Test mode

Use test mode when wiring a storefront before sending live customer work through StackFill.

Keys and sessions

API keys can be created in live or test mode. Embed applications and sessions also carry a mode. Use test keys for development and live keys for production storefronts.

curl https://api.stackfill.com/v1/embed/sessions \
  -H "Authorization: Bearer stackfill_test_sk_REPLACE_ME" \
  -H "Content-Type: application/json" \
  -d '{"external_product_id":"business-card","mode":"test"}'

Common handling

Keep test and live product mappings separate when possible. Do not store test fill IDs on production orders.
