🐇 I nibble at samples, add a friendly log,
Whispering responses through each tiny fog.
Templates and batches now show what they do,
A hop, a debug, a carrot-colored view. 🥕

117-134: Optional: Consider addressing pre-existing credential handling inconsistencies

While reviewing the changes, I noticed that several Node.js samples have inconsistent credential handling patterns:

  • Some use process.env.MAILTRAP_API_KEY (lines 370, 479, 635)
  • Some use hardcoded placeholders like "YOUR_API_KEY" (lines 123, 249)
  • Some have undefined ACCOUNT_ID references (lines 124, 250)

The PR improves some samples (e.g., createInbox now defines ACCOUNT_ID), but a broader cleanup could standardize the approach across all samples for better documentation quality. Based on learnings, placeholder strings are preferred for documentation clarity.

4110-4115: Fix applied: getHtmlMessage() now includes the required accountId parameter

The previous review correctly identified that the method signature requires three parameters: (accountId, inboxId, messageId). This change properly adds the ACCOUNT_ID constant and passes it as the first argument, fixing the API call.


377-378: LGTM - console.log additions improve sample clarity

Adding output logging to demonstrate API response data helps developers understand what to expect from each method. The pattern is applied consistently across the changed samples.


3041-3044: LGTM!

Extracting inboxId to a named constant improves readability and consistency with other samples.

62-91: Fix Node.js code sample syntax (missing comma in MailtrapClient config).

The sample currently has token: process.env.MAILTRAP_API_KEY without a trailing comma, which makes the snippet invalid JS—especially now that we’re adding more lines after it.

Proposed fix
             const client = new MailtrapClient({
-              token: process.env.MAILTRAP_API_KEY
-              // Add bulk: true for Bulk Stream
+              token: process.env.MAILTRAP_API_KEY,
+              // bulk: true, // Bulk Stream
             });
specs/sandbox.openapi.yml (1)

794-801: Node.js createInbox() sample uses projectId without defining it.

The snippet calls client.testing.inboxes.create(projectId, ...) but doesn’t define projectId, making the sample copy/paste-broken.

Proposed fix
             async function createInbox() {
+              const projectId = 12345;
               const inbox = await client.testing.inboxes.create(
                 projectId,
                 'My Test Inbox'
               );
               console.log(`Inbox created: ${inbox.name}`);
               console.log(`SMTP credentials - User: ${inbox.username}`);
             }
🧹 Nitpick comments (4)
specs/email-api.openapi.yml (3)

967-975: Keep Node.js samples consistent on token sourcing.

This block uses token: "YOUR_API_KEY"; other Node.js samples use process.env.MAILTRAP_API_KEY. Consider aligning to env-var usage for Node.js throughout (per repo guidelines).


1208-1213: Use a consistent ID placeholder type for templateId.

Adding templateId improves readability; consider making it obvious it’s an integer ID (as the path param is {email_template_id}), e.g. keep it numeric and name it templateId/emailTemplateId consistently across template examples.


1285-1290: Logging “template updated” is fine; ensure sample stays copy/paste friendly.

Looks good; same note as elsewhere: keep token setup consistent across Node.js examples.

specs/sandbox.openapi.yml (1)

2403-2409: Logging message is fine; consider removing duplicate consts inside showMessage().

You declare inboxId/messageId both outside and again inside the function; not a blocker, but it’s noisy in docs samples.

369-381: Fix Node.js sample placeholders: YOUR_ACCOUNT_ID is an undefined identifier (copy/paste breaks)

accountId: YOUR_ACCOUNT_ID will throw at runtime unless it’s defined; use a quoted placeholder or define a constant. Based on coding guidelines (code samples should be valid).

Proposed fix
             const client = new MailtrapClient({
               token: process.env.MAILTRAP_API_KEY,
-              accountId: YOUR_ACCOUNT_ID
+              accountId: "YOUR_ACCOUNT_ID"
             });

4533-4540: Fix argument order in Node.js code sample: getList() expects (inboxId, messageId) but sample has them reversed

The method signature is getList(inboxId: number, messageId: number), but the sample passes getList(67890, 12345) with arguments swapped. Should be getList(12345, 67890) to match the pattern used in other language samples (PHP, .NET, Java all show inboxId first, then messageId).


3971-3978: Fix incorrect client path for Node.js code sample

The method name and signature are correct, but the client path is wrong. Change client.testing.messages.getMessageHtmlSource(...) to client.messages.getMessageHtmlSource(...) per the official mailtrap-nodejs SDK documentation.


3206-3219: Fix forward() method signature: missing accountId parameter and incorrect body format

The forward() method signature in the mailtrap-nodejs SDK requires accountId as the first parameter and accepts an optional body object with the email property, not a string argument. The correct call is: client.testing.messages.forward(accountId, inboxId, messageId, { email: 'recipient@example.com' }). Also avoid logging the full result; instead show the relevant structure for documentation clarity.


3551-3558: Remove or correct the getHtmlAnalysis(...) code sample — method does not exist in mailtrap-nodejs SDK.

The client.testing.messages.getHtmlAnalysis() method does not exist in the mailtrap/mailtrap-nodejs SDK. The available testing.messages methods are: list, get/getById, delete, getHeaders, and getSpamReport/deliverability.

