To pass a

transient_payload

to an after-registration webhook when using a social SSO sign-up method, you can follow these steps: 1. First, ensure that you have configured a webhook for the registration flow, specifically for the social sign-in (OIDC) method. This can be done using the Ory CLI or by modifying your configuration file. 2. When implementing your custom UI for social sign-in, you can include the

transient_payload

in the registration flow. This payload will be forwarded to any configured webhooks without being persisted by Ory. 3. To include the

transient_payload

, you need to add it to the request body when submitting the registration flow. Here's an example of how you can structure your request:

json {   "method": "oidc",   "traits": {     "email": "<mailto:user@example.com|user@example.com>"   },   "transient_payload": {     "consents": "newsletter,usage_stats"   } }

4. When making the API call to complete the registration, include this payload in your request body. The

transient_payload

will be forwarded to your configured webhook. It's important to note that the exact implementation may vary depending on your specific setup and the social sign-in provider you're using. The

transient_payload

feature is generally available for various registration methods, including social sign-in. For more detailed information on configuring webhooks and using the

transient_payload

, you can refer to the following resources: - [Ory Actions Webhooks Guide](https://www.ory.sh/docs/guides/integrate-with-ory-cloud-through-webhooks) - [Ory Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api#tag/frontend/operation/updateRegistrationFlow) Remember to adjust your webhook configuration to handle the

transient_payload

data appropriately on your server-side logic.

To add a

transient_payload

field when using a social SSO button rendered with Ory Elements, you'll need to customize the registration flow. However, it's important to note that Ory Elements doesn't directly provide a way to add custom fields to the social SSO buttons it renders. Instead, you can approach this by intercepting the registration flow before it's submitted. Here's a general approach you can take: 1. First, render your social SSO buttons using Ory Elements as usual. 2. Before the user clicks on a social SSO button, you can store the

transient_payload

data in a client-side storage mechanism (like localStorage or sessionStorage). 3. After the user completes the social SSO flow and is redirected back to your application, you'll need to intercept the registration flow before it's submitted. 4. At this point, you can retrieve the stored

transient_payload

data and add it to the registration flow submission. Here's a conceptual example of how you might implement this:

javascript // Store transient payload before social SSO const transientPayload = { consents: "newsletter,usage_stats" }; sessionStorage.setItem('transientPayload', JSON.stringify(transientPayload));  // After social SSO redirect, intercept the registration flow frontend.getRegistrationFlow({ id: flowId })   .then((flow) => {     const storedPayload = JSON.parse(sessionStorage.getItem('transientPayload'));          const updatedBody = {       ...flow,       transient_payload: storedPayload     };      return frontend.updateRegistrationFlow({       flow: flow.id,       updateRegistrationFlowBody: updatedBody     });   })   .then(() => {     // Registration complete     sessionStorage.removeItem('transientPayload'); // Clean up   })   .catch((error) => {     // Handle errors   });

This approach allows you to add the

transient_payload

to the registration flow even when using Ory Elements for rendering the social SSO buttons. However, it's important to note that this is a client-side solution and may not be suitable for all use cases, especially those requiring high security. For more information on working with registration flows and the Ory API, you can refer to the [Ory Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api#tag/frontend/operation/updateRegistrationFlow). Remember to adjust this approach based on your specific implementation and security requirements. If you need a more secure way to handle this, you might want to consider implementing a custom UI instead of using Ory Elements, which would give you more control over the entire process.
