I Will build an API or webhook sync with retries and a simple audit trail

What you get

A fixed integration pack for one named sync between your tools: an API path or webhook, with retries and a simple audit trail. Scope is locked before work starts. You keep your keys and hosting. We ship the slice or report what’s blocking — not an open-ended retainer.

How we work

1. You name the sync (source → destination) and share access, sandbox credentials, or sample payloads.
2. We lock scope on the private job-status page created for this order only (secret URL — not a shared portal). That page is where you ask questions, see updates, and hand off.
3. We implement the agreed slice: auth and payload contract on your stack, retry / failure handling, and a simple audit trail.
4. You get a working first slice (or a clear ship-or-report note) plus short handoff notes on that same page.

Deliverables

• Scope lock on one named source → destination sync
• Auth + payload contract on your tools
• Retry / failure handling and a simple audit trail
• Short run notes on the private job-status page
• Private job-status page for questions, updates, and handoff during the engagement
• Fast responses on that page while the slice is active

Turnaround

Typically 5–7 business days after we have credentials or a usable sandbox and the scope lock is confirmed. If access is delayed, the clock starts when access lands.

Packages

Use the package tier that matches how deep you need the first slice. The core outcome is the same: one named sync with retries and an audit trail inside a locked scope. Higher tiers add fuller failure handling, a second pass on your edge-case list, or a tighter handoff checklist — still fixed scope.

Experience and fit

We ship API and webhook glue for product teams who want a crisp first slice, not a vague hire. Samples: job-status page pattern and pack framing at https://cromservices.github.io/job-page-sample/ and https://cromservices.github.io/job-page-sample/packs/

Why this Zinn

Buyers often need one reliable sync between two systems before they invest in a bigger platform rebuild. This pack is built for that: named path, locked scope, retries, audit trail, private status page. You keep your keys. We do not host forever on our keys inside this fee.

Out of scope

Multi-system platform rebuilds, unbounded change requests inside the fixed fee, production on-call retainers, and forever hosting on Crom keys. Those are separate engagements if you need them after the first slice.

Client keys and privacy

Your credentials stay yours. The job-status page is private to this order. We do not invent live job tokens or ask you to email secrets — use the page for access notes when you are ready.

Give this pack a shot when you have a named sync ready. If you are unsure whether the path fits, ask on the private page after order and we will confirm scope before the clock starts.
