To include the invoice PDF in the email, select the **Include Invoice PDF** check box in the **Edit notification** dialog from the Zuora UI. See [Create and Edit Notifications](https://knowledgecenter.zuora.com/CF_Users_and_Administrators/Notifications/C_Create_Notifications#section_2) for more information. - Zuora sends the email messages based on the email template you set. You can set the email template to use in the **Delivery Options** panel of the **Edit notification** dialog from the Zuora UI. By default, the **Invoice Posted Default Email Template** template is used. See [Create and Edit Email Templates](https://knowledgecenter.zuora.com/CF_Users_and_Administrators/Notifications/Create_Email_Templates) for more information. - The invoices are sent only to the work email addresses or personal email addresses of the Bill To contact if the following conditions are all met: * The `useEmailTemplateSetting` field is set to `false`. * The email addresses are not specified in the `emailAddresses` field. Reference: https://zuora.ferndocs.com/developers/api-reference/zuora-api/billing-documents/invoices/post-email-invoice ## Authentication - `Authorization` header (bearer token, required) — Use `Bearer {{token}}` in the `Authorization` header for authentication. ## Servers - `https://rest.test.zuora.com` (US Developer & Central Sandbox (incl. Test Drive), default) - `https://rest.sandbox.na.zuora.com` (US API Sandbox Cloud 1) - `https://rest.apisandbox.zuora.com` (US API Sandbox Cloud 2) - `https://rest.na.zuora.com` (US Production Cloud 1) - `https://rest.zuora.com` (US Production Cloud 2) - `https://rest.test.eu.zuora.com` (EU Developer & Central Sandbox) - `https://rest.sandbox.eu.zuora.com` (EU API Sandbox) - `https://rest.eu.zuora.com` (EU Production) - `https://rest.test.ap.zuora.com` (APAC Developer & Central Sandbox) - `https://rest.ap.zuora.com` (APAC Production) ## Request ### Path parameters - `invoiceKey` (string, required) — The ID or number of the invoice. For example, 2c92c8955bd63cc1015bd7c151af02ab or INV-0000001. ### Headers - `Idempotency-Key` (string, optional) — Specify a unique idempotency key if you want to perform an idempotent POST or PATCH request. Do not use this header in other request types. With this header specified, the Zuora server can identify subsequent retries of the same request using this value, which prevents the same operation from being performed multiple times by accident. - `Accept-Encoding` (string, optional) — Include the `Accept-Encoding: gzip` header to compress responses as a gzipped file. It can significantly reduce the bandwidth required for a response. If specified, Zuora automatically compresses responses that contain over 1000 bytes of data, and the response contains a `Content-Encoding` header with the compression algorithm so that your client can decompress it. - `Content-Encoding` (string, optional) — Include the `Content-Encoding: gzip` header to compress a request. With this header specified, you should upload a gzipped file for the request payload instead of sending the JSON payload. - `Zuora-Track-Id` (string, optional) — A custom identifier for tracing the API call. If you set a value for this header, Zuora returns the same value in the response headers. This header enables you to associate your system process identifiers with Zuora API calls, to assist with troubleshooting in the event of an issue. The value of this field must use the US-ASCII character set and must not include any of the following characters: colon (`:`), semicolon (`;`), double quote (`"`), and quote (`'`). - `Zuora-Entity-Ids` (string, optional) — An entity ID. If you have [Zuora Multi-entity](https://knowledgecenter.zuora.com/BB_Introducing_Z_Business/Multi-entity) enabled and the OAuth token is valid for more than one entity, you must use this header to specify which entity to perform the operation in. If the OAuth token is only valid for a single entity, or you do not have Zuora Multi-entity enabled, you should not set this header. - `Zuora-Org-Ids` (string, optional) — Comma separated IDs. If you have Zuora Multi-Org enabled, you can use this header to specify which orgs to perform the operation in. If you do not have Zuora Multi-Org enabled, you should not set this header. The IDs must be a sub-set of the user's accessible orgs. If you specify an org that the user does not have access to, the operation fails. This header is important in Multi-Org (MO) setups because it defines the organization context under which the API should operate—mainly used for read access or data visibility filtering. If the header is not set, the operation is performed in scope of the user's accessible orgs. - `Zuora-Version` (string, optional) — The minor API version. For a list of available minor versions, see [API upgrades](https://developer.zuora.com/v1-api-reference/api-upgrades/). ### Body (application/json) This endpoint expects a PostInvoiceEmailRequestType. - `emailAddresses` (string, optional) — The valid email addresses you want to email an invoice to. Use commas to separate email addresses. **Note:** This field is only applicable if you set the `useEmailTemplateSetting` field to `false`. - `includeAdditionalEmailAddresses` (boolean, optional, default: false) — Whether to send an invoice to the additional email addresses of the invoice account. You can set the additional email addresses in the **Additional Email Addresses** field on the account detail page from the Zuora UI. See [Create a Customer Account](https://knowledgecenter.zuora.com/BC_Subscription_Management/Customer_Accounts/B_Create_a_Customer_Account#section_2) for more information. - `useEmailTemplateSetting` (boolean, optional, default: false) — Indicates whether to email an invoice based on the email template setting. If you set this field to `true`, the invoice is sent to the email addresses specified in the **To Email** field of the email template. The email template is the one you set in the **Delivery Options** panel of the **Edit notification** dialog from the Zuora UI. See [Edit Email Templates](https://knowledgecenter.zuora.com/CF_Users_and_Administrators/Notifications/Create_Email_Templates) for more information about how to edit the **To Email** field in the email template. ## Response ### 200 OK - `processId` (string, optional) — The ID of the process that handles the operation. - `reasons` (list of CommonResponseReasonsItems, optional) — The container of the error code and message.