For HTML analysis, use the REST API endpoint directly: GET /api/accounts/{account_id}/inboxes/{inbox_id}/messages/{message_id}/analyze (requires account_id, inbox_id, and message_id), or replace this code sample with a method that exists in the SDK.

In `@specs/sandbox.openapi.yml`:
- Around line 794-803: The sample createInbox function passes an undefined
ACCOUNT_ID and logs sensitive data; update the client.testing.inboxes.create
call to either remove the undefined accountId parameter or replace ACCOUNT_ID
with a defined variable (e.g., const accountId = process.env.ACCOUNT_ID) and
ensure you never log inbox.password (remove any console.log printing
inbox.password and only log non-sensitive fields like inbox.username or
inbox.name). Ensure the change is applied in the createInbox function and the
arguments to client.testing.inboxes.create so the call uses a valid accountId or
omits it, and that only safe properties are printed.
- Around line 4106-4113: The sample calls client.testing.messages.getHtmlMessage
with only inboxId and messageId but the method signature expects (accountId,
inboxId, messageId); update the async function getHtmlMessage to pass the
missing accountId as the first argument (e.g., ACCOUNT_ID or a variable) when
invoking client.testing.messages.getHtmlMessage so all three parameters are
provided.

639-647: Same placeholder issue likely applies here (YOUR_ACCOUNT_ID bare identifier) + logging full delete result

If this snippet also uses bare identifiers for IDs, make them defined/quoted so it’s runnable. (Same issue as earlier comment.)

🧹 Nitpick comments (13)
specs/email-batch.openapi.yml (1)

69-91: Avoid logging entire batch response in docs samples (potentially huge / may include sensitive fields)

Prefer logging a small, stable subset (e.g., counts / IDs) to keep docs concise and avoid normalizing “dump everything” patterns. Based on coding guidelines (concise, developer-focused).

Proposed tweak
-              console.log("Batch sent:", response);
+              console.log("Batch sent. Responses:", response?.responses?.length);
specs/sandbox.openapi.yml (12)

483-490: Prefer not to log full project objects by default (may include share links / noisy output)

Consider logging a small subset (e.g., id, name) instead of the full object. Based on coding guidelines (concise docs).


920-928: Logging full inbox attributes may print password for admin tokens

Given TestingInbox.password can be present, prefer logging a safe subset (id/name/username) in docs samples. Based on coding guidelines.


1023-1031: Same concern: avoid dumping full delete results + keep sample variables defined


1142-1152: Same concern: avoid dumping full updated inbox object (may include sensitive fields)


1278-1286: Same concern: avoid dumping full clean result; consider a minimal log


1386-1394: Same concern: avoid dumping full mark-as-read result; consider a minimal log


1494-1502: Same concern: avoid dumping full reset-credentials result; consider a minimal log


1602-1610: Same concern: avoid dumping full enable-email-address result; consider a minimal log


1710-1718: Same concern: avoid dumping full reset-email-address result; consider a minimal log


2401-2410: Consider adding basic error handling in async samples to avoid unhandled rejections in Node.js

Even a minimal try/catch improves copy/paste experience.


2619-2632: Avoid redeclaring inboxId/messageId inside the function when already defined above

This is minor, but reduces confusion in docs and prevents accidental divergence of IDs.


2830-2839: Same: avoid dumping full delete result; consider logging result.id / status

Learning: In OpenAPI spec files under specs, particularly within x-codeSamples code examples, replace actual environment variable references with clear placeholders (e.g., YOUR_API_KEY, YOUR_ACCOUNT_ID) to avoid leaking secrets in documentation. Ensure code samples show substitute values and note how users should provide real values in their environment.

specs/email-sending-transactional.openapi.yml (1)

59-62: LGTM: harmless JS formatting change

specs/sandbox.openapi.yml (6)

3668-3675: No changes needed. The getTextMessage(inboxId, messageId) method signature in the code sample is correct and matches the mailtrap-nodejs SDK.


3036-3044: Method signature is correct; no changes needed

The SDK method client.testing.messages.get(inboxId) is accurate and matches the official mailtrap-nodejs implementation exactly.


4673-4680: Method signature is correct — verification confirms client.testing.attachments.get(inboxId, messageId, attachmentId) is the correct signature, and the code sample arguments are in the proper order.


3830-3837: Method signature is correct. The getRawMessage(inboxId, messageId) call matches the mailtrap-nodejs SDK implementation, which returns a Promise<string> containing the raw RFC-822 message body.


4268-4275: Method signature confirmed correct

The getMessageAsEml(inboxId, messageId) call matches the mailtrap-nodejs SDK implementation in MessagesApi.


4383-4390: No changes needed: getMailHeaders(inboxId, messageId) signature is correct

The code sample correctly uses the official mailtrap-nodejs SDK method signature. No refactor required.

specs/email-batch.openapi.yml (1)

64-67: Node.js sample configuration is correct per official SDK documentation

The code at lines 64-67 is properly configured. The MailtrapClient({ token: process.env.MAILTRAP_API_KEY, bulk: true }) pattern is confirmed correct by the official mailtrap-nodejs SDK docs, and the environment variable usage aligns with coding guidelines. No changes needed for this sample.
