It carries the verified SDK shapes and the rules you cannot get wrong. > Authenticate every request with `Authorization: Bearer `. A workspace has several environments and each has its own keys, which are plain `pk_` strings with no environment prefix. Start with Test. > Send with `client.send.message`, the default import of the v7 Node SDK. Reference a template by its `nt_` id or its alias. > A send accepts a bare Elemental element list, but storing content on a template requires the top-level elements wrapped in a channel element. > Templates and journeys can be built in the Courier app or created through the API. Either way they live in the workspace and are referenced by ID when you send. > The hosted MCP server is https://mcp.courier.com. For a briefing on what Courier is and when to use it, read https://www.courier.com/llms.txt. > Prefer the Guides tab for how-do-I questions and the Docs tab for how-does-it-behave questions. The API reference lives under /api-reference. # Elemental divider element > Render a horizontal rule between content sections, with color and spacing. export const Doc = ({href, children, name, bare}) => { const label = children || name || href; if (bare) { return {label}; } return {label} DOC ; }; The divider element renders a horizontal rule between elements. Use it to separate content sections. The type value is `"divider"`. **When to use:** * Separate distinct sections of content * Create visual breaks between related items * Improve readability in long notifications * Organize grouped content visually **Basic example** ```json Elemental theme={null} { "type": "divider", "color": "#800080" } ``` ```javascript Node.js highlight={9-12} theme={null} const { requestId } = await client.send.message({ message: { to: { email: "sarah@acme-corp.com", }, content: { version: "2022-01-01", elements: [ { type: "divider", color: "#800080", }, ], }, }, }); ``` ```python Python highlight={9-12} theme={null} response = client.send.message( message={ "to": { "email": "sarah@acme-corp.com", }, "content": { "version": "2022-01-01", "elements": [ { "type": "divider", "color": "#800080", }, ], }, }, ) ``` ```bash cURL highlight={12-15} theme={null} curl -X POST https://api.courier.com/send \ -H "Authorization: Bearer $COURIER_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "message": { "to": { "email": "sarah@acme-corp.com" }, "content": { "version": "2022-01-01", "elements": [ { "type": "divider", "color": "#800080" } ] } } }' ``` ```ruby Ruby highlight={9-12} theme={null} response = courier.send_.message( message: { to: { email: "sarah@acme-corp.com" }, content: { version: "2022-01-01", elements: [ { type: "divider", color: "#800080" } ] } } ) ``` ```go Go highlight={5-8} theme={null} // Elemental nodes carry no typed content fields, so pass the document as raw JSON. content := param.Override[shared.ElementalContentParam](json.RawMessage(`{ "version": "2022-01-01", "elements": [ { "type": "divider", "color": "#800080" } ] }`)) response, err := client.Send.Message(context.TODO(), courier.SendMessageParams{ Message: courier.SendMessageParamsMessage{ To: courier.SendMessageParamsMessageToUnion{ OfUserRecipient: &shared.UserRecipientParam{ Email: courier.String("sarah@acme-corp.com"), }, }, Content: courier.SendMessageParamsMessageContentUnion{OfElementalContent: &content}, }, }) ``` ```java Java highlight={7-9} theme={null} SendMessageParams params = SendMessageParams.builder() .message(SendMessageParams.Message.builder() .to(JsonValue.from(java.util.Map.of("email", "sarah@acme-corp.com"))) .content(JsonValue.from(java.util.Map.of( "version", "2022-01-01", "elements", java.util.List.of( java.util.Map.of( "type", "divider", "color", "#800080"))))) .build()) .build(); SendMessageResponse response = client.send().message(params); ``` ```php PHP highlight={9-12} theme={null} $response = $client->send->message( message: [ 'to' => [ 'email' => 'sarah@acme-corp.com', ], 'content' => [ 'version' => '2022-01-01', 'elements' => [ [ 'type' => 'divider', 'color' => '#800080', ], ], ], ], ); ``` ```csharp C# highlight={12-15} theme={null} // Elemental nodes expose no typed content fields, so build the document from raw JSON.

Any valid CSS color value (e.g., `"#e0e0e0"`, `"rgb(224, 224, 224)"`, `"gray"`). Defaults to a standard gray. Border width in pixels for the divider line (e.g., `"1px"`, `"2px"`). Padding around the divider. Any valid CSS padding value (e.g., `"10px"`, `"20px 10px"`). An array of channel names. The divider renders only for the listed channels. See Control flow. **Examples and variants** **Basic divider** Simple divider with default styling: ```json theme={null} { "type": "divider" } ``` **Styled divider** Divider with custom color: ```json theme={null} { "type": "divider", "color": "#800080" } ``` **Thick divider** Divider with custom width: ```json theme={null} { "type": "divider", "color": "#007bff", "border_width": "3px" } ``` **Divider with padding** Divider with spacing: ```json theme={null} { "type": "divider", "color": "#e0e0e0", "padding": "20px 0" } ``` **Section separator** Using dividers to separate content sections: ```json theme={null} { "version": "2022-01-01", "elements": [ { "type": "text", "content": "Order Summary", "text_style": "h2" }, { "type": "text", "content": "Item 1: $29.99" }, { "type": "text", "content": "Item 2: $49.99" }, { "type": "divider", "color": "#cccccc" }, { "type": "text", "content": "Total: $79.98", "bold": true } ] } ``` **Channel support** * **Email**: ✅ Full support with styling * **Push**: ⚠️ Limited support (may render as plain text or be ignored) * **SMS**: ❌ Not supported (dividers are not rendered) * **Inbox**: ✅ Full support with styling
