# Accept Resources Transfer Request

```http
POST /v1/installations/{installationId}/resource-transfer-requests/{providerClaimId}/accept
```

Finish the transfer process, expects any work required to move the resources from one installation to another on the provider's side is or will be completed successfully. Upon a successful response, the resource in Vercel will be moved to the target installation as well, maintaining its project connection. While the transfer is being completed, no other request to complete the same transfer can be processed. After the transfer has been completed, it cannot be completed again, nor can it be verified.

**Important:** The installation ID in the URL is the target installation ID, not the source one.

## Authentication

**System Authentication**: 
This authentication uses the [OpenID Connect Protocol (OIDC)](https://auth0.com/docs/authenticate/protocols/openid-connect-protocol). Vercel sends a JSON web token (JWT) signed with Vercel’s private key and verifiable using Vercel’s public [JSON Web Key Sets](https://auth0.com/docs/secure/tokens/json-web-tokens/json-web-key-sets) (JWKS) available [here](https://marketplace.vercel.com/.well-known/jwks).
