Hire an Amazon SP-API Developer
I build production SP-API integrations for sellers, vendors, and SaaS teams — orders, inventory, financials, reports, and PII-safe workflows. Fixed quote up front, and you own every line of code.

"We were lacking functionality with third-party tools to apply our strategies. You really helped us implement our real strategies and improve the ROAS, ACoS, profitability and revenues."

Prices, up front
- API access, done with you $50
- Public app approval for SaaS $500
- SP-API deadline migration sprint $500
- Integrations and pipelines from $1,000
Sound familiar?
- Your SP-API application keeps getting rejected and you don't know why
- Reports randomly fail, throttle, or silently return partial data
- You need buyer names and addresses (PII) but the RDT flow is confusing
- Your data lives in Seller Central exports and someone pastes it into spreadsheets every morning
- Your dev team is busy and Amazon's docs are eating weeks of their time
If two or more of these hit home, tell me which. You'll get a plan and a fixed price within 12 hours, whether we work together or not.
What I build
Delivered as working software, not a slide deck.
Access & app setup, done right
Developer profile, roles, Solution Provider Portal, OAuth — approved the first time, with the compliance answers Amazon actually wants.
Order, inventory & financial sync
Reliable pipelines from SP-API into your warehouse (BigQuery, Postgres, Sheets) with retries, rate-limit handling, and alerting.
Buyer-PII workflows (RDT)
Restricted Data Token flows that legally pull buyer name and address for FBM shipping, invoicing, and customization — audit-safe.
Vendor Central reporting
RRA and retail analytics pipelines for 1P vendors, refreshed hourly, with reconciliation and backfills handled.
Proof
Recent builds in this exact area
Ops automation
PII access + Amazon Custom orders optimization (moomentsDE)
Enabled restricted/PII-safe order workflows and streamlined Amazon Custom order handling so the brand can process customizations faster, with fewer manual steps and fewer mistakes.
Custom orders processed faster with guardrails
Data pipelines
Vendor reporting: AMS + RRA pipelines (Alclear, Germany)
Delivered two production pipelines: Amazon Marketing Stream (AMS) in AWS for near real-time advertising signals, plus vendor retail reporting (RRA) pulls via SP-API to BigQuery — unified in Looker Studio for the PPC team.
One dashboard combining ads + retail signals
Integrations
Invoice generation automation (Mirakl + GreenInvoice)
Automated invoice creation and syncing by connecting Mirakl order events to GreenInvoice — with retries, validation, and clean status reporting for ops teams.
Invoices generated reliably, with fewer ops tickets

How to hire an Amazon SP-API developer
Whoever you hire, these five questions separate someone who has shipped SP-API work from someone who has read about it. Ask them of me too.
-
Can you show me a live SP-API call from an account you control?
Anyone can describe the APIs. A working call with real roles shows they have been through Amazon's developer registration and identity verification themselves.
-
Does my use case need the private (self-authorized) path or the public developer path?
Software for your own account and software other sellers authorize go through different Amazon reviews. Starting down the wrong one costs weeks.
-
How will you handle buyer PII and Amazon's Data Protection Policy?
Restricted roles bring an architecture review, encryption requirements and a limit of 30 days after delivery for keeping buyer PII. A vague answer here is how applications get rejected.
-
Who will own the code, the app registration and the refresh tokens?
They should live in your accounts. If your authorization sits on the developer's own app, you can't change developers without re-authorizing every seller account.
-
Which of Amazon's deadlines does this touch?
The old settlement reports go on 2026-11-11 and Orders API v0 on 2027-03-27. Code written today should already target the replacements.
Red flags: asking for your Seller Central password (OAuth exists so nobody needs it), promising guaranteed approval (Amazon decides), and a quote given before anyone has looked at which roles you need.
FAQ
Common questions
How much does an SP-API integration cost?
Simple single-endpoint automations start around $1,000, and getting API access approved on its own is a $50 working session. Full pipelines (orders + inventory + financials into a warehouse with dashboards) typically run $3,300–$9,900. You get a fixed quote before any work begins.
How long does it take?
Access + first working data pull is usually done inside a week once your developer profile is approved. Complete pipelines ship in 2–6 weeks depending on scope.
Do I need a Professional seller account?
Yes — SP-API access requires a Professional Seller Central account (or Vendor Central for 1P). If you're not sure your account qualifies, ask me before you spend time on the application.
Can you work with my existing developers?
Yes. I can deliver a working integration your team maintains, pair with them on the tricky parts (auth, RDT, throttling), or just unblock a stalled application.
Who owns the code?
You do. Everything is delivered into your repo and your cloud accounts. No ongoing software fees — the only recurring costs are your own infrastructure.
Where can I hire an Amazon SP-API developer?
Freelance marketplaces such as Upwork list plenty of Amazon API developers, agencies offer teams, and specialists like me do only Amazon's APIs. Whichever route you take, ask the five questions above: the answers separate shipped experience from familiarity within one call.
How do I check an SP-API developer actually knows the API?
Ask for a live call from an account they control, ask which approval path your use case needs, and ask how they would handle buyer PII under Amazon's Data Protection Policy. Someone who has shipped SP-API work answers all three specifically, with Amazon's own terms.
