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 deliver the slice, or tell you plainly what's blocking it. 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 plain note on what's blocking it) 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
• Free fixes for 7 days after handover.

Want it watched after handover? The monthly care plan (from US$49) runs a test each month and fixes anything that broke.

Turnaround

2 to 4 business days, counted from access (credentials or a usable sandbox) once the scope lock is confirmed.

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.
