# Reuse an Existing Verification
> Choose between sharing a Sumsub token, sharing a Persona inquiry, or submitting your own encrypted KYC payload.
If you have already verified a customer somewhere else, you do not have to collect
their identity again. Rain accepts a verification you already ran, so the customer
is not asked twice for the same documents.
There are three ways in, and which one you use depends on where the verification
already lives.
## Choose your path
The following table compares the options:
| If you | Use | What you pass on the application |
| :----------------------------------------- | :------------------------------------------------------------------------ | :----------------------------------------------------------------- |
| Already verified the customer with Sumsub | [Sumsub token sharing](/docs/sumsub-token-sharing) | `sumsubShareToken`, a single-use share token |
| Already verified the customer with Persona | [Persona token sharing](/docs/persona-token-sharing) | `personaShareToken`, the ID of an approved inquiry |
| Hold the identity data yourself | [Encrypted KYC submission](/docs/encrypted-kyc-submission) | An encrypted payload, on the standard application endpoint |
| Use another supported vendor | [Connect a vendor in your dashboard](#connect-a-vendor-in-your-dashboard) | The fields the consumer application endpoint lists for that vendor |
Sumsub and Persona token sharing are both available for Consumer Card Programs only.
Sharing a verification does not skip screening. Rain still runs AML, PEP, and
sanctions screening on every party, and still applies its country rules. See
[Verification requirements & screening](/docs/verification-requirements).
## Connect a vendor in your dashboard
Sumsub and Persona each have their own guide, listed in the Choose your path
table. For any other supported vendor, connect it in your dashboard first:
In your developer dashboard, go to the **Config** page and look for the **External integrations** section. The available compliance providers are listed there.
Click the plus icon next to your compliance provider. You'll need to provide some information to enable the integration. For a worked example of what that involves, see [Persona token sharing](/docs/persona-token-sharing), which walks through activating a vendor and supplying its API key.
See the [consumer application endpoint](/reference/applications/create-a-consumer-application-for-a-user) to learn how to use it. The endpoint documentation includes a list of the available compliance providers and the fields you must fill in to share your data.
## What's next
Request a donor key, add Rain as a recipient, and generate a share token.
Activate Persona, configure the inquiry template, and pass the inquiry ID.
