Marketplace API migrations and upkeep

Marketplaces retire API versions every year. On Amazon that means Fulfillment Inbound v0, older Orders and Catalog versions, Ads API changes and Login with Amazon secret rotation; Walmart and the other channels move on their own schedules. We move your code to what is current and keep it there.

Why marketplace API migrations break things

  1. 1.

    A deprecation email arrives with a date and nobody owns it

  2. 2.

    New versions change fields, flows and limits, not just URLs

  3. 3.

    Business rules hide in code shaped around the old version

  4. 4.

    Credentials expire and the integration stops overnight

An integration that still calls a retiring API version is moved through a migration layer that keeps its logic, calls the current version, keeps marketplace credentials rotated and keeps operations running.deprecatedsame logicmapped callsrotateRETIRING VERSIONe.g. Inbound v0YOUR INTEGRATIONorders / shipmentsMIGRATIONmap / rewrite / verifyCURRENT VERSIONCurrent API versionsCREDENTIALSsecret rotationOPERATIONSkeep running

What the engagement covers.

  1. 01

    Deprecation tracking

    Each marketplace's retirement dates mapped to the code they affect.

  2. 02

    Version migration

    Calls, data models and flows moved to current versions: SP-API, Ads API, Walmart and the other channels you sell on.

  3. 03

    Logic preserved

    Business rules found in the old code and kept, verified against the old path.

  4. 04

    Credential upkeep

    Credential rotation and token handling kept current, Login with Amazon included.

  5. 05

    Ongoing upkeep

    A maintenance plan, so the next deprecation is a ticket, not an incident.

How it runs.

  1. P01

    Inventory

    Every call your code makes, matched to each marketplace's deprecation schedule.

  2. P02

    Plan

    Order of work set by deadline and risk.

  3. P03

    Migrate

    New calls and flows built alongside the old ones.

  4. P04

    Verify

    Both paths compared on real data before the switch.

  5. P05

    Maintain

    The next change handled as the marketplace announces it.

What you get.

Questions engineers ask us.

Q01Is this the MWS to SP-API migration?

That move is behind most sellers. This service covers what came after: version changes inside SP-API and the Ads API. MWS-era code is still welcome.

Q02How do we know which deprecations affect us?

We check your code and logs against each marketplace's published deprecation schedule and list every affected call with its date.

Q03Will the migration stop our operations?

No. New paths run alongside the old ones and are verified before the switch.

Q04Can you maintain it afterwards?

Yes, under a maintenance plan that covers marketplace API changes as they are announced.
