2025-10-05 21:09:33 +00:00 | 2 commits to main since this release1. Error Handling for Mullvad IP Fetch:
- Adds || { log "[!] Failed to fetch IP from Mullvad"; exit 1; } immediately after the curl command to catch curl failures explicitly.
2. Cloudflare Authentication Method:
- Switches to using Authorization: Bearer $CLOUDFLARE_API_KEY header for authentication, which is the preferred modern approach.
3. Required Environment Variables:
- Only requires ZONE_ID, DNS_NAME, and CLOUDFLARE_API_KEY. CLOUDFLARE_EMAIL is no longer mandatory for missing variable checks, but it's still used in some API calls.
4. Curl Exit Code Checks:
- Checks curl exit codes explicitly after each API call (GET, POST, and PATCH) and logs errors when curl fails.
5. Curl Headers Ordering and Content:
- The Authorization: Bearer header replaces X-Auth-Key in all API calls except the POST and PATCH, where both X-Auth-Email and Authorization coexist.
6. Curl Data Payload Ordering and Content:
- The order of fields in JSON payload has changed slightly (e.g., "name" before "ttl"), and the comment for creation and update changed from "Created via script"/"Updated via script" to "Domain verification record".
7. Additional Logging on Curl Failures:
- Adds detailed logging of curl failure responses and exit codes.
8. General Code Formatting and Minor Style Tweaks:
-
Minor changes in spacing and ordering of JSON fields.
-
Removal of some unnecessary blank lines.
-
Slight restructuring of error continuation logic.

Improvements:
Enhanced error handling and script robustness:
-
Added set -euo pipefail for stricter error handling and detection of undefined variables and pipeline failures.
-
Validates presence of required CLI tools (curl and jq) before execution.
-
Checks for the presence of .env files before processing to avoid errors if none are found.
-
Validates Mullvad API JSON response more robustly to detect missing or invalid IP information.
Improved environment variable management:
-
Switched from sourcing DNS_RECORD_ID to dynamically fetching the DNS record ID via Cloudflare API based on DNS_NAME.
-
Clearly logs missing required environment variables per .env file, specifying exactly which are missing.
Cloudflare API usage improvements:
-
Updated DNS record creation with POST request including correct headers (X-Auth-Email and X-Auth-Key).
-
Changed DNS record updates to use PATCH method instead of PUT, as per Cloudflare best practices.
-
Added support to create DNS records if they do not already exist, improving automation and flexibility.
-
Uses JSON data strings consistently and safely with proper quoting.
Logging enhancements:
-
Improved log messages for clarity on each step, including when no updates are needed.
-
Logs Cloudflare API responses on failure for easier debugging.
