What it does
Appfolio Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Diagnose and fix common AppFolio API integration errors. Trigger: "appfolio error".
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code
It sits in Backend & APIs, covering Third-party API integration. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBash(npm:*)Bash(curl:*)Grep
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
appfolio.comstatus.appfolio.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
APPFOLIO_CLIENT_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Context cost
Appfolio Common Errors loads about 1.8k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 744 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

AppFolio Common Errors
Overview
AppFolio's Stack API powers property management integrations for tenant screening, work orders, lease management, and accounting. Each portfolio operates under its own subdomain ({company}.appfolio.com), meaning a single integration may need to handle multiple base URLs. Errors commonly stem from authentication misconfiguration, incorrect base URLs per portfolio, and business logic violations like duplicate tenant records or conflicting lease dates. Tenant lookup failures (404) are the most frequent issue, typically caused by targeting the wrong portfolio subdomain. This reference covers HTTP-level failures, property-management-specific validation errors, and recovery patterns for the most frequently encountered issues.
Prerequisites
- A redacted incident record containing the portfolio identifier, endpoint, status code, request correlation ID, and time window; never copy tenant or lease payloads into a shared ticket.
- Access to the correct sandbox or production portfolio endpoint and a credential owner who can rotate or validate credentials without exposing them in logs or command arguments.
- A bounded retry policy, an idempotency mechanism for writes, and a known operator escalation path for uncertain tenant, lease, or work-order state.
Instructions
- Classify the response by authentication, rate-limit, validation, or server failure and preserve only the redacted diagnostic fields.
- Verify the portfolio base URL before changing credentials or retrying a
404; a valid tenant ID in another portfolio is not evidence of absence. - For
409or partial write failures, query the canonical record and use the operation’s idempotency key or operator review before issuing another write. - Honor
Retry-Afterfor429and stop after the configured retry budget; pause the batch on5xxor unknown write outcomes.
Error Reference
| Code | Message | Cause | Fix |
|---|---|---|---|
401 | Unauthorized | Invalid or rotated client_id/secret pair | Regenerate credentials in AppFolio Stack partner portal |
403 | Forbidden | Account not approved as Stack partner | Complete partner application at appfolio.com/stack |
404 | Tenant not found | Wrong portfolio base URL or deleted tenant | Verify base URL is {company}.appfolio.com/api/v1 |
409 | Lease conflict | Overlapping lease dates for same unit | Check existing leases on unit before creating new one |
422 | Validation failed | Missing required fields on work order or tenant | Include all required fields: unit_id, description, priority |
429 | Too Many Requests | Exceeded 120 requests/minute limit | Implement exponential backoff starting at 1s delay |
500 | Internal Server Error | AppFolio platform issue | Retry after 30s; check status.appfolio.com |
503 | Service Unavailable | Maintenance window (typically weekends) | Retry with backoff; subscribe to maintenance calendar |
Error Handler
interface AppFolioError {
code: number;
message: string;
category: "auth" | "rate_limit" | "validation" | "server";
}
function classifyAppFolioError(status: number, body: string): AppFolioError {
if (status === 401 || status === 403) {
return { code: status, message: body, category: "auth" };
}
if (status === 429) {
return { code: 429, message: "Rate limit exceeded", category: "rate_limit" };

}Debugging Guide
Authentication Errors
AppFolio uses HTTP Basic Auth with client_id:client_secret. Verify credentials are not URL-encoded. Each portfolio has its own base URL -- confirm you are targeting the correct {company}.appfolio.com subdomain. Credentials rotate on partner approval changes.

Rate Limit Errors
The Stack API enforces 120 requests/minute per API key. Batch tenant lookups instead of individual calls. Use Retry-After header value when present. Bulk endpoints (e.g., /properties?page=1&per_page=100) reduce call count significantly. Rate limits are per-key, not per-portfolio, so multi-portfolio integrations share the same budget.
Validation Errors
Work order creation requires unit_id, description, and priority. Tenant creation requires first_name, last_name, and email. Lease creation fails with 409 if dates overlap an existing active lease on the same unit -- query current leases first. Move-in and move-out dates must be valid ISO 8601 format. Unit IDs are portfolio-specific and cannot be reused across subdomains.
Error Handling
| Scenario | Pattern | Recovery |
|---|---|---|
| Tenant lookup returns 404 | Search by email before creating | Use /tenants?email= endpoint |
| Work order 422 | Missing priority field | Default to normal if unspecified |
| Lease date conflict | Overlapping active lease | End existing lease before creating new |
| Bulk import partial failure | Some records rejected | Parse error array, retry failed records only |
| Auth token expired mid-batch | 401 on subsequent calls | Re-authenticate and resume from last offset |
Quick Diagnostic
# Verify API connectivity without placing Basic Auth credentials in argv.
NETRC_FILE="$(mktemp)"
trap 'rm -f "$NETRC_FILE"' EXIT
chmod 600 "$NETRC_FILE"
APPFOLIO_HOST="${APPFOLIO_BASE_URL#https://}"
printf 'machine %s login %s password %s\n' "$APPFOLIO_HOST" \
"$APPFOLIO_CLIENT_ID" "$APPFOLIO_CLIENT_SECRET" > "$NETRC_FILE"
curl -s -o /dev/null -w "%{http_code}" --netrc-file "$NETRC_FILE" \
"${APPFOLIO_BASE_URL}/api/v1/properties"Output
- A redacted classification of the failure and the verified portfolio context
- A bounded recovery decision: correct configuration, delay/retry, reconcile, rotate through the credential owner, or escalate an unknown write result
- An incident receipt that identifies the affected batch without retaining tenant, lease, or credential data
Examples
When a work-order import receives 429, stop dispatching new records, retain
the batch cursor and idempotency keys, and wait for the server-provided retry
window before resuming at the same record. For a 409 lease conflict, query
the unit’s current lease through the correct portfolio and route the result to
an authorized operator rather than ending or replacing a lease automatically.
If the follow-up read is unavailable or the outcome of a prior write is
unknown, quarantine that record and continue only with unrelated safe work.
