Workflow recipes

Step-by-step recipes connect multiple endpoints into a practical workflow and show how the API is used in production-style automation.

TLS automation with regfish certbro

Install regfish certbro, configure API access, issue a certificate with automated DNS DCV, and enable unattended renewals on Linux.

Safely update a DNS record with verification and rollback

Read a record by RRID, apply a targeted change, verify the result, and restore the previous state if necessary.

about 8 minutesDNSRollback

Maximize TLS lifetime with a re-issue cycle

Use a longer contract term efficiently by issuing certificates at the CA maximum validity, running follow-up issuances as re-issues, and starting the next contract period as an explicit renewal.

about 15 minutesTLSRe-Issue

Renew a TLS certificate explicitly

Create a new TLS order with `renewal_of_certificate_id` so the provider can explicitly treat it as a renewal of the existing certificate.
