Extraction guide
BigCommerce and competitor data
Separate your store catalog from external observations.
01 / INPUTAuthorized catalog + competitor URLs
02 / YOUR WORKFLOWPreserve namespaces → compare fields
03 / OUTPUTA source-aware comparison plan
Keep the right fields.
Manual data handoff| Field / step | Input | Rule |
|---|---|---|
| Own catalog | Authorized merchant export | Keep its identifiers authoritative. |
| Competitor | Exact public source and variant | Request access review for that source. |
| Match | Verified cross-source mapping | An internal catalog API does not establish a competitor match. |
Before you use the output
Treat merchant access and external product collection as different steps. No native BigCommerce connector or access to another merchant's private catalog is implied.
Check one record first.
Start with the smallest useful scope. Compare the returned record with its source, confirm variant identity and inspect missing fields before applying the mapping to a larger dataset.
Keep extraction warnings and the retrieval timestamp with downstream output. When a required field is missing, leave it unresolved or return to the source; do not fill it from an assumption.
