Hmm, I don't know enough to give you a confident answer yet. However, Ory Kratos does allow for customization of identity schemas, which could potentially be used to store such information. You can find more details on how to customize identity schemas in the [Ory documentation](https://www.ory.sh/docs/kratos/manage-identities/customize-identity-schema#examples).

Based on the provided knowledge sources, Ory Kratos does not directly support storing information about the app from which the user was redirected for login. However, you might be able to achieve this by customizing the identity schema or by using the

request_url

parameter. The

request_url

parameter is the initial URL that was requested from Ory Kratos and can be used to forward information contained in the URL's path or query. This could potentially be used to track the app from which the user was redirected. You can find more about this in the [Ory Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api). For more complex requirements, you might need to customize the identity schema. The identity schema in Ory Kratos is flexible and can be extended with custom fields. You could potentially add a field to store the information about the app from which the user was redirected. More details on how to customize the identity schema can be found in the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/manage-identities/customize-identity-schema#examples). Please note that these are potential solutions and their feasibility would depend on your specific use case and setup.

To store extra information in the identity metadata, you can use the Ory Kratos Admin API. The metadata can be updated using the

PUT /admin/identities/{id}

endpoint. Here is an example of how you might structure your HTTP request:

json PUT /admin/identities/{id} Content-Type: application/json Authorization: Bearer API_KEY  {   "schema_id": "default",   "traits": {     "email": "<mailto:user@example.com|user@example.com>",     "name": "User Name"   },   "state": "active",   "metadata_public": {     "app": "App Name"   } }

In this example,

{id}

should be replaced with the ID of the identity you want to update, and

API_KEY

should be replaced with your actual API key. The

metadata_public

field is being used to store the name of the app. Please note that you need an API Key to call these endpoints. You can read more about [Authorization with API Keys](https://www.ory.sh/docs/concepts/personal-access-token) in the Ory documentation. Also, remember that metadata is not validated using the identity's JSON schema. You must ensure that the metadata you store is valid according to your schema and you must keep the schema up to date to accommodate changes in the data. For more information, refer to the [Ory Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api).

To make an HTTP request after a user signs up, you can use hooks in Ory Kratos. Hooks allow you to run custom logic before and after a Registration Flow. Here is an example of how you might use a hook to make an HTTP request after a user signs up:

javascript const axios = require('axios');  // This is a hypothetical hook function async function afterRegistrationHook(request, response) {   const identityId = request.identity.id;    const updateResponse = await axios.put(`<https://your-kratos-server.com/admin/identities/${identityId}>`, {     schema_id: 'default',     traits: request.identity.traits,     state: 'active',     metadata_public: {       app: 'App Name'     }   }, {     headers: {       'Content-Type': 'application/json',       'Authorization': 'Bearer API_KEY'     }   });    // Handle the response from the update request   if (updateResponse.status === 200) {     console.log('Identity updated successfully');   } else {     console.error('Failed to update identity');   } }  // Use the hook function in your registration flow <http://app.post|app.post>('/auth/registration', (req, res) => {   // Registration logic here...    // Call the hook function after registration   afterRegistrationHook(req, res); });

In this example, replace

'<https://your-kratos-server.com>'

with the URL of your Ory Kratos server and

'Bearer API_KEY'

with your actual API key. Please note that this is a simplified example and you might need to adjust it according to your specific setup and requirements. For more information about hooks, please refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/hooks/configure-hooks).

Sure, you can use Jsonnet to customize the request body of your webhook. Here's an example of how you might structure your Jsonnet code to add the

request_url

to an array in `metadata_public`:

jsonnet function(ctx) {   identity: {     metadata_public: {       request_urls: [ctx.request_url]     }   } }

In this example,

ctx.request_url

is the URL of the request that initiated the flow. This value is automatically provided by Ory Kratos and is available in the

ctx

object. This Jsonnet code will result in a JSON object that looks like this:

json {   "identity": {     "metadata_public": {       "request_urls": ["<http://example.com/auth/registration>"]     }   } }

Please note that this is a simplified example and you might need to adjust it according to your specific setup and requirements. For more information about using Jsonnet with Ory Kratos, please refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/reference/jsonnet).

No, your traits will not be overwritten. The Jsonnet code provided only modifies the

metadata_public

field of the identity. It does not affect the

traits

field. However, if you want to modify the

traits

field in the future, be aware that when you use the

PUT /admin/identities/{{id}}

endpoint, the entire identity object is replaced with the one provided in the request body. So, if you want to keep the existing traits, you need to include them in your request body. For more information, refer to the [Ory Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api).

No, you don't need to include

userId

in this Jsonnet code. The

userId

is not required for adding the

request_url

to the

metadata_public

field of the identity. However, if you want to include the

userId

for some reason, you can access it using

ctx.identity.id

. Here's how you could modify the Jsonnet code to include the `userId`:

jsonnet function(ctx) {   identity: {     id: ctx.identity.id,     metadata_public: {       request_urls: [ctx.request_url]     }   } }

This will add the

userId

to the identity object in the request body. But remember, this is not necessary for adding the

request_url

to the

metadata_public

field. For more information about using Jsonnet with Ory Kratos, please refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/reference/jsonnet).

Your configuration seems mostly correct, but there are a few things to note: 1. The

<http://localhost:4455/ui/registration>

and

<http://localhost:4455/admin/identities/{id}>

should not be enclosed in

< >

. They should be just

<http://localhost:4455/ui/registration>

and

<http://localhost:4455/admin/identities/{id}>

respectively. 2. The

{id}

in the URL

<http://localhost:4455/admin/identities/{id}>

is a placeholder and should be replaced with the actual ID of the identity you want to update. 3. Make sure the file

metadata.jsonnet

exists at the path

/etc/config/kratos/

. Here's the corrected configuration:

yaml registration:   ui_url: <http://localhost:4455/ui/registration>   login_hints: true   enable_legacy_one_step: false   after:     hooks:     - hook: web_hook       config:         url: <http://localhost:4455/admin/identities/{id}>         method: PUT         body: file:///etc/config/kratos/metadata.jsonnet         response:           parse: true

Remember to replace

{id}

with the actual ID of the identity you want to update. For more information, refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/reference/configuration).

No, this will not work. The

url

field in the configuration file does not support dynamic values or expressions like

{ctx.identity.id}

. It should be a static URL. If you want to update the identity after registration, you might need to handle this in your application code. After the user registers, you can use the identity ID returned by Ory Kratos to make a

PUT

request to the

<http://localhost:4455/admin/identities/{id}>

endpoint. For more information, refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/reference/configuration).
