# Merchant information data mapping for OpenAI

Understand how merchant information maps to OpenAI fields.

By default, the following fields are mapped from [Custom Fields](/api/projects/custom-fields.md) on the [Store](/urn?urn=ctp%3Aapi%3Atype%3AStore). Each field should be a [CustomFieldStringType](/urn?urn=ctp%3Aapi%3Atype%3ACustomFieldStringType). You can modify the template to source these values from another location or hardcode them.

| OpenAI Field | Related commercetools field | Required | Mapping Logic |
| --- | --- | --- | --- |

| `seller_url` | `store.custom.fields.sellerStoreUrl` | Required | A direct link to the Store or Channel. For example: `https://example.com/store`. |
| `seller_privacy_policy` | `store.custom.fields.sellerPrivacyPolicyUrl` | Required, if `enable_checkout` is `true` | A direct link to the Store or Channel's privacy policy. For example: `https://example.com/privacy`. |
| `seller_tos` | `store.custom.fields.sellerTermsOfServiceUrl` | Required, if `enable_checkout` is `true` | A direct link to the Store or Channel's terms of service. For example: `https://example.com/terms`. |
