Marketplace operations
Marketplaces have APIs. They just don’t give you the numbers you need.
Amazon and the large marketplaces do have APIs, and they withhold the reports operators actually want, rate-limit the rest, and charge for the premium tier. Then there are the regional and niche marketplaces that have no API at all.
Eight marketplaces, three regions, one very dull morning
-
Sign in to each seller dashboard
Seller Central, then the regional variants, then the niche marketplaces. Each with its own MFA. Selling in three countries means three separate logins per marketplace.
-
Download settlement reports
The settlement report shows what you were actually paid after fees, which is not the same as what the orders report shows. Reconciling the two is the job.
-
Pull inventory and returns
Stock levels per warehouse, returns initiated, returns in transit, reimbursement status for the ones lost in a fulfilment centre.
-
Stitch it together
Into a sheet that tells you, finally, whether last week was actually profitable per channel.
Every dashboard, every region, in one scheduled pass
- Settlement report retrieval per marketplace and region, on the day it lands.
- Inventory snapshots across warehouses, so stock-outs surface before they cost a sale.
- Returns and reimbursement tracking, including the claims that need chasing.
- Regional logins handled separately: one session per region, isolated and independently revocable.
- Consolidated delivery by webhook into your warehouse or BI tool.
The combinatorics are the point: eight marketplaces times three regions is twenty-four logins a person does every morning.
Where this fits alongside the marketplace APIs
Use the API where it gives you what you need
If the official API returns the report you want at an acceptable rate limit, use it. Genuinely. PreLogin is for the reports the API withholds, the marketplaces without one, and the regional portals nobody integrated.
The regional variant problem
A marketplace that has an API in one country frequently does not offer the same endpoints, or the same data, in another. Sellers discover this when they expand. This is where a browser-based approach is often the only consistent option across regions.
Settlement reconciliation is the real job
The valuable output is not the download; it is the reconciliation between what orders say and what settlements say. Automating the retrieval is what makes that reconciliation possible to run daily instead of monthly.
The honest failure mode
Seller dashboards are among the most frequently redesigned surfaces we see, and layouts change without notice. Extractions will need occasional maintenance, usually a step edit, not a rebuild.
Start with your worst marketplace.
The one with no API, or the region nobody integrated.
