication#post-creation)
- [Post Authentication](/apis/actions/internal-authentication#post-authentication)
- External Authentication
- [Pre Creation](/apis/actions/external-authentication#pre-creation)
- [Post Creation](/apis/actions/external-authentication#post-creation)
- [Post Authentication](/apis/actions/external-authentication#post-authentication)
Code example
This example uses [zitadel's log module](/apis/actions/modules#log)
### Check authentication error
Your action can also check for errors during the login process.
#### Triggers
- Internal Authentication
- [Post Authentication](/apis/actions/internal-authentication#post-authentication)
- External Authentication
- [Post Authentication](/apis/actions/external-authentication#post-authentication)
Code example
This example uses [zitadel's log module](/apis/actions/modules#log)
### Throw an error
Allows you to limit the user interaction. The error thrown will be shown to the user if the action is not [allowed to fail](/concepts/features/actions#how-it-works).
