A WP_Error points to a failure making the request; an HTTP response means a server replied, and its status, error body, and Anthropic request ID help identify what to fix. Those are different failure paths, so inspect them separately.
1. Separate transport failures from Claude API errors
WordPress’s wp_remote_post() returns either a response array or a WP_Error. Check for the error before trying to read a status or response body. The WordPress HTTP API provides helpers for inspecting a valid response; a response can still contain an error status rather than success.
If WordPress returns WP_Error
There is no Claude HTTP status to diagnose in this branch. Record the WordPress error code and message, with secrets and private prompt content removed. Then investigate the server-side request path: DNS resolution, outbound connectivity, TLS certificates, proxy or firewall behavior, and PHP or hosting configuration. The exact cause depends on the deployment; a WP_Error alone does not identify which part failed.
If WordPress returns an HTTP response
Capture the status and body with wp_remote_retrieve_response_code() and wp_remote_retrieve_body(), then parse the body as JSON. A returned response is not proof the Claude request succeeded: WordPress notes that response codes can include 3xx and 4xx statuses as well as 200. A malformed value passed to the status helper can result in an empty string, so make sure you are inspecting the response array rather than an error or unrelated value.

$response = wp_remote_post( $endpoint, $args );
if ( is_wp_error( $response ) ) {
// Record the WordPress transport error safely, with secrets redacted.
return;
}
$status = wp_remote_retrieve_response_code( $response );
$body = wp_remote_retrieve_body( $response );
$data = json_decode( $body, true );
if ( $status < 200 || $status >= 300 ) {
// Inspect the Anthropic error type/message and retain the request ID.
}This is an illustrative handling pattern, not a tested plugin implementation. WordPress also documents JSON request and response conventions for its own REST API; for a custom plugin’s upstream call, inspect the actual response from Anthropic rather than assuming every layer uses the same format.
2. Preserve the details that identify the failure
Anthropic’s error response includes an error type and message. Retain the request ID from the error JSON, commonly represented as request_id, or from the request-id response header. Anthropic says, “When contacting support about a specific request, include this ID to help us investigate the issue.” See Claude API Errors.

For each failed call, keep a concise, sanitized record of:
- Timestamp and endpoint path.
- WordPress
WP_Errorcode and message if no HTTP response exists, or the HTTP status if one does. - Anthropic error type and message, plus the request ID when present.
- Configured model identifier and a redacted indication of request size.
Do not log the Anthropic API key, full authorization headers, or private prompt content. These records help distinguish a transport problem from a rejected request or a service-side failure without creating a second security problem.

3. Route HTTP errors by status
Use the status to narrow the first check, then read the error type and message for the specific reason. The meanings below are those Anthropic documents in its API error guidance; a status is a starting point, not a complete diagnosis.
| Status | Documented meaning | First checks |
|---|---|---|
| 400 | Invalid request; Anthropic also documents some organization or workspace spending limits as 400 errors. | Inspect validation details, fields, and model-specific parameters. Check whether an account spend limit is involved. |
| 401 | Authentication error. | Check that the server sends the correct active Anthropic key. It may be malformed, revoked, expired, truncated, or replaced along a proxy or code path. |
| 402 | Billing error. | Check billing and payment status for the applicable Anthropic account. |
| 403 | Permission error. | Check organization or workspace access and permission to use the requested resource. |
| 404 | Requested resource not found. | Check the endpoint path and resource or model identifier. |
| 409 | Conflict with the current resource state. | Inspect the operation and whether concurrent changes or a uniqueness conflict occurred. |
| 413 | Request too large. | Reduce the payload or use a supported workflow; compare its size with the applicable Anthropic endpoint ceiling and your own host limits. |
| 429 | Rate limit, monthly spending cap, or certain workspace spending limits. | Inspect account usage and limits. Determine whether this is a transient rate limit or a spending restriction before retrying. |
| 500 | Unexpected internal API error. | Retry with exponential backoff. If it persists, contact support with the request ID. |
| 504 | Request timed out during processing. | Review request duration and consider streaming for long work. |
| 529 | API temporarily overloaded. | Treat it as temporary service overload and retry resiliently rather than flooding the endpoint. |
For request construction, verify the current endpoint path, authentication header, JSON encoding and content type, required fields, model identifier, and payload size. Model availability can change; consult Anthropic’s current model IDs and deprecation guidance rather than assuming an identifier in older integration code remains appropriate.

4. Retry only when the cause can clear
Transient rate limits and service errors
For a temporary rate limit or server-side error, use a bounded retry strategy with exponential backoff instead of sending repeated immediate requests. Anthropic specifically recommends exponential backoff for 500 errors and identifies 529 as temporary overload. Respect any retry guidance returned with the response, and avoid retrying so aggressively that the integration adds load during an outage.
Spending limits
A 429 can represent a spending cap rather than a short-lived rate limit. Anthropic notes that a spending-cap 429 may have no retry-after header and can persist until access resumes. Repeated retries will not resolve an account or workspace limit; check usage and spending settings instead. Some organization or workspace spend limits may also be reported as 400, so read the error body rather than relying on the status alone.

Long-running requests
A 504 indicates a timeout during processing. For lengthy operations, Anthropic suggests Messages streaming or Message Batches; it particularly calls out requests taking over 10 minutes when discussing those options. Choose a workflow that fits the task rather than assuming a synchronous WordPress request is suitable for every long-running call.
5. Distinguish Anthropic limits from WordPress host limits
Anthropic’s current Claude API error documentation lists these maximum request sizes by endpoint and says an over-limit request returns 413:
| Anthropic endpoint | Documented maximum |
|---|---|
| Messages and Token Counting | 32 MB |
| Batch | 256 MB |
| Files | 500 MB |
These are Anthropic endpoint ceilings, not guaranteed upload or request allowances for your WordPress installation. PHP, the web server, a proxy, or a firewall can impose separate deployment-specific limits before the request reaches Anthropic. If you see a transport failure or a size-related error, check both sides of the connection.
6. Keep the two authentication paths separate
A server-side WordPress integration authenticates its Claude API request to Anthropic with an Anthropic API credential. Keep that key on the server; never expose it in browser JavaScript.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsA WordPress Application Password instead authenticates a client to the WordPress REST API as a WordPress user. It is a revocable, per-application credential normally used with HTTP Basic Authentication over HTTPS. If the error is a WordPress REST 401 or 403, check that HTTPS is correctly detected, an Application Password—not the account’s ordinary password—is being used, the feature is enabled, and no proxy or client is stripping the Authorization header. Changing a WordPress Application Password does not fix a rejected Anthropic API key, and vice versa.
Quick Recap
7. A practical order for the next failed call
- Check whether
wp_remote_post()returnedWP_Erroror a response array. - If it returned
WP_Error, capture its code and message safely and investigate outbound networking, TLS, proxy, firewall, and hosting conditions. - If it returned a response, record the status, parse the JSON error, and retain Anthropic’s request ID from the body or header.
- Use the error type and status to check credentials, billing, permissions, endpoint, model, payload, request duration, or account limits as applicable.
- Retry only transient failures with backoff; resolve persistent spending restrictions or request-construction problems before sending the call again.
